The WAGO 858 series plug-in relay assembly features a socket base, manual operation, and a red LED indicator. It is a 4-pole (4P) relay with a control voltage range of 19.2-26.4Vdc (nominal 24Vdc) and a 4C/O (4 Pole Double Throw) contact configuration. The electromechanical design supports a rated current of 50mA at 30Vdc (DC-13), with Push-in CAGE CLAMP connections for easy installation on a DIN-35 rail (31mm width). The relay has an IP20 protection rating and uses hard gold-plated silver-cerium (AgCe + Au) contacts to prevent gold flash evaporation, equivalent to model 858314.
