Siemens – 3RT1916‑2FJ31 – SIRIUS S00 Off‑Delay Auxiliary Switch (24 VAC/DC)

The Siemens 3RT1916‑2FJ31 is a plug-on, solid-state off‑delay timing module designed for SIRIUS S00 contactors (e.g., 3RT10–3RT16). Powered by 24 V AC/DC, it provides both a normally open (NO) and normally closed (NC) contact with adjustable delay from 5 to 100 seconds, ideal for delayed ejection or shutdown sequences in motor and control circuit applications.
