Electromechanical relay (EMR) is one of the oldest and still most widely used switching devices in electronics and electrical engineering. A relay is an electromechanical switching component that uses an electromagnet to mechanically operate a set of contacts. In simple words, a relay uses a small control signal (low power side) to switch large loads […]
A Solid-State Relay (SSR) is an electronic switching device that performs the same function as an electromechanical relay (EMR) but without any moving parts. Instead of mechanical contacts, it uses semiconductor devices such as thyristors, Triacs, MOSFETs, or transistors to switch electrical loads ON or OFF. Because there are no moving parts, SSRs offer longer […]
