The 3UG4822-1AA40: The relay operates on a 24 V DC supply (18–30 V DC range) and provides a repeat accuracy of 1 %, ensuring consistent trip points for process protection or load monitoring. The digital setting eliminates potentiometer drift over time, a common failure point in analog-adjustable relays.
Lifecycle and Sourcing Reality
The 3UG4822-1AA40 is a standard catalog item within the SIRIUS product family. Sourcing is straightforward — quoted to order against an RFQ. No last-time-buy or allocation constraints are indicated by the lifecycle data.
Mounting and Integration
The relay snaps onto a 35 mm DIN rail (snap-on mounting per the specification) and can be mounted in any position. Width is 22.5 mm, height 92 mm, depth 91 mm — a standard single-module footprint that fits alongside contactors, breakers, and PLC slices in a typical control panel. Terminals accept solid or stranded wire from 20 AWG to 14 AWG (2x conductors per terminal). Screw-type terminals for the main current circuit are standard. The relay offers both auto-reset and external reset capability, selectable via the digital interface or DIP settings.
