859-359 WAGO Signal Relays

Wago 859-359 is a fixed-type relay module featuring CAGE-CLAMP spring connections for secure and maintenance-free wiring. It is designed to handle a rated current of 50mA at 30Vdc (DC-13) for maximum recommended current to avoid evaporating the Gold flash, 5A continuously, and up to 20A for 20ms AC inrush maximum current. This module is equipped with Normally Open (NO) auxiliary contacts indicated by a red LED and operates on an electromechanical design. It supports a minimum switching load of 1V / 1mA / 1mA and offers a rated power for 1C/O / SPDT (Single Pole Double Throw) contact. The relay operates efficiently within an ambient air temperature range of -40°C to +50°C for operation and -40°C to +70°C for storage. It is rated for a control voltage of 195.5-253Vdc (230Vdc nominal) and a rated impulse voltage (Uimp) of 4 kV. The module's dimensions are specified as H91mm x W6mm x D56mm, with a net width of 6mm, making it suitable for mounting on a DIN-35 rail. The contacts are made of Hard Gold-plated Silver-Nickel (AgNi + Au) to ensure durability and reliable connectivity. The rated operating voltage (Ue) is 250Vac max., with a primary current sensing speed of 15ms for contacts closing and 30ms for contacts opening. It is designed for a high number of operations, with 50,000 for phase-to-neutral and 5,000,000 operations overall, under conditions of 5-95% relative humidity without condensation.
