An Automation Relay is an electrical device used to control the switching of circuits in automation systems. It is essentially an electrically operated switch that opens or closes circuits based on a low-power input signal, typically coming from a control system like a Programmable Logic Controller (PLC). Relays enable the control of large electrical loads (such as motors, lights, or heating elements) with minimal power from the control system.

    Functions and Importance

    The primary function of an Automation Relay is to act as an intermediary between a control circuit and a load circuit, ensuring the proper operation of various devices without overloading the control system. These relays receive control signals (either from a PLC or other controllers) and respond by opening or closing a set of contacts that control high-power equipment. This process allows automation systems to operate seamlessly, with the ability to manage large-scale equipment while minimizing wear on the control system.
