PLC

Programmable Logic Controllers (PLCs)

Programmable logic controllers are the brains of automated machinery, running the control program that reads sensors and drives actuators. LED Controls Ltd supplies PLCs from Unitronics, ABB (AC500 and AC500-eCo), Wago, IMO and Lovato – from compact controllers with onboard I/O to modular CPUs with Ethernet, Modbus, PROFINET and EtherCAT.

Filter by brand, then compare CPU size, onboard I/O and communications. Pair your controller with expansion I/O, an HMI touch panel and the right cables and modules, or choose an all-in-one HMI & PLC for smaller machines.
