The Siemens 3RQ4118-2AB01 is an output coupler relay from the SIRIUS 3RQ4 family, designed for narrow-panel applications. It's a plug-in relay with a 24 V AC/DC coil and one change-over contact rated for 6 A thermal current. The spring-loaded push-in terminal saves wiring time compared to screw terminals, and the 6.2 mm width means it packs tight on a DIN rail — useful when you're squeezing I/O slices into a crowded enclosure.
