A programmable logic controller (PLC) is an industrial solid-state computer which has been adapted for the control of manufacturing processes. To put it briefly, the function of a PLC is to monitor ...

A Programmable Logic Controller is “a small industrial computer originally designed to perform the logic functions executed by electrical hardware (relays, switches, and mechanical timer/counters),” ...

Learn the purpose, features, and benefits of programmable logic controllers (PLCs) for automation and control systems in electrical design.

When talking about automation, we’d have to look back at the late 1960s and the importance programmable logic controller (PLC) has had on the industry, being an essential factor as far as ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1.

Programmable logic controllers (PLCs) are the workhorse computing systems that help to coordinate and harmonize functions performed by the multitude of sensors, actuators, conveyors and many other ...

INTERNAL AND SYSTEM CONTROL RELAYS. A very useful set of built-in control relays (again, not physical relays — memory registers) are available for you to use with the Click (and most other PLCs).
