Schneider TAC Xenta 400 0-073-0902-0 Control Terminal

Product Description

The Schneider (formerly TAC) Xenta 400 Terminal Part (0-073-0902-0) is a dedicated terminal base used to provide the physical connections for power, communications, and I/O wiring to a compatible TAC Xenta 400 series electronic unit (such as the Xenta 401, 411, 412, etc.).

It is designed for DIN rail mounting and features screw terminals for secure wiring. This two-part design (base terminal + plug-in electronics) allows for hot-swapping of the electronic unit without having to disconnect and re-wire the entire system, significantly simplifying maintenance and reducing downtime.

Key Technical Specifications (for the Terminal Part)

Note: The specific I/O counts (like Universal Inputs, Analog Outputs, Digital Outputs) are defined by the electronic module that plugs into this terminal base, not the base itself.

✨ Product Advantages

The use of a separate terminal part offers several operational and maintenance benefits:

• Simplified Maintenance: The electronic control unit can be quickly replaced (hot-swapped) without disconnecting any field wiring, dramatically speeding up service and troubleshooting.

• Reduced Downtime: Quick module replacement means the building system can be brought back online faster, minimizing disruption to operations.

• Cost-Effective Installation: Wiring can be completed on the terminal base first, even before the electronic module arrives or is installed, simplifying the overall installation process.

• Reliable Connections: High-quality screw terminals ensure secure and durable electrical connections for critical building automation signals.

• DIN Rail Mounting: Standardized mounting allows for easy and organized integration within control panels.

⚠️ Precautions and Safety Notes

When installing and working with the TAC Xenta 400 Terminal Part, the following should be observed:

• Authorized Personnel Only: Installation and wiring should only be performed by qualified, licensed technical personnel familiar with low-voltage control systems and local electrical codes.

• Power Disconnection: Always disconnect power to the controller and system before performing any wiring changes or before plugging/unplugging the electronic module, unless the electronic unit is explicitly designed for hot-swap. Even then, best practice is to power down for major work.

• Correct Wiring: Ensure all field wiring (power, communication, I/O) is connected to the correct terminals as specified in the TAC Xenta 400 series module’s documentation. Incorrect wiring can damage the electronic unit.

• Environmental Limits: Ensure the control panel environment (temperature, humidity, and protection class) remains within the limits specified for the overall Xenta 400 system.

• Cable Routing: Separate high-voltage wiring from low-voltage I/O and communication cables to prevent electrical noise interference.

🎯 Product Applications

The TAC Xenta 400 series, using this terminal base, is a core component of building automation and control systems (BMS/BAS).

• HVAC Control: Primary application, including control of:

  • Air Handling Units (AHUs)

  • Chillers and Boilers

  • Fan Coil Units (FCUs) and VAV (Variable Air Volume) Systems

  • Plant Room Equipment

• Building Integration: Used as an integration unit in open control and supervisory systems, leveraging the LonWorks communication standard to connect various building systems.

• General Automation: Any application requiring programmable, networked control logic and reliable I/O connections within a commercial building environment.

• System Upgrades/Replacements: Used as a reliable component for expanding, upgrading, or replacing existing TAC Xenta 400 installations.
