859-390 WAGO Signal Relays

Wago 859-390 is a fixed-type relay module designed for railway applications with an electromechanical design. It features CAGE-CLAMP spring connections for secure and maintenance-free wiring and is equipped with a red LED for status indication. This relay supports a rated current of 5A (continuous) and operates with a single-pole double throw (SPDT) contact configuration. The recommended minimum switching load is 10V / 10mA / 24V / 1mA, and it can handle a supply voltage up to 250Vac max. (switching voltage) with a control voltage range of 16.8-30Vdc (24Vdc nominal). The rated impulse voltage (Uimp) ranges from 0.7 to 1.25 times the control voltage, and the rated insulation voltage (Ui) is 4 kV. It is designed for use in environments with ambient air temperatures for operation and storage ranging from -40°C to +70°C. The relay's dimensions are H91mm x W6mm x D56mm, with a width of 6mm, making it suitable for DIN-35 rail mounting. The contacts are made of Silver-Tin (AgSnO) to ensure durability, with a short circuit breaking rating and a rated operating voltage (Ue) of 250 V. It has a switching speed with contacts closing in 15ms and opening in 25ms, designed for up to 5 000 000 operations, and can withstand 5-95% relative humidity without condensation.
