Siemens 3TX7 002-3AB01 DIN Rail Coupling Relay Output Interface

Siem ens 3TX7002-3AB01 DIN Rail Coupling Relay Output Interface is a compact, 24 V DC coil input module that translates a control signal into a single normally-open (SPST‑NO) optocoupler relay output, providing electrical isolation between the control and load circuits. This 3TX7 family device is 11.5 mm wide and designed for snap‑on mounting on a standard 35 mm DIN rail, finished with IP20 protection and protective separation between the coil and the contacts up to 300 VAC. The coil runs on 24 V DC and draws under 0.5 W of power at 24 V, with screw terminals for both the coil and the output connections, making it a straightforward interface to PLCs or other control logic while isolating the control electronics from the load. As part of Siemens LV 1 and 3TX7 coupling-relay offerings, the 3TX7002-3AB01 is intended for modular DIN rail installations where a compact, reliable 24 V control interface is needed to drive external loads via a single, isolated relay output.
