8-channel Digital Input / Digital Output with CANopen - µCAN.8.dio-BOX

The 8 terminals of the µCAN.8.dio-BOX may individually used as digital inputs or digital outputs. The digital signals are preprocessed and filtered in a rugged die-cast casing. The CAN interface supports CANopen and SAE J1939 protocols.


The µCAN.8.dio-BOX is a freely configurable digital I/O module. Module address and bit rate may be adjusted either via dip switch or CAN bus (LSS, CiA305). Auto-bit-rate detection is supported as well. Wires for power supply, CAN bus and signals are connected via cable glands, customized connectors may be applied upon request.

  • CAN protocol: CANopen CiA 401
  • Aluminium die-cast casing, protection class IP66
  • 8 connectors, freely configurable as inputs or outputs
  • Digital inputs: 3-conductor connector for sensor supply
  • Digital outputs: short-circuit protected, max. load 1.4 A
  • Maximum total current 6 A
  • Output drivers may be supplied separately
  • Indication of device state and errors via LEDs


Up to 8 digital signals may be processed which are configured (digital input / digital output) via CAN bus.

Switching threshold, edge detection and filter of the digital inputs are freely configurable. The digital outputs are available as high-side drivers (plus switching, PNP).


The process values for digital inputs and digital outputs of the µCAN.8.dio-BOX are transmitted via CAN bus. The bit rate of the CAN bus interface is adjustable within a rnage of 50 kBit/s to 1 MBit/s. A terminating resistor may be activated vie a switch in the device if required. The CANopen protocol of the module complies with the CANopen standards CiA 301, CiA 305 and CiA 401. Both, 11 bit identifiers (CAN 2.0A) and 29 bit identifiers (CAN 2.0B) may be used on the process data.
