4-channel Analogue Output Voltage / Current with CANopen - µ

The decentralized module µ features four analogue outputs which optionally provide a voltage signal (±10V) or a current signal (0-20mA). The digital process value is scaled to an analogue output signal in a rugged aluminium die cast casing. The CAN interface supports CANopen and J1939 protocols.


Due to its rugged casing in protection class IP66 the µ is ideally suited for field use. The analogue signals are transmitted a short distance to the sink, thus avoiding errors of the analogue signals. Via the CAN interface the module can completely be configured and the analogue variables are output.

  • 4 independent analogue outputs
  • Precise 16-bit D/A converter
  • Standard signals ±10V, 0-20mA and 4-20mA
  • Accuracy voltage output: 1mV
  • Accuracy current output: 1µA
  • Indication of device state via 2 LEDs
  • Extended ambient temperature range of -40°C...+85°C


Up to four analogue signals may be output, the signal type (voltage / current) is parameterized via CAN bus.

  • Voltage: - 10V .. +10V
  • Current: 0 .. 20 mA
  • Current: 4 .. 20 mA


The digital output values are transmitted to the µ via CAN bus. The bit rate of the CAN bus interface may be adjusted within a range of 50 kBit/s to 1 MBit/s. A terminating resistor may be activated via a switch in the device. The CANopen protocol of the module complies with the CANopen standards CiA 301, CiA 305 and CiA 404. Both 11 bit identifiers (CAN 2.0A) and 29 bit identifiers (CAN 2.0B) may be used on the process data.
