288-504 WAGO Signal Relays

Wago 288-504 is a plug-in relay assembly featuring CAGE-CLAMP spring connections for secure and maintenance-free connections. It is designed with a socket base and an electromechanical design, incorporating a 1C/O / SPDT (Single Pole Double Throw) contact configuration. This relay supports a rated current of 6A for continuous operation and can handle up to 16A AC inrush maximum current for 4 seconds. It operates within an ambient air temperature range for operation of -25°C to +40°C and has a storage temperature range of -40°C to +80°C. The control voltage ranges from 21.6-26.4Vdc (24Vdc nominal) for DC and 21.6-26.4Vac (24Vac nominal) for AC, with a rated impulse voltage (Uimp) of 0.9...1.1 x Uc. The relay's dimensions are H85mm x W20.5mm x D48mm, fitting a DIN-35 rail for mounting. It features Silver-Nickel (AgNi 90/10) contacts for durability and has a rated insulation voltage (Ui) of 2.5 kV. The switching voltage is capped at 250Vac max, and it is designed for a rated operating voltage (Ue) of 250 V. The relay boasts a mechanical life of 30,000,000 operations and an electrical life of 100,000 operations, with power dissipation/losses rated at 0.9...1.1 x Uc.
