288-304 WAGO Signal Relays

Wago 288-304 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. This relay supports a rated current of 6A continuous and can handle up to 16A AC inrush maximum current for 4 seconds. It operates within an ambient air temperature range of -25°C to +40°C and can be stored in temperatures ranging from -40°C to +80°C. The control voltage ranges from 21.6 to 26.4Vdc (24Vdc nominal), with a rated impulse voltage (Uimp) of 0.9 to 1.1 times the control voltage. The net dimensions are specified as H85mm x W20.5mm x D48mm, with a width of 20.5mm. It features silver-nickel (AgNi 90/10) contacts for the switching elements, ensuring a short circuit breaking rating. The relay's operating speed for contacts closing is 9ms and for contacts opening is 3ms. It has a rated insulation voltage (Ui) of 4 kV and a switching voltage maximum of 250Vac. Designed for mounting on a DIN-35 rail, it includes normally closed (NC) auxiliary contacts. The relay is capable of 100,000 operations for normally closed circuits and has a durability of 30,000,000 operations overall. It operates efficiently within a humidity range of 5-75% RH, non-condensing.
