Solid state relay; Pluggable replacement optocoupler; 24 VDC.
The WAGO 857 series replacement plug-in solid-state relay (SSR) module is a single-pole, single-phase device designed for 2-wire connections. It operates with a control voltage range of 18.8-31.2Vdc (24Vdc nominal) and provides an output rated voltage of 0-30Vdc (24Vdc nominal) with a continuous rated current of 3A. The module features plug-in connections and mounting, and is equivalent to the 857161 model.
