859-357 WAGO Signal Relays

Wago 859-357 is a fixed-type relay module featuring CAGE-CLAMP spring connections for secure and maintenance-free connections. 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 on an electromechanical design. It recommends a minimum switching load of 10V / 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 97.75-126.5Vdc (115Vdc nominal) for DC and 97.75-126.5Vac (115Vac nominal) for AC, with a power consumption of 0.85...1.1 x Uc. The module's dimensions are H91mm x W6mm x D56mm, fitting a DIN-35 rail for mounting. It features Silver-Tin (AgSnO) contacts for reliable connectivity. The rated operating voltage (Ue) is marked by a switching speed of 15ms for contacts closing and 25ms for contacts opening. The relay is capable of 50,000 operations phase-to-phase at a rated voltage (AC) and has a power dissipation/losses capacity of 5,000,000 operations. It is designed to work within a humidity range of 5-95% RH, with no condensation permissible.
