The electronic relay EXR10 (Electronic eXtra Relay) is a solid state

relay combining various extra functions in a single unit. These include:

l

Solid state relay with diagnostic functions such as low voltage

monitoring, wire break detection and current-proportional voltage

output

l

Electronic overcurrent protection

The relay fits into 4-pole or 7-pole standard automotive relay sockets

to ISO 7588 (ISO Mini). It is suitable for system voltages of DC 12 V

and DC 24 V (operating range DC 9...32 V) and can switch currents

between 1 and 30 A.

For remote switching and protection of loads, two separate

components had up to now often to be connected in the load circuit

as a functional unit:

l

An electro-mechanical relay or solid state relay which is powered

via the control cable and then closes the circuit by means of the

integral contact or power semi-conductor.

l

An additional protective element (circuit breaker or fuse) providing

line or equipment protection in the event of a failure.

The EXR10 combines diagnostic functions with overcurrent protection in

a single component, thus minimising the number of connections in the

circuit and reducing the failure risk. In addition the ETR10 is remotely

resettable after overload tripping if an overload in the load path has

caused the relay to switch off.

Applications

The EXR10 is suitable for all applications in DC 12 V and DC 24 V

on-board electrical systems where magnetic valves, motors or lamps

have to be switched and protected:

l

Road vehicles (passenger cars, bicycles, trucks, buses, working

vehicles and emergency cars, special vehicles)

l

Construction vehicles and agricultural vehicles

l

Rail vehicles

l

Watercraft (ships, sailing boats, motor yachts etc.)

l

Industrial process control and production technology

l

Diagnostic functions regarding current, voltage or wiring can

individually be adjusted to applications

l

Plus-switching (positive control) solid state relay with high side

switch (HSS) for load currents between 1 A and 30 A

l

Integral protection against short circuit and overload in the load

circuit

l

Remotely resettable upon detection and disconnection of

overcurrent by means of the protective function

l

Silent switching

l

Wear-free and robust design, insensitive to shock, vibration and

dust (no mechanical contacts)

l

Very low closed current and switching current consumption

l

Fits into standard ISO Mini automotive relay sockets
