Product Dimensions：

The Schneider Electric TAC Xenta 302 is a high-end, freely programmable controller and communication interface designed for the LonWorks building automation network. It is a key component of the EcoStruxure Building Operation system (formerly known as the TAC Vista system). It functions as an Area Controller or a Central Control Unit for various systems within commercial buildings.

Product Specifications

Product Type: Programmable LonWorks Controller/Area Controller
Communication Protocol: LonTalk protocol over a TP/FT-10 (Twisted Pair Free Topology) channel.
Programming Environment: Configured using TAC Menta, a graphical programming tool, allowing for customized control strategies.
I/O Configuration: The Xenta 302 includes a combination of built-in inputs and outputs, which are typically used for local control or connection to field devices.

Inputs (Universal): 8 inputs, configurable as digital or analog (current, voltage, or resistance).
Outputs (Analog): 4 analog outputs, typically 0-10 VDC, used for controlling actuators or dampers.
Outputs (Digital): 4 digital outputs (triacs), used for controlling small loads, relays, or contactors.

Local Operator Panel (Optional): Supports connection to a TAC Xenta OP (Operator Panel) for local user interaction, viewing status, and overriding setpoints.
Power Supply: Typically operates on $24 \text{ VAC}$ or $24 \text{ VDC}$ .
Clock and Calendar: Includes a real-time clock with battery backup for scheduling and time-based control functions.
Memory: Features sufficient memory for complex control applications and logging.
Housing: Designed for DIN rail mounting in a control cabinet.

Product Advantages

Full Programmability: Unlike fixed-function controllers, the Xenta 302 is freely programmable using TAC Menta, allowing system integrators to create sophisticated, customized control strategies for complex applications like air handling units, central plants, or specialized zones.
High-Level Control: It acts as a supervisory controller, managing and coordinating multiple field devices (like TAC Xenta 100 or 200 series controllers) on the LonWorks network.
Open Protocol (LonWorks): Utilizing the LonWorks protocol ensures interoperability with a wide range of third-party devices and systems that adhere to the LonTalk standard.
Robust Design: Designed for continuous operation in building environments, providing reliable performance for critical HVAC and building services control.
Integrated Scheduling: The built-in real-time clock and battery backup ensure accurate time schedules, setpoint changes, and trend logging, even during power fluctuations.

Important Considerations (Precautions)

Proper Enclosure: The device is designed for indoor use and must be installed within a suitable control cabinet (panel) that provides protection from dust, moisture, and extreme temperatures.
Power Isolation: Always ensure the control power ( $24 \text{ VAC/VDC}$ ) is disconnected before making or breaking any connections to prevent equipment damage or electric shock.
Wiring Standards: All wiring must comply with local and national electrical codes. Segregate low-voltage communication wiring from high-voltage power wiring to prevent electrical noise interference.
Software Tools Required: The controller requires specialized software tools, namely TAC Menta for programming and TAC Vista or EcoStruxure Building Operation for network integration and commissioning.
Installation Environment: Avoid installing the controller in areas with excessive vibration, direct sunlight, or high levels of electromagnetic interference.

Product Applications

The TAC Xenta 302 is primarily used as a central control unit in medium to large commercial, institutional, and industrial buildings to manage key building services.

Air Handling Units (AHUs): Used for comprehensive control of complex AHUs, including variable air volume (VAV) control, optimal start/stop, energy recovery sequences, and temperature/humidity control.
Central Plant Control: Managing chillers, boilers, cooling towers, and associated pumps, optimizing their operation for energy efficiency.
General HVAC and Lighting Control: Acting as a supervisory controller for a group of zone controllers (e.g., Xenta 100/200 series) for HVAC, and coordinating with lighting control systems.
Energy Management Systems (EMS): Implementing and enforcing energy-saving strategies, demand limiting, and complex scheduling across the building.
Custom Building Automation: Due to its free programmability, it is suitable for unique and highly specialized control applications that require custom logic and sequencing.
