Systec CANopen IO-X3, 24DO

Compact & cost effective CANopen remote I/O module

Extensive diagnostic functions ensure reliable & safe operation

The CANopen IO-X3 is a very compact and cost effective CANopen IO module featuring a high-density of industrial proven IO's.

The module includes a CPU-core including the pre-programmed firmware for CANopen communication and peripherals for the industrial inputs and outputs. Extensive diagnostic routines are implemented to ensure a most reliable and safe operation.

All inputs and outputs as well as configuration parameters are accessible via the CANopen protocol.

The CANopen IO-X3 is a CANopen slave device according CANopen device profile CiA 401 V2.1 and CANopen communication profile CiA 301 V4.02.

Two LED indicate the device state according to CiA 303-3 V1.0.
