Schneider TAC Xenta 701 Relay Output Module

Description

Schneider TAC Xenta 701 Relay Output Module

The TAC Xenta 701 is part of the TAC Xenta line, which are advanced control and management units primarily used in Building Management Systems (BMS) or Building Automation Systems (BAS). The Xenta 701 specifically is a LONWORKS-based unit designed for controlling and monitoring various plant equipment in large buildings, such as HVAC systems (Heating, Ventilation, and Air Conditioning), lighting, and energy metering. It functions as a flexible controller and a powerful gateway/network interface.

⚙️ Product Specifications (Product Parameters)

The exact specifications can vary slightly depending on the specific model variant, but here are the general parameters for the TAC Xenta 701:

🚀 Product Advantages (Product Advantages)

The TAC Xenta 701 offers several key benefits in a building automation environment:

• Robust Network Backbone: It acts as a powerful central node or server within a LONWORKS network, facilitating communication between multiple distributed controllers (like the Xenta 400 series).

• Scalability and Flexibility: Being part of the Xenta family, it supports flexible, distributed control architecture, allowing the system to easily grow and adapt to building expansion.

• Open Protocol (LONWORKS): LONWORKS is an open standard, which enables integration with a wide variety of third-party devices and systems, promoting interoperability.

• Advanced Control Capabilities: It can handle complex control logic, scheduling, alarming, and trend logging for critical plant equipment.

• Remote Management: When integrated with the TAC Vista software, it allows for remote monitoring, diagnostics, and system configuration, significantly reducing maintenance time.

• Energy Efficiency: By optimizing the operation of HVAC and lighting systems, the controller directly contributes to significant energy savings and operational efficiency.

⚠️ Important Considerations (Attention Points)

• Programming Environment: Programming and configuration require specialized software, usually TAC Menta (for control logic) and TAC Vista (for the management layer).

• Legacy System: While a powerful and reliable product, the Xenta line is an older generation of Schneider Electric’s BMS offerings. Check for long-term support and consider modern alternatives like EcoStruxure if designing a brand-new system.

• Integration Complexity: Integrating the Xenta 701 requires a solid understanding of LONWORKS networking and building control strategies.

• Power Requirements: Ensure the correct power supply (typically 24 VAC) is provided and stabilized, as power fluctuations can affect controller performance.

🏢 Product Applications (Product Application)

The TAC Xenta 701 is typically deployed in large commercial, institutional, or industrial buildings for centralized control and management.

• Central Plant Control: Managing complex central plant equipment like chillers, boilers, cooling towers, and primary pumping systems.

• Building Network Server: Acting as a router or bridge between different segments of the LONWORKS network and the main Building Management System (BMS) workstation.

• Energy Management: Monitoring and logging energy consumption data from meters and optimizing energy-intensive systems.

• Data Aggregation: Collecting data from numerous distributed controllers (e.g., in VAV boxes or zone controllers) and presenting it to the operator interface (TAC Vista).

• Large Scale HVAC Control: Implementing synchronized control strategies for large-scale air handling units (AHUs) and VAV systems across multiple floors or zones.
