788-349 WAGO Signal Relays

WAGO 788-349 is a relay module designed for automation applications, featuring a nominal input voltage of DC 110V with an input voltage range of +/-10% and a nominal input current at UN of 4mA. It includes two changeover/switchover contacts made from AgNi material, with a limiting continuous current of 8A and an inrush current capacity of up to 16A for resistive loads over 0.02 seconds or 12A over 4 seconds. The module supports a maximum switching voltage of AC 250V and a maximum resistive switching power of AC 2000 VA, with specific switching capacities for AC-15 and DC-13 applications. It has a pull-in time of 15ms, a drop-out time of 8ms, and a bounce time of 7ms. The electrical life is rated at 10,000 switching operations at 23°C for normally open resistive loads, and the mechanical life is rated at 5 million switching operations. The switching frequency can reach up to 6 min^-1 with load and 300 min^-1 without load. It features a red LED and mechanical status indicator, with a rated voltage of 250V, surge voltage rating of 4kV, and a pollution degree of 3. The dielectric strength is 5kVrms between control and load circuits, 1kVrms across open contacts, and 2.5kVrms between load circuits. It requires a separator plate for voltages greater than 250V between adjacent relay modules for reinforced insulation compliance. The protection type is IP20, and it utilizes push-in CAGE CLAMP connection technology for solid and fine-stranded conductors ranging from 0.34 to 2.5mm2 (22 to 14 AWG) with a strip length of 9 to 10mm. The module's dimensions are 15mm in width, 86mm in height, and 73mm in depth from the upper edge of the DIN-rail, designed for mounting on a DIN-35 rail. It has a fire load of 0.696MJ and weighs 48.6g. The operational ambient temperature range is -40 to +70°C, with a storage temperature range matching the operational range. It meets EN 61010-2-201, EN 61810-1, EN 61373, and UL 508 standards and specifications. The product belongs to INTERFACE ELECTRONIC Group 6, with RoHS compliance and no exemptions. It is packaged in boxes of 15 pieces, with a country of origin in Germany and a GTIN of 4050821226833.
