Systec CANopen IO-C12

The CANopen IO-C12 is a compact CANopen I/O extension module with outstanding performance.

The CANopen IO-C12 is a compact CANopen I/O extension module with outstanding performance. It makes accessible a well thought out compilation of industrial proven I/O via CANopen network variables and combines it with features of network management and node guarding in a compact DIN-rail mountable case. Clearly arranged LED indicate the status of every I/O at the first glance. Removable terminal blocks enable easy deployment and exchange of modules.

For use in decentralized applications, you can easily and quickly expand your automation system with the CANopen IO-C12 IO device.

The CANopen IO-C12 has a CPU core including the pre-programmed firmware for CANopen communication and the peripherals for the industrial inputs and outputs. Extensive diagnostic functions ensure reliable and safe operation.

All inputs and outputs of the CANopen IO device as well as configuration parameters are accessible via the CANopen protocol. The CANopen IO-C12 is a CANopen slave device according to the CANopen device profile CiA 401 and the CANopen communication profile CIA 301 V4.02. LEDs indicate the device status according to CiA 303-3 V1.0.
