Introduction
Programmable Logic Controllers (PLCs) are widely used in industrial automation, controlling a variety of processes like assembly lines, machinery, and lighting systems. One of the key elements in a PLC system is the Control Relay, a logical tool used within the PLC to manage and simplify control operations. Unlike physical relays, which are mechanical devices, a PLC Control Relay exists entirely within the software of the PLC. This article will delve into the concept of PLC Control Relays, their functioning, uses, and their significance in automation systems. What is a PLC Control Relay?
