788-391 WAGO Signal Relays

WAGO 788-391 is a relay module designed for automation applications, featuring a nominal input voltage of DC 24V with an input voltage range of -30...+25%. It has a nominal input current at UN of 20mA and one changeover/switchover contact made from AgNi material. The limiting continuous current is 16A, with an inrush current (resistive) maximum of (AC) 32A / 0.02 s and (AC) 24A / 4s. The maximum switching voltage is AC 250V, with a maximum resistive switching power of AC 4000 VA and DC as per the load limit curve. It offers a switching capacity of AC-15 3A / AC 240 V and DC-13 2A / DC 24V, with a recommended minimum load of 12V / 10mA. The pull-in time is typically 15ms, drop-out time 8ms, and bounce time 6ms. It has an electrical life of 10,000 switching operations (NO; resistive load; 23°C) and a mechanical life of 5,000,000 switching operations. The switching frequency with/without load (max.) is 6 min^-1 / 300 min^-1. It includes a red LED status indicator. Rated at 250V with a rated surge voltage of 4kV and a pollution degree of 3, it has a dielectric strength of 5kVrms (control/load circuit) and 1kVrms (open contact) for 1 minute. It requires a separator plate for voltages greater than 250V between adjacent relay modules for reinforced insulation compliance. The protection type is IP20. Connection is facilitated through Push-in CAGE CLAMP for solid and fine-stranded conductors ranging from 0.34...2.5mm2 / 22...14 AWG with a strip length of 9...10mm / 0.35...0.39". The module dimensions are 15mm in width, 86mm in height, and 73mm in depth from the upper edge of the DIN-rail, designed for DIN-35 rail mounting. It has a fire load of 0.696MJ and weighs 45g. The operational and storage ambient temperature ranges are -40...+70°C, with a processing temperature range of -25...+50°C. It complies with EN 61010-2-201, EN 61810-1, and EN 61373 standards. The product belongs to Group 6 (INTERFACE ELECTRONIC), with eClass 10.0 and 9.0 classifications of 27-37-16-01, and ETIM 8.0 and 7.0 classifications of EC001437. Packaged in boxes, each unit contains 15 pieces, with a country of origin in DE and a GTIN of 4050821128731. The customs tariff number is 85364900990, and it is RoHS compliant without exemptions.
