859-302 WAGO Signal Relays

Wago 859-302 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 manage 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 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 4.25-6Vdc (5Vdc nominal), with a rated impulse voltage (Uimp) of 0.85...1.2 x Uc. The module's dimensions are H91mm x W6mm x D56mm, fitting a 6mm width on a DIN-35 rail for mounting. It features Silver-Tin (AgSnO) contacts for the switching mechanism, with a rated insulation voltage (Ui) of 4 kV and a switching voltage capacity of 250Vac max. The relay operates with a control voltage for AC circuits being single-pole / 1-pole (1P) and has a power consumption tailored for DIN-35 rail mounting. The relay's performance is characterized by a switching time of 15ms for contacts closing and 25ms for contacts opening, with a rated operating voltage (Ue) of 250 V. It is designed for a high number of operations, offering 50,000 operations for Normally Closed (NC) circuits and a mechanical life of 5,000,000 operations. The relay can operate within a humidity range of 5-95% RH, with no condensation permissible.
