Wago 857-718 is a Solid State Relay (SSR) designed for plug-in input with push-in CAGE CLAMP spring connections. It features a pre-assembled socket base, a yellow LED indicator, and supports a 2-wire connection with zero-cross switching. This SSR is rated for a continuous current of 2A and operates within a supply voltage range of 200-253Vdc (230Vdc nominal) for control, with an output rated impulse voltage of 24Vac-240Vac (230Vac nominal). It is designed for single-pole / single-phase / 1-pole (1P) applications and offers a response time of 10ms for both switching ON and OFF. The unit is compatible with a DIN-35 rail for mounting, has dimensions of H94mm x W6mm x D81mm, and is designed to operate in ambient air temperatures ranging from -20°C to +60°C, with storage temperatures from -40°C to +70°C. The SSR is protected to IP20 standards and is suitable for environments with 5-85% relative humidity, without condensation.
