The Siemens 3RT1926-2CG11 is an electronic two-wire timing relay with semiconductor output that plugs into Siemens Sirius 3RT contactors. It operates on 24 to 66 V AC or DC supply and provides an on-delay timing range from 0.05 s to 1 s. The timing relay block mounts on contactors sized S0 through S3 and connects to coil terminals A1/A2 on the contactor, using two pins to establish electrical coupling. It is used in automation sequences to introduce a defined delay before energizing a load, leveraging its solid-state output for fast switching.
