788-347 WAGO Signal Relays

WAGO 788-347 is a relay module designed for automation applications, featuring a nominal input voltage of DC 48V with an input voltage range of +/-10% and a nominal input current at UN of 9mA. It includes two changeover/switchover contacts made from AgNi material, with a limiting continuous current of 8A and an inrush current capacity of 16A for 0.02 seconds and 12A for 4 seconds in AC. The maximum switching voltage is AC 250V, with a maximum resistive switching power of AC 2000 VA. The switching capacity is rated at AC-15 1.5A / AC 240 V and DC-13 1A / DC 24V, with a recommended minimum load of 12V / 10mA. The pull-in time is typically 15ms, drop-out time 8ms, and bounce time 7ms. It has an electrical life of 10,000 switching operations and a mechanical life of 5,000,000 switching operations at 23°C. The switching frequency with and without load is 6 min^-1 / 300 min^-1, respectively. It features a red LED and mechanical status indicator, with a rated voltage of 250V, surge voltage of 4kV, and 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. The protection type is IP20, utilizing 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 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 48.1g. It operates within an ambient temperature range of -40 to +70°C, with a storage temperature range identical to its operational range. The processing temperature range is -25 to +50°C, and it complies with EN 61010-2-201, EN 61810-1, EN 61373, and UL 508 standards. It is classified under Product 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. The packaging unit is 15 pieces per box, manufactured in Germany with a GTIN of 4050821226857 and a customs tariff number of 85364900990. It is RoHS compliant without exemptions.
