RoHS compliance effective 26 September 2024, and REACH candidate-list information is available on request. No UL or CSA listing is stated in the record, so verify with the factory if your panel requires a third-party mark. ## Integration note Snap-on DIN-rail mount, 24 V DC coil — pull the supply from a standard PELV power supply. The single change-over contact is rated for signal-level loads; the hard gold-plating means it should not be used at the full rated current of a standard power relay without checking the manufacturer's derating curve. Use for isolating 24 V DC digital signals between a PLC output and a field device.","metaTitle":"Siemens 3RQ4914-7BM02 SIRIUS 3RQ4 coupling relay, 1 CO conta","metaDescription":"Siemens SIRIUS 3RQ4 coupling relay, narrow design, 1 change-over contact, 24 V DC coil, hard gold-plated contacts.
