CANopen Transmitters for Voltage and Current Measurement - µ

The cable transmitter in protection class IP67 is designed to acquire an analogue signal. The cable transmitter is directly integrated in the measuring wire. The analogue measurement signals are transmitted to the µ via short lines. They are then digitalized and transmitted by CAN interface to a processing unit.  


Due to its robust IP67 rated design the µ module may be installed directly in the field. The analogue signals are send over a short distance from the source minimizing interference effectively. Configuration of the device and scaling of analogue measurement values is set via the CAN interface.

  • measurement fo voltages (+/-10V)
  • measurement of currents (0-20 mA / 4-20 mA)
  • 16-bit resolution
  • plug-in connector M12
  • protocol: CANopen CiA 404
  • indication of deviation from measurement range
  • extended ambient temperature range of -40°C...+85°C


The module version µ / voltage is able to measure voltages within a range of +/- 10 V. If you want to measure currents within a range from 0 to 20 mA we recommend our µ / current module version. In both module versions the power supply voltage has been placed on two pins of the sensor input.


The digitized analogue values of the µ are send via the CAN bus. The bit rate of the CAN bus interface may be set within a range of 50 kBit/s to 1 MBit/s. The CANopen protocol of the module is in compliance with CANopen standards CiA 301, CiA 305 and CiA 404. Both 11-bit identifiers (CAN 2.0A) or 29-bit identifiers (CAN 2.0B) may be used on the process data.
