Siemens 3TX7005-4PG24 SIRUS Output Coupling Link

Siemens 3TX7005-4PG24 is a SIRUS output coupling link that connects a 110–230 V AC control signal to a semiconductor output within SIRIUS safety-relay configurations, enabling signal coupling and output expansion in industrial control panels. As part of the 3TX family, it provides a compact, high-compatibility interface and features a spring-type terminal (cage clamp) for secure wiring, with a narrow enclosure width of 6.2 mm for restrained panel space. The unit is rated for an output current of 0.1 A and a maximum DC output of 30 V, supporting reliable signaling to actuators or signaling elements without overloading the controller. This coupling link is designed to facilitate safe, straightforward interfacing between higher-voltage control logic and semiconductor outputs in automation systems.
