TAC Xenta 701 SCHNEIDER

TAC Xenta 701 SCHNEIDER Power module

Product  Description：

The Schneider Electric TAC Xenta 701 is a powerful, fully programmable, and freely available controller designed for HVAC (Heating, Ventilation, and Air Conditioning) and building automation applications. It is part of the TAC Xenta family, which forms the core control layer in large building management systems (BMS). It is often used as a network controller and a communication gateway within a larger system.

Product Specifications

• Product Type: Fully programmable building automation controller

• Product Series: TAC Xenta 700 series

• Communication Protocol: LonWorks (LonTalk) for network communication and peer-to-peer functionality.

• Programming: Programmed using the TAC Menta graphical programming tool, offering flexible control strategies.

• Connectivity: Features connections for T-Bus communication, which allows for connection to other TAC Xenta I/O modules (e.g., Xenta 400 or Xenta 280/300/401 series), expanding the control points.

• Power Supply: Typically operates on $24 \text{ VAC}$ or $24 \text{ VDC}$.

• Memory: Includes internal memory for storing the control application program and configuration data.

• Real-Time Clock (RTC): Built-in battery-backed RTC for time schedules and calendars.

• Display/Interface: Often equipped with a local service port (LSP) for temporary connection of configuration tools, or integrated with an optional local display for status viewing.

• Mounting: Designed for DIN rail mounting within a control panel.

Product Advantages

• High Flexibility and Customization: Being a fully programmable controller, it allows engineers to implement complex and optimized control sequences using the graphical Menta tool, catering to the unique needs of a building or system.

• LonWorks Networking: Utilizes the robust and interoperable LonWorks protocol, enabling effective peer-to-peer communication and data sharing between controllers, sensors, and actuators from different manufacturers.

• Scalability: The T-Bus connection allows easy expansion of the controller's I/O capacity by adding up to several I/O modules, making it suitable for both small and large applications.

• Distributed Control: Facilitates a distributed control architecture, where control logic is spread across multiple devices, improving system reliability and reducing the impact of a single point of failure.

• Energy Efficiency: The sophisticated control algorithms that can be implemented help optimize HVAC operation, leading to significant reductions in energy consumption.

Important Considerations (Precautions)

• Programming Expertise: Effective utilization requires personnel trained in the TAC Menta graphical programming environment and a solid understanding of HVAC control theory.

• Software Compatibility: Requires specific versions of TAC/Schneider Electric software (like TAC Vista or EcoStruxure Building Operation) for full system integration, commissioning, and continuous management.

• Obsolescence/Migration: Like many older controllers, users should be aware of the product lifecycle. Schneider Electric may recommend migration to newer platforms like the EcoStruxure Building Expert or EcoStruxure Building Operation (EBO) solutions for long-term support and advanced features.

• Power Supply Protection: Ensure the controller is supplied with clean, stable $24 \text{ VAC}$ or $24 \text{ VDC}$ power, protected from surges and brownouts, as unstable power can affect performance and longevity.

Product Applications

The TAC Xenta 701 serves as a highly capable controller for a variety of critical systems within a Building Management System (BMS).

• Central Plant Control: Managing complex central equipment such as chillers, boilers, cooling towers, and primary pump systems, where custom control strategies are essential for efficiency.

• Large Air Handling Unit (AHU) Control: Implementing advanced control logic for large AHUs, including variable air volume (VAV) systems, economizer control, and complex sequences for humidity and temperature regulation.

• Custom Control Loops: Utilized in applications requiring unique or proprietary control logic that cannot be handled by standard application-specific controllers, such as laboratory ventilation or specialized manufacturing environment control.

• Integration Gateway: Acting as a high-level network controller that connects the LonWorks automation level to the building's management level software, enabling system-wide supervision and control.
