The Siemens 3UG3531-1AL20 is a SIRIUS monitoring relay in a 22.5 mm housing, measuring voltage from 0.2 to 60 V AC/DC with adjustable threshold and hysteresis.
For existing BOM lines or installed panels, the 3UG3531-1AL20 can still be sourced through independent channels on a quoted-to-order basis. No last-time-buy window remains open from Siemens.
Siemens specifies 3UG4631-1AW30 as the direct replacement. It shares the 22.5 mm width, 0.2...60 V AC/DC measurement range, 1CO output, and screw-terminal connection.
Measuring voltage 0.2...60 V AC/DC, one changeover contact rated 230 V AC 50/60 Hz, 22.5 mm housing, IP20, snap-on DIN-rail mount, screw terminals.
