Product details

Timing Relay with OFF-Delay — SIRIUS 3RT1926-2DH21

The Siemens SIRIUS 3RT1926-2DH21 is a timing relay designed with OFF-delay, meaning the output remains energized for a set period after the control signal is removed — useful for sequenced shutdowns, post-lubrication runs, or delayed vent cycles. The adjustable time range spans 0.5 to 10 seconds, and the recovery time between cycles is 150 ms, so it can re-trigger quickly in a repeating sequence.

Clip-on fastening to standard DIN rail — snaps onto the rail without tools, and the 45 mm width occupies one standard modular device space.
