INTRODUCTION
A small component with a big history
From the telegraph to automotive engineering
The relay owes its name to former times when mail was still
carried by horse. At what were known as relay stations, post
riders could swap their horses for rested ones. Today, we call
an electromagnetic, remotely operated switch a relay.
The American physician Joseph Henry invented the electric
relay in 1835. The pioneer in communications engineering
used it to send messages from his laboratory to his home.
Relays were first used on a larger scale in 1837, as signal
amplifiers for Samuel Morse’s recording telegraphs. They
would later make possible the widespread use of telephones
and became a cornerstone of safety in railway engineering. In
1941, Konrad Zuse utilised 2,000 relays in his legendary Z3, the
first digital computer. HELLA produced its first automotive
relay in 1960.
As electronics matured in the 20th century, the age of the relay
was often seen as over; nevertheless, they retain a place in
specific applications. The automotive industry, for example,
needs relays, since relay functions cannot always be replaced
by control units. Only relays make galvanic isolation possible
between input and output. Semi-conductors cannot manage
this at the moment. The cost advantage relays have over
electronic solutions is also unbeatable.
Relays are used in automotive engineering to switch high
currents. The engine control unit, for example, is switched by a
relay. Because relays are robust and not particularly
susceptible to failure, they can be installed near electric
devices. They require only low control currents, making small
line cross-sections sufficient. The switching and amplifier
function of a relay could only be achieved with a lot more effort
and a lot less reliability using more “modern” electronics.
Another benefit of the relay is that it is quick and easy to
replace. These positive characteristics are the reason why
relays are still in use. And they ensure that, in the future, relays
will still be at home in many vehicles.
Relays have been used to remotely control circuits for over 180 years. The technology has proven its
reliability millions of times and is today still the first choice for many applications, such as in automotive
engineering.

■ Design life tests:
The relays are switched on/off in cycles on fully automated
test racks. Original loads or simulated resistive, inductive,
capacitive or combined loads whose current characteristics are
recorded as the original loads are connected. In addition, the
relays can be subjected to different ambient temperature
ranges or temperature profiles. The test is continuously
documented.
■ Electrical parameters:
Within the context of product release, starting voltage, dropout
voltage, contact voltage drop, coil resistance and insulation
resistance are tested, for example. Accompanying the
manufacturing process, the electrical parameters are recorded
at the end of the production process by end-of-line testers.
These can be evaluated statistically. One important factor for
guaranteeing the consistent high quality of the relays
produced.
■ Environmental and mechanical tests:
Every relay has to pass tests such as the alternating
temperature test, salt spray fog test, mechanical shock test or
drop test and the vibration test within the context of the
product release process. These tests are carried out using
HELLA equipment.
■ Analytical tests:
Here, the materials used and the different connecting
processes such as soldering and welding are tested. The tests
are carried out randomly during incoming goods testing and
following production.
■ Certificates:
HELLA has been certified in a range of relevant areas e.g. DIN
EN ISO 9001:2008, ISO / TS 16949:2009, ISO 14001. HELLA
relays also comply with the ROHS (2002/95/EC) and REACh
standards.

Functional principle
Relays are basically electrically operated switches which use an electromagnet to move a switching mechanism by
switching one or more contacts. They are used where one or more load circuits need to be switched on or off by
means of a control signal. Characteristic of the electromechanical relay is the complete (galvanic) isolation
between the control and controlled circuits.
Make relays
Make relays are used to close an electric circuit between a power source and one or more electrical loads, i.e. the
loads are switched on. Relays are operated by means of switches, pulse generators or control devices. Typical
vehicle applications are headlights, auxiliary lights and fog lights, horns, heaters, air conditioner systems, etc.
How make relays work
Fig.1) The control circuit (86/85) is inactive and the return spring keeps the armature open. The make contacts are
open and the load circuit (30/87) is interrupted.
Fig. 2) The control circuit (86/85) is active and the copper coil induces a magnetic field which pulls the armature
down onto the magnetic core. The make contacts are closed and the load circuit (30/87) is therefore also
closed.
Change-over relays
Change-over relays switch the load circuit over from one electrical load to another. These relays can be operated
by a dashboard switch, for example. Change-over relays are used for switch applications with two stages/speeds
such as heated rear windows or fan motors etc.
How change-over relays work
A change-over relay operates on the same principle as a make relay. The only difference is that the armature is
connected to a second (alternative) output (87a) when released. As soon as the control circuit is active, the
armature is pulled in, opens the break contact (87a) and switches over to the make contact (87). A change-over
relay can be used as either a make or a break relay. By design, the switching current of the make contact is always
higher than that of the break contact.
Rated voltage
12 V: for passenger cars, agricultural and construction machinery etc.
24 V: for commercial vehicles, buses, municipal vehicles etc.

Resistive load:
The current remains around the same
from switch-on to switch-off (e.g. rear
window heater).

