Sirius 3RQ2 has a minimal mounting depth of 3.5” and wide-range power supply from 24 to 240V AC/DC. The relays are available in variants with one and three changeover contacts. Designed to replace the company’s 3RS18 Series, the coupling relays use the same terminal assignment and minimize the variant options to simplify changeover. Typical applications include galvanic isolation, signal amplification and voltage conversion, and overvoltage and EMC protection for control systems. The variants with hard gold-plated contacts for switching currents in the lower milliampere ranges are particularly suited for PLC inputs and outputs.
