The Siemens 3RT1916-2CG11 is a SIRIUS timing relay providing an ON-delay function with an adjustable time range of 0.05 to 1 second. After the ON-delay period elapses, the relay switches its output; the recovery time is 50 ms before the timing circuit can be re-triggered.
The adjustable time range (0.05 to 1 s) covers short delay sequences — for example, staggering motor starts or sequencing pneumatic valves. The 50 ms recovery time means the relay can be re-triggered quickly after the delay expires, which matters in fast-cycling applications.
