The Siemens SIRIUS 3RQ4052-2SM40 is an output optocoupler in the narrow 3RQ4 coupling relay family, designed for 24 V DC control circuits. At 6.2 mm wide, it fits tight enclosure layouts where every millimeter of DIN-rail space counts. The 3 A continuous rating covers typical PLC output isolation and signal-level switching; for motor or heavy inductive loads you'd step up to a contactor or a higher-rated relay in the same SIRIUS family.
RoHS compliant since 26 September 2024.
RoHS declaration of conformity effective 26 September 2024, and a REACH Article 33 notification for lead content above 0.1% w/w. Export controls are AL: N / ECCN: EAR99.
