It is designed for control panel integration where a precise, repeatable delay is needed between a control signal and the start of a motor, valve, or other load. It is rated for basic insulation per pollution degree 3, meaning it is suitable for the typical industrial environment where conductive pollution may occur. The adjustable time range of 0.05 to 1 second is set via a potentiometer on the device face. The recovery time is 50 ms — this is the minimum interval after the output resets before a new timing cycle can begin. If your application requires a faster re-trigger, this part won't support it. The ON-delay function means the output contact closes only after the set time has elapsed following application of the control voltage. There is no OFF-delay, no pulse-shaping, and no instantaneous contact — it is a single-function timer. The initial value of 0.8 seconds is the factory-default time setting. If you are replacing an older timing relay with a different footprint, verify the 45 mm width and clip-on mounting match your existing DIN rail layout. ## Where this class of part is used The 90-240 V AC/DC control supply covers both European 230 V and North American 120/208/240 V control circuits without needing a separate transformer tap. The wide operating temperature range suits unheated enclosures in temperate climates.","metaTitle":"Siemens 3RT1916-2CH11 SIRIUS Timing Relay, ON-Delay 0.05...1","metaDescription":"Siemens 3RT1916-2CH11 SIRIUS timing relay, ON-delay, adjustable 0.05...1s, 90...240 V AC/DC, clip-on for 45 mm width.
