788-312/003-000 WAGO Signal Relays

WAGO 788-312/003-000 is an automation part designed for use in control circuits with a nominal input voltage of DC 24V and an input voltage range of -25...+30%. It has a nominal input current at UN of 19mA. The load circuit features 2 changeover/switchover contacts, with contact material made of AgNi 90/10, and a limiting continuous current of 8A. The inrush current for resistive loads is max. (AC) 15A / 4s, with a maximum switching voltage of AC 250V and a maximum resistive switching power of AC 2000 VA; for DC, refer to the load limit curve. The switching capacity is AC-15 3A / AC 250 V; DC-13 2A / DC 24V, with a recommended minimum load of 12V / 10mA. The pull-in time is typically 7ms, drop-out time 2ms, and bounce time 3ms. The electrical life for normally open, resistive load at 23°C is 1,000 switching operations, and the mechanical life is 30,000,000 switching operations. The maximum switching frequency with/without load is 6 min^-1 / 1200 min^-1. It includes a red LED status indicator. Rated voltage is 250V, with a rated surge voltage of 4kV and a pollution degree of 3. Dielectric strength is 5kVrms (control/load circuit), 1kVrms (open contact), and 2.5kVrms (load/load circuit). It requires a separator plate for voltages greater than 250V between adjacent relay modules for reinforced insulation compliance. Protection type is IP20. Connection technology is Push-in CAGE CLAMP, accommodating solid and fine-stranded conductors of 0.34...2.5mm2 / 22...14 AWG with a strip length of 9...10mm / 0.35...0.39". Physical dimensions are 15mm width, 86mm height, and 54mm depth from the upper edge of DIN-rail, designed for DIN-35 rail mounting. The fire load is 1.372MJ, and the weight is 46.2g. It operates in ambient temperatures of -40...+50°C and can be stored in temperatures of -40...+70°C. It complies with standards EN 61010-2-201, EN 61810-1, EN 61373, UL 508, and DNV. The product belongs to Group 6 (INTERFACE ELECTRONIC), with eClass 10.0 and 9.0 classification of 27-37-16-01, and ETIM 8.0 and 7.0 classification of EC001437. Packaged in boxes, with a country of origin DE, GTIN 4045454606930, and customs tariff number 85364900990. It meets environmental product compliance including RoHS with exemptions, and has SCIP notification numbers for multiple countries.
