Solid State Relay
A Solid State Relay (SSR) is generally used to switch On or Off a high voltage circuit by employing low voltage at its control terminals. SSR controls input to output actions for isolation and switching using the electrical and optical properties of solid-state semiconductors rather than a moving component to complete the circuit. It is an electronic switching device made of semiconductors with no movable parts. Due to no moving components, it is a Solid State Relay, and thus does not undergo any wear and tear on contact, making it long lasting for up to 100 million operations. What does Solid State Relay do? The major function is to switch “ON” or “OFF” and control a high voltage load. It provides complete electrical isolation between their input and output contacts. Solid State relays control the power using a relatively low voltage input. How does a Solid State Relay work? 1. Solid State Relay input circuit: The input circuit is responsible for relaying the signal to the
