Application Notes
Applications
Relay Applications
Bosch relays were originally designed for use in automotive applications. The great range of different
versions are used in the most varied applications.
t Wiper motors
t Cooling fans
t Headlamps
t Electric window mirrors
t Central locking
t Fan motors
t Rear defrosters
t Electric seat adjustment
t Fuel pumps
t Security systems
t Starting motors
t Brake lamps
t Electric seat heating
t Horn
t Many other uses

In addition to these purely automotive applications, Bosch relays are ideal for switching 12V or 24V
components. This is true for both mobile and stationary applications, where for example, electric motors
are actuated. With these relays, a multiplicity of drive assignments can be implemented.
Bosch relays are employed in
t Automatic sliding doors
t Electric lawn mowers
t Control cabinets
t Emergency generators
t Cleaning devices
t Devices for the disabled
t Material handling technology
t Vending machines
t Agricultural equipment
t Robot controls
t Boat electric devices
t Garage door drives
t Battery chargers
t Furniture adjustments
t Toys

Applications
The Application Process
Consideration of the following
questions will aid in the selection
of the proper relay to suit your
application.
1. Type of load? (Resistive,
Motor, Lamp, Inductive)
2. Size of load? What is the
number of Amps being switched
ON, carried during steady state
performance, and being switched
OFF?
3. Time–Current curve? For a
motor or lamp load, what are the
magnitude and duration of the in
rush peak current during turn
ON?
4. Multi-tasking? Will one relay
part number “A” switch a lamp for
example in one circuit, and a
second relay part number “A”
switch a resistive load in another
circuit?
5. Duty cycle? What is the
expected ON (running) time for
your load, and the expected OFF
(resting) time?
6. Temperature conditions?
What are the minimum and
maximum storage and operating
temperatures the relay will
experience?
7. Relay life? How many
switching cycles are required?
8. Coil suppression? Will ahttp://www.DataSheet4U.net/
resistor or diode in parallel to the
coil be required to suppress a
negative drop out voltage spike
when the coil is de-energized?
(This protects other devices in
your circuit.)
9. Method of mounting? Will
the relay be plugged into a power
distribution center, or be
mounted via a bracket?
10. Are other devices required?
Will you require mounting
connector modules and their
related terminals?
