It operates on a universal supply of 24 to 240 V AC/DC, so it drops into panels with mixed control voltages without needing a separate power supply module. The relay switches a resistive load up to 1 A at 24 VDC, 0.2 A at 125 VDC, or 0.1 A at 250 VDC — enough to drive a small contactor coil or a PLC input directly. Pollution degree 3 rating confirms it can handle conductive pollution typical in industrial control cabinets (dust, condensation, non-corrosive fumes) without creeping failures. The relay is monostable (energize to trip) and offers an external reset input plus error memory — so you can choose to latch the alarm until manually cleared or auto-reset on temperature recovery. Initial value of 0.85 and full-scale value of 1.1 define the threshold trip points as a fraction of the sensor span — typical for PT100 or thermistor inputs. For a sourcing buyer: this is a clean BOM line item. The spread is the business — we quote firm against an RFQ, and the supplier ships clean every time. No surplus hunting needed. ## Integration Notes Dimensions: 100 mm high, 22.5 mm wide, 90 mm deep — a standard single-module width on DIN rail, leaving room for adjacent terminals or breakers. Wire termination accepts solid or stranded conductors from 20 to 12 AWG (1x or 2x 20-14 AWG solid), which covers typical panel wiring. Clearance distances: 0 mm upwards, forwards, backwards, downwards, and at the side — meaning it can be butted directly against other devices without derating, a real space-saver in dense cabinets. Galvanic isolation between input and output, and between outputs, is provided — so a sensor fault won't take down the control signal.","metaTitle":"Siemens 3RS2600-1BW30 SIRIUS Temperature Monitoring
