Omega Engineering SSR240DC25 Solid State Relay

The Omega Engineering SSR240DC25 is a solid-state relay that switches 110–120 V AC loads up to 25 A when driven by a DC control signal in the 3–32 V range, a configuration identified by the model number SSR240DC25. This device serves as a direct interface between low-voltage control logic and mains-powered equipment, enabling rapid, silent switching of AC circuits in control panels and automation applications. Key electrical characteristics provided by Omega include 3–32 V DC input control and 110–120 V AC output with a maximum current of 25 A, giving you a clear, documented voltage range and current capacity for design and safety calculations. Designed for use in a variety of automation applications, the SSR240DC25 offers a compact, robust solution for converting a DC control signal into AC switching without mechanical contacts. Because the input is DC and the output is AC, it is well-suited for control from microcontrollers, PLCs, or other automation systems that provide a 3–32 V DC control signal to switch 110–120 V AC loads.
