The Wheel sensor Signal Converter WSC processes the wheel sensor information of the wheel

sensor RSR110-001 and the wheel sensor RSR110-002.

The wheel sensor RSR110-001 is equipped with 2 sensor systems and can output information

regarding the status of the sensor systems (damped, not damped or faulty) and information regard-

ing the direction of a traversing.

The wheel sensor RSR110-002 is equipped with 1 sensor system and can output information

regarding the status of the sensor system (damped, not damped or faulty).

The WSC can be combined with:

•1 wheel sensor RSR110-001

•1 wheel sensor RSR110-002

•2 wheel sensors RSR110-002

The WSC supplies the wheel sensor(s) with voltage and converts the analogue signal of the wheel

sensor(s) into digital signals. The digital signals are transmitted as digital switching signals to a

higher-ranking system via optocoupler. At the outputs, a traversing and/or the direction of the

traversing is output.

The sensor current depending on the occupancy of the wheel sensor is evaluated level-related by

the WSC. Based on the normal operating sensor current of the sensor system, a current change

can be detected downwards or upwards and results in a respective switching operation at the

interface.

Errors are indicated via the LEDs “Sys1” and/or “Sys2” on the front panel of the WSC.

The WSC complies with the requirements of SIL 0.

The required information and prerequisites for the application of the wheel sensor RSR110-001 are

described in the documentation D4232 “Application guide wheel sensor RSR110”.
