Logic Relay

Programmable Logic Relays (Smart Relays)

A programmable logic relay – often called a smart relay – replaces a handful of timers, counters and control relays with one compact, DIN-rail unit programmed in ladder or function-block logic. Ideal for simple machines, pump control, lighting and building automation. We stock IMO iSmart, Finder OPTA and Lovato logic relays, many with built-in displays and Ethernet.

Compare I/O counts and supply voltages with the filters. When an application outgrows a logic relay, step up to a full PLC or an all-in-one HMI & PLC; for standalone timing functions see time relays.
