What are plugin relays or general purpose relays and what is its significance in control panels and switchgear?

Plugin relays, also known as plug-in relays or relay modules, are electrical devices used in control panels and switchgear to control the flow of electrical current in various industrial and commercial applications. They play a crucial role in automation, electrical control systems, and process control. Here’s an overview of plugin relays and their significance in control panels and switchgear: Plugin relays are designed to be mounted on relay sockets or bases, making them easily replaceable and maintainable. These sockets typically feature standard connectors, allowing for quick installation and removal of the relay.

Application of Plugin relays:

  • Switching and Control
  • Signal Conditioning
  • Protection
  • Logic Function
  • Fault Protection
