Overview
The FC2021C switch quantity module is an independent module based on the CANOpen communication protocol. It can output switch quantity data in the CAN network through relays, measure switch quantity signals through switch quantity input channels, and send the results to the CAN network. The switch quantity output can be directly associated with the switch quantity input, and it can also be controlled by a computer.
