859-307 WAGO Signal Relays

Wago 859-307 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 5A continuously and can support up to 20A AC inrush maximum current for 20ms. The module is equipped with a red LED for status indication and operates based on an electromechanical design. It recommends a minimum switching load of 20V / 10mA / 24V / 1mA. The relay provides a 1C/O / SPDT (Single Pole Double Throw) contact configuration. It is designed to operate within an ambient air temperature range of -40°C to +50°C and can be stored in temperatures ranging from -40°C to +70°C. The control voltage ranges from 93.5-132Vdc (110Vdc nominal), with a maximum switching voltage of 250Vac and a rated insulation voltage (Ui) of 4 kV. The relay is suitable for mounting on a DIN-35 rail, with dimensions of H91mm x W6mm x D56mm and a width of 6mm. It features Silver-Tin (AgSnO) contacts for the short circuit breaking rating. The relay's operating times are 15ms for contacts closing and 25ms for contacts opening, with a rated operating voltage (Ue) of 250 V. It is designed for up to 50,000 operations for Normally Closed (NC) circuits and has a mechanical endurance of 5,000,000 operations. The relay can operate in environments with 5-95% relative humidity, without condensation.
