The Siemens 3RP1540-2BB31 is a SIRIUS timing relay with an adjustable time range of 0.05 to 600 s, a thermal current rating of 5 A, and a contact rating of 1 A at 24 V DC.
The adjustable time range covers 0.05 to 600 s, and the relay output is non-volatile, meaning the set delay is retained without a backup battery.
The timing relay has an adjustable time range of 0.05 to 600 s, a thermal current rating of 5 A, and a contact rating of 1 A at 24 V DC.
This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at the time of quote.
It mounts via screw and snap-on onto a 35 mm standard mounting rail, with a width of 22.5 mm.
