Controlling Automation: The Critical Role of Relays in Industrial Systems
Category: Relays
In industrial automation, relays act as the silent controllers that bridge low-power control systems and high-power machinery. From switching circuits and activating motors to safeguarding systems from overload — relays are fundamental to ensuring that automated operations run safely, efficiently, and intelligently.

What Is a Relay?
A relay is an electromechanical or electronic device that uses a small electrical signal to control a larger one. It acts as a switch — opening or closing circuits automatically to manage power flow between control systems (like PLCs) and the equipment they operate.
In automation environments, relays are vital for controlling lights, motors, pumps, valves, and alarms, ensuring precise and safe operation under varying load conditions.
