AC I/O & Relay Outputs

Need help selecting CLICK PLC components?
Use our configuration tool to configure and order.

PLC discrete AC I/O modules allow monitoring and control of ON/OFF signals and devices that operate with AC voltages up to 240 VAC, such as power relays, pumps and motor starters. Relay modules provide NO/NC contacts that switch user-supplied power on and off internally, allowing for higher current loads. Several CLICK AC I/O and relay modules are available.
