Product Description

The TAC Xenta 452A serves as an interface between the control system and the physical equipment in a building. It is distinguished from the 451A model by its integrated hardware for local interaction, including status LEDs for inputs and manual override switches for outputs. These features allow maintenance personnel to monitor and control equipment directly at the electrical panel.

Technical Specifications

Product Advantages

• Flexible Input Configuration: The universal inputs can be software-configured to handle various signal types, reducing the need for multiple specialized modules.

• Local Manual Control: The manual override switches and potentiometers allow for emergency operation or testing of analog outputs without software intervention.

• Visual Diagnostics: Built-in LEDs provide immediate visual feedback on the status of digital inputs, simplifying troubleshooting during site visits.

• Open System Architecture: Being LonMark certified, it integrates seamlessly into open standard LonWorks networks, ensuring interoperability with third-party devices.

• Ease of Installation: Designed for DIN-rail mounting with a modular “terminal part” and “electronics part” design, allowing for easy replacement without disturbing the wiring.

Precautions

• Polarity and Wiring: Ensure correct power supply polarity; while the device has protection, incorrect wiring can lead to unstable communication or damage.

• Configuration Tools: Initial setup requires the TAC Menta graphical tool or the Device Configuration Tool. Ensure you have the correct software version for the system firmware.

• Network Limits: When used as a LonWorks device, follow standard Echelon wiring rules regarding cable lengths and termination resistors to prevent data loss.

• Manual Override Awareness: Always check the position of the manual switches (Auto/Manual) after maintenance, as leaving them in Manual may prevent the central controller from managing the equipment.

Product Applications

The TAC Xenta 452A is primarily used in Building Automation Systems (BAS) for:

• HVAC Control: Monitoring temperature sensors (thermistor) and controlling valves or dampers (analog output).

• Lighting Management: Receiving signals from occupancy sensors and controlling dimmable lighting ballasts.

• Pump/Fan Monitoring: Tracking status through digital inputs and adjusting motor speeds via Variable Frequency Drives (VFDs) using the 0–10V outputs.

• Distributed I/O: Expanding the capacity of a central TAC Xenta 300 or 400 series controller across a large facility.
