The 240D45-17 is a Power Series solid-state relay for switching 240 VAC, 45 A loads using a DC control signal. It operates with a control voltage range of 3 to 32 VDC and switches an AC operating voltage range of 24–280 VAC. This relay features 4,000 VRMS of optical isolation, a peak repetitive voltage of 600V, and can handle a 1-cycle peak surge current of 650 A. With its rugged epoxy encapsulation and zero-voltage turn-on, this SSR is well-suited for reliable switching in demanding industrial automation, process control, and high-power applications.
