Siemens AG Monitor - Relay Output 3UG46212AA30

The 3UG4621-2AA30 is a digital current monitoring relay for AC/DC currents from 3 mA to 600 mA, with adjustable trip levels from 3 mA to 500 mA and hysteresis from 0.1 mA to 250 mA. It operates on 24 V AC/DC (20.4-26.4 V), has a single change-over contact rated at 3 A at 250 V AC-15 and 1 A at 24 V DC-13, and offers adjustable delay times of 0.1 to 20 s. The relay includes an LCD display, automatic or external reset, and spring-loaded terminals for 0.25-1.5 mm² conductors. It is mounted in a 22.5 mm wide snap-on housing, has IP20 protection, and operates from -25 °C to +60 °C. Insulation voltage is 690 V per IEC 60664, with galvanic isolation between input and output. Mechanical life is 10 million cycles, electrical endurance is 100,000 cycles at AC-15.
