Siemens AG Monitor - Relay Output 3UG46312AW30

The 3UG4631-2AW30 is a digital voltage monitoring relay for AC/DC systems, detecting overvoltage and undervoltage from 0.1 to 60 V with adjustable delays of 0.1 to 20 s. It has a single change-over contact rated for 5 A continuous current and operates from a 24 to 240 V AC/DC control supply. Mounted via snap-on rail, it measures 22.5 mm wide, 94 mm high, and 91 mm deep, with spring terminals for 0.25 to 1.5 mm² conductors. It meets IP20 protection, operates from -25 to +60 °C, and withstands 4 kV surge voltage. Galvanic isolation is provided between input, output, and supply circuits. Electrical endurance is 100,000 switching cycles at AC-15, and relative measurement accuracy is ±1 digit.
