Product Description

The TXS1.12F10 is a specialized power supply that converts an AC or DC input into a regulated output for the TX-I/O Island Bus. Unlike standard power supplies, this module is specifically engineered to feed the “Bus Power” and “Supply Power” rails that run through the TX-I/O terminal bases. It features built-in fuse protection and status LEDs, making it a critical component for any modular Desigo installation.

Product Parameters

Key Product Advantages

• High Output Capacity: The “F10” designation indicates a 10 Amp supply, allowing it to power a large number of I/O modules and active field sensors (like actuators or valves) from a single point.

• Dual-Level Protection: It provides separate protection for the sensitive electronic bus and the high-current field supply, ensuring a field-side short circuit doesn’t necessarily crash the whole network.

• Seamless Integration: It snaps directly onto the TX-I/O terminal base, automatically distributing power to all adjacent modules via the integrated rail connectors.

• Easy Maintenance: Features an accessible, replaceable fuse on the front panel, allowing for quick recovery without replacing the entire module.

• Compact Footprint: Consolidates power distribution and bus feeding into one unit, saving space in the control cabinet.

Important Considerations (Precautions)

• Fuse Replacement: Always replace the fuse with the exact same rating (10A fast-acting) to prevent fire hazards or damage to downstream I/O modules.

• Total Load Calculation: Before installation, calculate the total current consumption of all connected I/O modules and field devices to ensure it does not exceed the 10A limit.

• Correct Phase: If using AC 24V, ensure proper phasing across multiple power supplies in a large system to avoid potential difference issues between bus segments.

• Heat Dissipation: Ensure adequate ventilation in the cabinet, as the module can generate heat when running near its 10A maximum capacity.

Applications

• Centralized Powering: Serving as the primary power source for a Desigo PXC controller and its associated I/O modules.

• Complex HVAC Plants: Powering large groups of TXM1.6R or TXM1.8RB relay modules where multiple actuators require 24V power.

• Sub-Panel Distribution: Used in remote I/O enclosures where a dedicated local power source is needed for a specific segment of the building automation network.

• System Expansion: Acting as a “Bus Refresher” to provide additional current when an I/O island grows too long for a single supply.