ELECTROMECHANICAL RELAYS
Inductive load:
The inrush current increases to the
rated current with a specific delay time
due to the build-up of the inductor’s
magnetic field and then levels off (e.g.
switching on a solenoid switch). During
switch-off, a voltage of up to
several thousand volts is (theoretically)
induced, resulting in an electric arc
between the relay contacts just opened.
Capacitive/bulb load:
The inrush current of a capacitive load
or a lamp can rise to ten times the rated
current before leveling off to the rated
current.

In order to prevent voltage spikes caused by mutual inductance when switching off the coil current, our relays are
in part equipped with resistors or diodes parallel to the coil.

Summary of battery disconnect and solid state relays
Solid state relay
Semi-conductor relays, designed for resistive, lamp and
inductive loads
Pulse width modulation (PWM) makes controlled power
regulation of loads (up to 1 kHz) possible
Maximum switching safety, particularly suitable for all safety-
related switching functions
In terms of design size and plug matrix, compatible with
conventional ISO mini relays (standardised dimensions
according to ISO 7588-1)
Silent switching e.g. in the passenger compartment
Resistant to short-circuit and excess load
Resistant to reverse polarity
Impact and vibration-resistant
Sealed and waterproof
Overheating protection
Low quiescent current
The solid state relay is a modern semi-conductor switch and
makes switching possible without moving parts. It can be
connected via standardised pin bases.
With this development, HELLA is doing justice to the increasing
trend of controlling loads (e.g. fan motors, glow plugs, headlights
and heaters) using power regulation. The increased switching
frequency makes continual setting by means of pulse width
modulation (PWM) possible e.g. for daytime running lights.
The silent semi-conductor relay is particularly attractive for use
inside vehicles. In addition, the wear and bounce-free switching
means it can be used for applications with a high number of
switching processes e.g. ABS or air-conditioning compressor
clutch or vacuum pump for brake booster support in hybrid
vehicles made by leading OEMs.
Battery disconnect relay
Disconnects the vehicle electric system from the battery, as a
component of vehicle electric system control units and pre-
fuse devices
Battery charge is maintained by avoiding quiescent current:
large vehicle electric system parts are switched off during
longer periods of vehicle standstill
Voltage to the vehicle electric system or its parts is interrupted
for maintenance work
Safety switch-off in the event of an accident or cable damage
to avoid fire hazard
Advantages:
Mechanically bi-stable switching unit:
Impulse at the closing coil closes the contacts, these are
stopped mechanically, impulse at the opening coil opens the
contacts
Contact bridge double breaking
All load circuit components with large cross-section (>30 mm²)
for high continuous current carrying capacity
Coil terminal:
2-pole or 4-pole AMP connector

Functional principle
In terms of circuitry, every flasher unit is an “astable multivibrator”. Its role is to operate blinker lights at the
statutory frequency of 1.5 +/- 0.5 Hz or 90 +/- 30 rpm. This value applies to both directional and hazard
warning lights.
Each flasher unit is assigned a separate output load or a permissible number of flashing indicator lights. This
specific load case variant may not be exceeded or undercut, as otherwise the failure control will fail to work
correctly. Some typical load cases which are supported are shown below:
Scenario Direction flashing Hazard warning flashing Pictogram
Towcar only 2 x 21 W 4 x 21 W
2 x 21 W + 0 … 5 W 4 x 21 W + 2 x 5 W
Towcar + 1 trailer 2 + 1 x 21 W 6 x 21 W
2 + 1 x 21 W + 0 … 5 W 6 x 21 W + 2 x 5 W
3 + 1 x 21 W 8 x 21 W
3 + 1 x 27 W (32 CP) + 3 W (SAE) 8 x 27 W (32 CP) + 2 x 3 W (SAE) –
4 + 1 x 21 W 10 x 21 W
Towcar + 2 trailers 2 + 1 + 1 x 21 W 8 x 21 W
In addition to the load cases above, there are other use cases which do not feature failure control. These variants can be found in the tabular overview
from page 38 on.
The failure of an indicator light must be clearly displayed to the driver. The law permits failure control by
doubling the flashing frequency (E-control) or the indicator control lamp remaining off (P-control). The failure
control applies to motor vehicles and all trailers.
Segmentation into different current and control circuits is typical of flashing circuits. We distinguish between:
• Single-circuit flasher units
• Dual-circuit flasher units
• Three-circuit flasher units
• Pulse generators
In addition to the flasher circuits listed above, HELLA also supplies pulse generators. In principle, these are
flasher units without failure control. In contrast to the above types, pulse generators can be operated with
small loads (e.g. 10 W).

The single-circuit test circuit
Single-circuit units are used in load cases (per 21 W
bulb) 2x, 4x, 5x, 2+1, 3+1, 2+1+1 for passenger cars,
light commercial vehicles and tow vehicles. It is not
possible to distinguish between the failure of a lamp
on the towcar or on the trailer, as there is only one
measuring resistor for the load current.
The dual-circuit test circuit
Dual-circuit units (separate test circuits for trailer and
towcar) are typical in large commercial vehicles and
help to minimise power losses caused by long cables
and numerous connectors.

