I/O Systems

I/O Systems and Expansion Modules

I/O systems extend a controller with the digital and analogue inputs and outputs a machine actually needs – thermocouple and RTD inputs, relay and transistor outputs, high-speed counters and fieldbus-coupled remote I/O. We stock expansion modules and remote I/O for ABB AC500, Unitronics, Wago, IMO and Lovato platforms.

Match the module to your controller family using the brand filter, then check channel count and signal type. The controllers themselves are under PLC and HMI & PLC combinations; network couplers and gateways are under Remote & Network.
