788-549 WAGO Signal Relays

Wago 788-549 is a plug-in relay assembly featuring push-in CAGE CLAMP spring connections. It is designed for a rated current of 8A continuous, with specific ratings for AC and DC applications including 1.5A at 240Vac (AC-15), 1A at 24Vdc (DC-13), and has an inrush maximum current of 16A for 20ms / 12A for 4s AC. The relay offers socket base contacts, a red LED indicator, and an electromechanical design. It recommends a minimum switching load of 12V / 10mA. The relay has 2C/O / DPDT (Double Pole Double Throw) contact resistance, and it is suitable for ambient air temperatures ranging from -40°C to +70°C for storage. It provides a degree of protection rated at IP20 and is designed for a control voltage and rated voltage in AC within the same temperature range. The relay supports a communication protocol rated at C, with a rated impulse voltage (Uimp) of 4 kV. It is designed for mounting on a DIN-35 rail within a compact size of H86mm x W15mm x D73mm, and it features Silver-Nickel (AgNi) contacts. The rated operating voltage (Ue) is suitable for up to 250Vac max. switching voltage, with a power consumption between 0.9 to 1.1 times Uc at a nominal 230Vac. The relay's performance is specified for 10,000 operations at rated voltage (AC) - Phase-to-neutral and has a mechanical endurance of 5,000,000 operations.
