Siemens TXS1.12F4 Temperature Switch Sensor Module

Siemens TXS1.12F4 TX‑I/O Power Supply is a DIN‑rail mounted 24 V DC power module for the TX‑I/O system, delivering up to 1.2 A of continuous output and featuring an integrated 4 A fuse to protect the TX bus and connected TX‑I/O modules. It is designed to energize TX‑I/O bus interface modules and other devices within Siemens automation panels, providing a dedicated 24 VDC supply for TX‑I/O configurations in industrial automation environments. Siemens documentation identifies TXS1.12F4 explicitly as the TX‑I/O Power Supply component that supports P1–P4 TX‑I/O bus modules, underscoring its role as the primary power source in TX installations with a compact DIN rail footprint. The module’s DIN rail mountability and 24 V DC rating enable straightforward integration into space‑constrained control cabinets, helping to ensure reliable operation of the TX ecosystem. Built to meet typical safety expectations for 24 V control circuits, the TXS1.12F4 offers a practical, standards‑based solution for powering Siemens TX‑I/O hardware in automation projects.
