The PLC-RSP-72UC/21-21AU/RW is a relay module for railway applications with a spring-cage connection and two changeover contacts featuring multi-layer gold-plated switches. It operates on 72 V DC with an input range of 50.4 V to 90 V DC, and meets EN 50155 for vibration, shock, and temperature class TX (-40°C to +70°C). The module has 5 kV isolation between coil and contacts, a rated insulation voltage of 250 V AC, and a surge voltage rating of 6 kV. Maximum switching capacity is 50 mA for gold contact operation, rising to 6 A when the gold layer is compromised, with interrupting ratings up to 1500 VA at 250 V AC. It includes an RCZ surge filter and a yellow LED for voltage indication. Weight is 35.8 g without packing.
