Product Introduction
Solid State Relays (SSRs) are optically isolated electronic switching devices that turn on or off when a small voltage is applied across the control input terminals. SR is similar to bases, DIN rails, receptacles, and board-mounted electromechanical relays designed to switch AC or DC loads up to 660 V due to semiconductors and no moving parts. These devices can be selected based on load voltage, rated current, and switching circuit configurations such as SPST, SPDTDPST, and 3PST.
