The Siemens 3RP1505-1BW30 is a SIRIUS timing relay that gives you both ON-delay and OFF-delay in one 22.5 mm wide package, adjustable from 0.05 to 100 seconds. Contact rating is 1 A at 24 V, 0.2 A at 125 V, 0.1 A at 250 V, with a thermal current of 5 A — sized for signal-level switching, not motor loads.
Mounts on 35 mm DIN rail with screw and snap-on fastening — no tools needed for the snap, but the screw terminals need 0.8–1.2 N·m torque. Accepts 20–14 AWG stranded or solid wire. Any mounting position works, and the 91 mm depth leaves room in a standard 120 mm enclosure.