The three-circuit test circuit
Three-circuit units (separate test circuits for front and
rear indicators of the towcar and of the trailer) are
useful for commercial vehicles and buses and help
to minimise power losses caused by long cables and
numerous connectors.
Due to the complexity of wiring, they are less common.

As indicators must be checked by law, we recommend operating
the lights only in conjunction with a failure control according to ISO
13207-1.
For LED indicators with a control pulse, HELLA offers electronic
ballasts which make it possible to display indicator failure for
various vehicle assemblies and modifications. This is necessary if
the vehicle manufacturer does not guarantee indicator bulb failure
control via the vehicle electric system.
There are three different ballasts and several different LED
indicators available:
As a new solution, HELLA recommends detecting the electrical
pulse directly in the vehicle manufacturer’s vehicle electric system.
It is merely necessary to integrate the check according to ISO
13207-1. This obviates the need for interim solutions via the
indicator control units.
Legal requirement in all ECE states
In the case of vehicles approved for use on public roads, the
indicators must be monitored: the failure of an indicator must be
shown optically or acoustically in the vehicle. This applies to all
ECE states in which regulation ECE R 48 is in effect. This means
possible indicator failure must be monitored by the vehicle.
Manufacturers use different control procedures for this.
The failure controls currently in use cannot detect simple LED
lights and indicate a fault. Many HELLA LED indicators have
integrated failure control electronics. The indicators are self-
monitoring. When functioning correctly, they create a pulse
according to ISO 13207-1 which can be evaluated by the vehicle
electronics. If the available vehicle electronics cannot evaluate the
pulse themselves, HELLA provides various solutions for
evaluating this pulse, shown below.
As soon as one single LED fails, the light can be considered faulty,
the impulse is not generated. In this case, for instance, the ballast
switches off the bulb simulation and the flasher unit reports the
error to the driver.

LED indicators and failure control from HELLA
LED light failure control and correct electrical connection
Operation of the LED lamp with alternating voltage or clocked direct voltage is not
permitted. The individual light functions may only be operated with a vehicle fuse of max.
3A.
Due to the low watt output of LED lights, which are distinctly different from a bulb
version, problems can arise in bulb failure control when operating traction vehicles. As
checking of the indicators is required by law, we recommend operating the light only in
conjunction with the indicator control unit, HELLA part no. 5DS 009 552-xxx.
In addition, further lighting functions are detected by some towing vehicles. This is a
vehicle comfort function which is not required by legislation and does not release drivers
from their obligation to see for themselves that the lighting equipment is working. Here,
too, faulty diagnosis can occur on account of the low power levels involved (instrument
panel in the driver cab indicates light failure although the function is working).
Should misdiagnosis occur, as described above, while operating your traction vehicle,
please contact the traction vehicle manufacturer.

In future, vehicle manufacturers’ light control units will be able to check the failure
pulse in a standardised and unified manner according to ISO 13207-1.
Interim solutions 1 to 3 are therefore unnecessary, as communication takes place
directly with the indicators. HELLA recommends this solution.
Since not every vehicle currently has its own vehicle electric system, this solution
must be integrated.

Functional principle
The wash/wipe interval control unit essentially comprises a pulse generator with a fixed or variable pulse/pause
ratio. Every pulse with which the wipe/wash motor is controlled via a relay causes a one-off back-and-forth
movement of the windshield wipers. Depending on the design, the length of the wipe pause is 4 s to X s.
The WWI control unit comprises the following:
PCB with electronic components, blade terminals and a PCB relay
Synthetic material housing, sometimes with holder
Similarly to flasher units, the timer is designed as an astable multivibrator in the wipe/wash interval control unit. A
failure control stage as required by the flasher system is not needed for the WWI control unit.
HELLA also supplies headlight washer systems which clean the headlights using a spray of high-pressure water.
Depending on the variant, the length of the spray varies between 0.4 s and 0.8 s.

Functional principle
A time relay is a monostable flip-flop with connected relay.
The time relay is available in two variants:
Pick-up delay: the monostable flip-flop is activated by applying a voltage to the device input. Depending on the
set time, the relay is then switched on with a delay. After deactivating the input, the relay voltage drops
immediately.
Drop-off delay: the relay is switched on immediately by applying a voltage to the input of the monovibrator.
After deactivating the input, the relay voltage drops after a predetermined time.
HELLA also supplies time relays with neither pick-up nor drop-off delay. In this case, the output is activated or
switched on for a specific period of time.
The delay or turn-on time can be adjusted with a DIP switch and fine-tuned with a potentiometer.
If a more powerful relay is used, higher current strengths or different load types – e.g. inductive, capacitive/lamps
– can be easily activated.
