Dayton 1EJK7 Solid State Relay

The Dayton 1EJK7 Solid State Relay is a compact SPST device designed to switch AC loads in control panels, automation equipment, and other electrical enclosures where quiet, rapid switching is preferred over mechanical relays. The input side is specified for 90–280 VAC, which energizes the device to close the circuit on the output side, while the output side is rated to switch 48–600 VAC at up to 10 A, providing a single switching path for AC circuits. Because it contains no moving parts, the 1EJK7 avoids the wear, arcing, and audible noise associated with electromechanical relays, making it well-suited for frequent switching and environments where long life and low maintenance are priorities. When selecting this model, verify that both the input control voltage and the load voltage/current fall within the specified ranges, and plan for heat management if operating near the 10 A limit.
