Output coupler optocoupler 1 S, transistor, DC 24 V output max. DC 30 V, short-circuit proof 2 A, spring connection (Push-In), width 6.2 mm, thermal current 2A. Coupling relay with semiconductor output (non-pluggable) SIRIUS 3RQ3 for galvanic isolation, amplification, and signal adaptation between control and peripheral devices. Very narrow and compact. Fast and error-free wiring due to the continuous bridging of all potentials. Multiple labeling surfaces for terminal and device identification are available. Available as a 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 separation plates, simplify selection and inventory management. SIRIUS relays - a program for all cases.
