Timer relay module; Nominal input voltage: 24 VDC; Limiting continuous current: 6 A; Railway; Multifunction; Yellow status indicator; Module width: 6 mm; gray.
The WAGO 857 series timing relay assembly features ON-delay switching, a socket base with an ejector, and a yellow LED, designed for railway applications. It is a single-pole (1P) device with a control voltage range of 16.8-31.2Vdc (24Vdc nominal; 0.7...1.3 x Uc) and a Single Pole Double Throw (SPDT) contact configuration. The electromechanical relay has a rated current of 6A continuous, 3A at 250Vac (AC-15), and 2A at 24Vdc (DC-13). It includes Push-in CAGE CLAMP connections and is mounted on a DIN-35 rail with a 6mm width. The relay has an IP20 protection rating and uses Silver-Tin (AgSnO) contacts, equivalent to model 857604.
