859-355 WAGO Signal Relays

Wago 859-355 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 manage 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 10V / 10mA / 24V / 1mA. The relay provides a 1C/O / SPDT (Single Pole Double Throw) contact configuration. It is suitable for operation in ambient air temperatures ranging from -40°C to +50°C and can be stored in temperatures from -40°C to +70°C. The control voltage ranges from 40.8-52.8Vdc (48Vdc nominal) for DC and 40.8-52.8Vac (48Vac nominal) for AC, with a power consumption of 0.85...1.1 x Uc. The module's dimensions are H91mm x W6mm x D56mm, and it is designed for mounting on a DIN-35 rail. It features Silver-Tin (AgSnO) contacts for reliable connectivity. The rated impulse voltage (Uimp) is between 0.85...1.1 x Uc, and the rated insulation voltage (Ui) is 4 kV. The switching voltage is capped at 250Vac max. The relay's operating and storage temperature, speed, degree of protection, and other specifications are tailored to ensure compatibility with a wide range of industrial applications. The product is designed for a high number of operations, with 50,000 phase-to-phase and 5,000,000 power dissipation/losses operations. It is recommended for use in environments with 5-95% relative humidity, with no condensation permissible.
