Siemens AG Monitor - Relay Output 3UG46312AA30

The 3UG4631-2AA30 is a digital voltage monitoring relay for AC/DC supply voltages from 0.1 to 60 V, with a 24 V AC/DC control supply. It features a single change-over contact, adjustable response delay from 0.1 to 20 s, and hysteresis from 0.1 to 30 V. The relay has an LCD display, spring-type terminals, and supports snap-on mounting. It measures 22.5 mm wide, 94 mm high, and 91 mm deep, with an IP20 protection rating. The device operates from -25 °C to +60 °C and meets IEC 60664 insulation requirements for overvoltage category III. Galvanic isolation exists between input and output, but not between control supply and other circuits. It complies with IEC 61000-4-2, -4-3, -4-4, and -4-5 for electromagnetic compatibility.
