Output coupler Relay coupler, 1 changeover contact AC/DC 230 V Width 6.2 mm Screw connection Thermal current 6A Coupling relay with relay output (not pluggable) SIRIUS 3RQ3 for galvanic isolation, amplification and signal adaptation between control and peripherals. Very slim and compact. Fast and error-free wiring due to the continuous bridging of all potentials. Several labeling areas available for terminal and device labeling. Available as coupling relay with relay output, with semiconductor output or with plug-in relay, with various operating voltages and output currents as well as with hard gold-plated contacts or with manual-automatic switching. Uniform accessories for all device variants, such as connection combs, clip labels or potential isolation plates simplify selection and storage. SIRIUS relays - a program for all cases.
