Product details

The Siemens 3RQ4053-1SG30 is an output optocoupler relay from the SIRIUS 3RQ4 family, designed for narrow control-panel mounting. 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.
