Product details

The Siemens 3RQ4070-1SG30 is a SIRIUS 3RQ4 coupling relay in the narrow 6.2 mm housing. It uses an optocoupler input rated for 110-230 V AC/DC, providing galvanic isolation between the control circuit and the single normally-open (NO) contact. The contact is rated for a thermal current of 5 A, which is the continuous current it can carry in free air without derating.

At 6.2 mm wide, it occupies minimal rail space — useful when you need to isolate a PLC digital output driving a higher-voltage load without dedicating a full-width interface relay.

Compliance notes

RoHS compliant since 26 September 2024. Export control classification is AL: N / ECCN: EAR99 — no special licensing required for standard commercial shipments.
