788-344 WAGO Signal Relays

WAGO 788-344 is an automation part designed for use in control circuits with a nominal input voltage of DC 110V and an input voltage range of +/-10%. It requires a nominal input current at UN of 4mA. The load circuit features one changeover/switchover contact made from AgNi material, with a limiting continuous current of 16A and an inrush current maximum of 32A (AC) for 0.02 seconds or 24A (AC) for 4 seconds. The maximum switching voltage is AC 250V, with a maximum resistive switching power of AC 4000 VA. The switching capacity is rated at 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 at 23°C for normally open resistive loads and a mechanical life of 5,000,000 switching operations. The maximum switching frequency with/without load is 6 min^-1 / 300 min^-1. It includes a red LED and mechanical status indicator. The rated voltage for safety and protection is 250V, with a rated surge voltage of 4kV and a pollution degree of 3. The dielectric strength between control and load circuit is 5kVrms, and across open contacts is 1kVrms. 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 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 / 0.35 to 0.39". The physical 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. The fire load is 0.696MJ, and it weighs 47.6g. It operates within an ambient temperature range of -40 to +70°C, with a UL-rated operational temperature range of -40 to +50°C and a storage temperature range of -40 to +70°C. The processing temperature range is -25 to +50°C, and the temperature range of the connection cable should be greater than the ambient temperature plus 20K. It meets standards and specifications such as EN 61010-2-201, EN 61810-1, EN 61373, and UL 508 (max. 10 A). It belongs to product group 6 (INTERFACE ELECTRONIC) and is compliant with RoHS. The packaging unit is 15 pieces per box, with the country of origin being Germany and a GTIN of 4050821226901. The customs tariff number is 85364900990.
