It detects both overvoltage and undervoltage conditions, with a relative repeat accuracy of 1 %, and offers an IO-Link interface at COM2 (38.4 kBaud) for parameterization and diagnostics. The relay supports automatic and external reset, and includes a configurable start-up delay (0 to 999.9 s) to ride through transient dips. Housed in a 22.5 mm wide enclosure (92 mm height, 91 mm depth), it snaps onto a DIN rail in any orientation — zero clearance required on all sides. Rated IP20, pollution degree 2, and operates from -25 °C to +60 °C; storage and transport range extends to -40 °C to +85 °C. For BOM freeze or project planning, the IO-Link capability and wide voltage range make it a stable choice for new panel designs requiring over/undervoltage monitoring.","metaTitle":"Siemens 3UG4832-1AA40 SIRIUS Voltage Monitoring Relay, 10-60","metaDescription":"Siemens SIRIUS 3UG4832-1AA40 voltage monitoring relay, 10-600 V AC/DC, over/undervoltage detection, IO-Link, LCD display, IP20, current production.
