3-CH analog output / CANopen module ZC-3AO

The ZC-3AO supplies 3 single-ended analog signals (voltage or current type), with two types of communication: CANopen protocol, ModBUS protocol (RS232 serial).


  • Analog outputs either in current 0–20 mA or in bidirectional voltage -10 – 10 V.
  • High accuracy and resolution.
  • Fast response time (typical <20ms).
  • 1500 VAC isolation amongst outputs, power supply and CAN interface.
  • CAN Interface with CANopen protocol: up to 1 Mbps speed.
  • CANopen Baud rate and Node ID configurability by DIP-switches or software.
  • Protection against ESD discharge up to 4 kV.
  • Adjustable rejection at 50 and 60Hz.
  • Simplified power supply and serial bus wiring by means of the bus housed in the DIN rail.
  • Output protection, both in voltage output (against short circuit or applied voltage) or in current output (against applied voltage).
  • Node guarding or heartbeat.
  • RS232 Serial Communication with MODBUS-RTU protocol.
