Solid-state relay module; Nominal input voltage: 24 VDC; Output voltage range: 0
30 VDC; Limiting continuous current: 8 A; Module width: 6 mm.
The WAGO 857 series plug-in input solid-state relay (SSR) features a pre-assembled socket base and a yellow LED indicator. It supports a 2-wire connection and is designed for single-pole, single-phase applications with a control voltage range of 16.8-30Vdc (24Vdc nominal). The relay has a rated output voltage of 1Vdc-30Vdc (24Vdc nominal) and can handle a continuous current of 8A. It includes Push-in CAGE CLAMP connections for easy installation and is mounted on a DIN-35 rail with a 6mm width. The device has an IP20 protection rating and is equivalent to model 857734.
