En CANopen distributed IO is an IO coupler integrated with a CANbus interface. It can be connected to a PLC that supports CANopen communication through the CANopen bus and act as a slave tool for the PLC.

We know that the realization of the functions of controllers such as PLC relies on a number of digital and analog IOs. However, the number of local IOs of PLC is limited after all. If we encounter projects with complex control content, it is necessary for us to increase the number of IOs. Since modern PLCs are all bus-type PLCs, we can completely expand IO by connecting IO couplers through the bus.

Taking the CANopen IO coupler mentioned in the title as an example, since the CANopen bus is born out of the CANBUS bus, its basic characteristics are the same as those of CANBUS. A CANBUS bus can theoretically support communication between hundreds of nodes at most. That is to say, a PLC that supports CANopen communication can connect hundreds of CANopen IO couplers. Due to the long communication distance of CANopen bus, the range of PLC control can be expanded, which is why CANopen distributed IO is also called CANopen remote IO device.

In order to meet your needs for CANopen IO couplers, we have developed a variety of related equipment, including digital input and output types, analog input types, current output types, and thermocouple input types. In addition, the expandable IO coupler has also been successfully developed. If you need equipment manual information, you can get it on the Support page of our official website.
