Relays serve as switches that can control circuits remotely by using an electrical signal to open or close the contacts within a circuit. They are vital in controlling high-power devices with low-power control signals, providing an essential role in electrical protection, automation, and system control. Given the critical role they play in managing and safeguarding systems, ensuring the proper functionality of relays through rigorous testing is of paramount importance. Relay failure can lead to significant disruptions, safety hazards, or even equipment damage, making testing a crucial step in preventing costly mistakes and potential accidents.
