It is designed for control circuits where a load must stay energised for a set period after the control signal drops out, typical in conveyor sequencing, pump run-on, or ventilation after-stop timing. The adjustable OFF-delay spans 0.05 … 1 s, set via a potentiometer or DIP switch (the evidence does not specify the adjustment method). The minimum ON period before the delay can start is 35 ms, and after the delay expires the relay needs 150 ms recovery time before it can trigger again — important for fast-cycling loads like short conveyor segments. Basic insulation per IEC 61812-1 and EMC immunity to EN 61000-6-2 confirm it meets the minimum isolation and noise-rejection requirements for industrial control circuits.","metaTitle":"Siemens 3RT1916-2DH11 SIRIUS Timing Relay, OFF-Delay, 0.05-1","metaDescription":"Siemens SIRIUS 3RT1916-2DH11 timing relay, OFF-delay, adjustable 0.05-1 s, 90-240 V AC/DC, clip-on mounting.
