The Siemens 3RP1540-2AN31 is a SIRIUS time relay with an adjustable timing range of 0.05 to 600 seconds, powered by a 200–240 VAC/DC control supply. The relay output switches at 1 A at 24 V, 0.2 A at 125 V, or 0.1 A at 250 V, so it handles pilot-duty signalling loads rather than direct motor switching.
Basic insulation and pollution degree 3 suit it for industrial control panels without special isolation barriers.
The adjustable time range is 0.05 to 600 seconds, set via the front dial.
The control supply voltage is 200–240 V, accepting both AC (50/60 Hz) and DC.
