Relay module; Nominal input voltage: 24 VDC; 1 changeover contact; Limiting continuous current: 6 A; with gold contacts; Yellow status indicator; Module width: 6 mm; 2,50 mm²; gray.
The WAGO 857 series plug-in relay assembly features a single-pole, single-throw (SPDT) contact with a control voltage range of 20.4-28.8Vdc and a nominal voltage of 24Vdc. It has an electromechanical design with a rated current of 50mA at 30Vdc, utilizing Push-in CAGE CLAMP connections for easy installation on a DIN-35 rail. The relay includes a yellow LED indicator and an ejector, and it is constructed with hard gold-plated silver-nickel contacts to prevent gold flash evaporation. The assembly is IP20 rated and measures 6mm in width, equivalent to model 857314.
