858-508 WAGO Signal Relays

Wago 858-508 is a plug-in relay assembly featuring push-in CAGE CLAMP spring connections. It is designed to handle a rated current of 5A continuously, with specific ratings for AC and DC applications including 1A at 240Vac (AC-15), 2A at 24Vdc (DC-13), and a 15A AC inrush maximum current. The relay offers a 4C/O or 4PDT (4 Pole Double Throw) contact resistance and is equipped with a socket base, a red LED, and an electromechanical design. It recommends a minimum switching load of 12V / 100mA. The relay operates within an ambient air temperature range for storage of -25°C to +70°C and offers a degree of protection rated at IP20. It supports a control voltage (DC) of -40°C to +80°C, with a rated impulse voltage (Uimp) of 2.5 kV. The relay is designed for mounting on a DIN-35 rail and has dimensions of 97mm in height, 31mm in width, and 73mm in depth. It features silver-cerium (AgCe) contacts and has a power consumption range of 0.8 to 1.1 times the control voltage (Uc) at a nominal 230Vac. The relay's rated operating voltage (Ue) supports up to 250Vac maximum switching voltage, with a primary current sensing distance for contacts closing and opening specified as 25ms and 35ms, respectively. It is rated for 100,000 operations at rated voltage (AC) phase-to-neutral and has a trip current rating of 20,000,000 operations. The relay can accommodate a humidity range of 5-85% relative humidity (RH).
