It switches a single normally-open contact at 110-230 V AC/DC, with a rated thermal current of 5 A. The 6.2 mm width saves DIN-rail space in dense cabinets — useful when you're packing I/O or coupling signals between different voltage zones. ## Deployment context The screw terminals face forward for easy wiring access. Typical use is isolating a PLC digital output from a higher-voltage load circuit — the optocoupler input side takes the 24 VDC logic signal, and the output side switches the 110-230 V load. RoHS compliant since 26-09-24.","metaTitle":"Siemens 3RQ4053-1SG30 SIRIUS 3RQ4 coupling relay, 110-230 V","metaDescription":"Active Siemens 3RQ4053-1SG30 output optocoupler relay, 110-230 V AC/DC, 1 NO contact, screw terminal, 6.2 mm wide, 5 A thermal current.
