858-324 WAGO Signal Relays

Wago 858-324 is a plug-in relay assembly featuring push-in CAGE CLAMP spring connections. It is designed with a rated current of 12A for continuous operation, 1.5A at 250Vac (AC-15), and 0.1A at 24Vdc (DC-13), with a maximum inrush current of 24A for 4 seconds in AC. The relay includes a socket base, a red LED indicator, and operates on an electromechanical design. It recommends a minimum switching load of 10V / 5mA / 300mW. The relay has 2C/O or DPDT (Double Pole Double Throw) contact resistance, and it is suitable for ambient air temperatures ranging from -40°C to +55°C for storage and -40°C to +85°C for operation. It features a degree of protection rated at IP20 and has a net width of 19.2-26.4Vdc (24Vdc nominal) with a control voltage range of 0.8 to 1.1 times Uc. The relay is designed for a 250Vac maximum switching voltage, with a control voltage (AC) of 2.5kV and a rated active power for 2-poles (2P). It can be mounted on a DIN-35 rail and has dimensions of H97mm x W31mm x D73mm, with a width of 31mm. The contacts are made of Silver-Nickel (AgNi), and the rated operating voltage (Ue) for the relay is specified for both ON to OFF and OFF to ON transitions, with respective times of 13ms and 3ms. The relay is rated for 250V, with a phase-to-neutral rated voltage (AC), capable of 100,000 operations for primary current and 20,000,000 operations for trip current rating. It can accommodate a humidity range of 5-85% relative humidity (RH).
