It accepts a 24 V AC/DC coil supply and switches one change-over contact rated for a thermal current of 6 A. The hard gold-plated contacts are the key detail here: they handle low-level signals (milliamps, millivolts) reliably without oxidation issues, which standard silver-alloy contacts can develop when switching dry circuits in PLC or electronic load applications. The plug-in relay base means the coil/contact module can be swapped without disturbing the wiring — a practical detail for commissioning or fault isolation on a populated rail. The 24 V AC/DC coil covers both common control voltages, so it works in AC-sourced panels or DC-supplied PLC cabinets without a separate coil voltage variant.","metaTitle":"Siemens 3RQ4118-1AB01 SIRIUS 3RQ4 Coupling Relay, 6 A, 24 V","metaDescription":"Siemens 3RQ4118-1AB01 SIRIUS 3RQ4 output coupler with plug-in relay, 24 V AC/DC, 1 change-over contact, screw terminal, 6.2 mm wide, 6 A thermal current, hard gold-plated contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Control Accessories"],"specifications":{"title":"3RQ4118-1AB01","Group Code":"R711","description":"output coupler with plug-in relay, 24 V AC/DC, 1 change-over contact, screw terminal, width 6.2 mm, thermal current 6 A, hard gold-plated","Product Group":"4950","Product class":"A: Standard product which is a stock item could be returned within the returns guidelines/period.","Quantity Unit":"1 Piece","Product Family":"SIRIUS 3RQ4 coupling relays, narrow design","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : EAR99","Packaging dimensions (L x W x H)":"95.00 x 93.00 x 65.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 26-09-24","REACH Art. 33 Duty to inform according to the current list of candidates":"Reach Information"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/386cd4bc4cd8351d436887ab57874200.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/3RQ4118-1AB01?tree=CatalogTree"},"ai":{"faq":[{"question":"What compliance documentation is available for this relay?","answer":"RoHS compliance is confirmed since 26 September 2024, and REACH candidate list information is provided.
