The 0 to 60 V adjustable voltage range matches common 24 V and 48 V DC control buses. The PROFINET IO interface (conformity class A) allows direct integration into a Siemens S7-1500 or other PROFINET controller without an extra analog input module — the relay reports current and voltage values digitally, and the trip thresholds are set via the controller or the device's own adjustable time delay (0 to 999 s on start-up). The auxiliary contact rating (0.5 A at 125 V AC, resistive load up to 40 °C) is sufficient for signaling to a PLC input or a pilot light, but not for switching a contactor coil directly — use an interposing relay if the coil draw exceeds that. The 45 mm width (3 HP) fits standard enclosure space. Front face is IP20; terminals are IP00 — keep live parts behind a panel door. Power loss is 3 W maximum, so no forced cooling needed in a typical cabinet.","metaTitle":"Siemens 3UG5462-1AA41 SIRIUS DC Load Monitoring Relay, -63…+","metaDescription":"Siemens SIRIUS 3UG5462-1AA41 DC load monitoring relay, PROFINET IO, measures -63…+63 A, 0…60 V.
