788-342 WAGO Signal Relays

WAGO 788-342 is an automation part designed for use in control circuits with a nominal input voltage of DC 48V and an input voltage range of +/-10%. It features a nominal input current at UN of 9mA and one changeover/switchover contact made from AgNi material. The part supports a limiting continuous current of 16A and can handle inrush currents of up to 32A for 0.02 seconds and 24A for 4 seconds in AC. Its 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 for AC and DC-13 2A / DC 24V for DC, 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 and a mechanical life of 5,000,000 switching operations at 23°C. The switching frequency with and without load is a maximum of 6 min^-1 and 300 min^-1, respectively. It includes a red LED and mechanical status indicator, with a rated voltage of 250V, rated surge voltage of 4kV, and a pollution degree of 3. The dielectric strength between control and load circuit is 5kVrms, and 1kVrms across open contacts. It meets reinforced insulation requirements with the use of a separator plate for voltages greater than 250V between adjacent relay modules. 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 50g. It operates within an ambient temperature range of -40 to +70°C, with a storage temperature range identical to its operational range. It complies with EN 61010-2-201, EN 61810-1, EN 61373, and UL 508 (max. 10 A) standards and specifications. The product belongs to Group 6 (INTERFACE ELECTRONIC) and is RoHS compliant without exemptions. It is packaged in boxes of 15 pieces, with a country of origin in DE and a GTIN of 4050821226796.
