Siemens 3RQ4038-2AB00 Input coupler 1 change-over 10 pc(s)

Input coupler with integrated relay, AC/DC 24 V, 1 changer, spring-loaded connection (push-in), width 6.2 mm, Thermal current 6 A Interface relay with integrated SIRIUS 3RQ4 relay output for galvanic isolation, amplification and signal adaptation between control and I/O. Very small and compact, fast and error-free wiring due to the continuous bridging capability of all potentials, several labeling areas available for terminal and device identification, optimized use with Siemens controls (e.g. ET200SP, S7-1200 or S7-1500). Available as coupling relays with relay output, with semiconductor output or plug-in relay, with various operating voltages and output currents as well as hard gold-plated contacts or with manual automatic switching. Uniform accessories for all device variants, such as connecting combs, clip plates or potential separation plates simplify the selection and storage. The 3RQ4 coupling relays replace the tried and tested 3RQ3 series. SIRIUS relay - a program for all cases.
