Coupling relay in an industrial housing 3 changeover contacts hard gold plated wide voltage AC/DC 24 V to 240 V spring-loaded connection Coupling relay in an industrial housing SIRIUS 3RQ2 for coupling control signals to and from a controller. , All 3RQ2 coupling relays have a wide-range voltage input and are therefore universally applicable. The reduction in variants leads to cost savings. High contact reliability is present even at low currents. Removable terminals enable easy device replacement and quick wiring. , Devices with one to three changeover contacts are available, with screw or spring-loaded connection (push-in), some also with hard gold plated contacts for switching small currents. , The 3RQ2 coupling relays replace the tried and tested 3RS18 series. , SIRIUS Relay - a program for all cases.
