Description

Siemens TXS1.12F10 Power Supply Module

Product Dimensions：

The Siemens TXS1.12F10 is a high-performance power supply and bus supply module designed for use within the Siemens Desigo building automation system. It primarily serves as a power source for TX-I/O modules and peripheral devices.

## Product Overview

The TXS1.12F10 is a compact, DIN-rail mounted power module. It provides a stabilized DC 24V output to power TX-I/O modules and can also supply the AC 24V required for field devices (valves, actuators, and sensors).

## Technical Specifications

## Key Advantages

• Integrated Design: Combines power supply and bus communication support in a single module, saving space in the control cabinet.

• System Protection: Includes built-in protection against short circuits and overloads, ensuring the longevity of connected I/O modules.

• Status Diagnostics: Features LED indicators (typically green/red) that provide instant visual feedback on the health of the power supply and the bus.

• Modular Scalability: Easily snaps into the TX-I/O bus sequence, allowing for quick expansion of the automation system.

## Product Applications

The TXS1.12F10 is essential in medium to large scale Building Management Systems (BMS), specifically:

1. HVAC Control: Powering I/O modules that manage air handling units (AHUs), boilers, and chillers.

2. Field Device Powering: Providing the necessary AC 24V for peripheral actuators and sensors via the I/O bus.

3. Data Communication: Stabilizing the DC voltage required for reliable communication across the TX-I/O bus.

## Important Precautions (Usage Notes)

• Load Calculation: Ensure the total current consumption of all connected I/O modules and field devices does not exceed 1.2 A for the DC bus. If exceeded, an additional TXS1.12F10 must be added to the line.

• Parallel Connection: Do not connect the DC 24V outputs of multiple power supply modules in parallel. Each power segment must be isolated according to Siemens wiring guidelines.

• Earthing: Ensure the system is properly grounded to prevent electrical noise from interfering with sensitive automation signals.

• Heat Dissipation: Install the module vertically to allow for natural convection cooling; avoid placing it directly above heat-generating components.
