Multifunction timing relay with 1 changeover contact (1u); 8 tiem ranges; 7 functions; 2 adjustable time ranges; Temperature range: -25 C ... +70 C; for railway operations
- 7 functions
- 2 separately adjustable time ranges
- Function and time range adjustable via DIP switch
The WAGO 857 series fixed-type timing relay module is designed for railway applications and features ON- and OFF-delay switching with two separate adjustable time ranges. It includes a yellow LED indicator and operates with a control voltage range of 16.8-31.2Vdc (24Vdc nominal). The module has a single-pole, single-pole double throw (SPDT) contact configuration with an electromechanical design, supporting a rated current of 6A continuous, 3A at 250Vac (AC-15), and 2A at 24Vdc (DC-13). It utilizes Push-in CAGE CLAMP connections and is mounted on a DIN-35 rail with a 6mm width. The relay has IP20 protection and features Silver-Tin (AgSnO) contacts, equivalent to model 857642.
