Product Description

The TAC Xenta 401:B is a “Base” controller (indicated by the :B designation) that does not include an integrated wall-mounting terminal part, allowing for flexible installation in various cabinet configurations. It is a freely programmable LonMark certified device, meaning it can be tailored to specific building control logic using the TAC Menta programming tool. It functions as a primary controller that coordinates subordinate I/O modules like the Xenta 411 or 421.

Technical Specifications

Product Advantages

• High Versatility: Being freely programmable, the 401:B can handle complex sequences of operation, from central plant control to integrated room automation.

• LonMark Certification: It adheres to open standards, ensuring it can communicate with other LonWorks-certified devices from different manufacturers.

• Large Memory Capacity: The 1 MB Flash and SRAM allow for extensive application programs, sophisticated trend logging, and complex alarm handling.

• Scalability: It acts as a master for up to 10 Xenta I/O modules, allowing the system to grow as the building’s requirements expand.

• Robust Data Protection: The battery-backed SRAM ensures that critical data and real-time clock settings are preserved even during total power failures.

Precautions

• Firmware Compatibility: Ensure that the firmware version of the Xenta 401:B matches the version of the TAC Menta software being used for programming.

• Battery Maintenance: The internal battery should be checked periodically. If the “Service” LED indicates a fault, the battery may need replacement to prevent data loss during power outages.

• LonWorks Network Limits: Always observe the physical limits of the LonWorks TP/FT-10 segment (e.g., maximum nodes and total cable length) and ensure proper termination.

• Static Electricity: Like all electronic controllers, handle the device with care to avoid Electrostatic Discharge (ESD) damage to the internal circuitry.

Product Applications

The TAC Xenta 401:B is typically deployed in the following scenarios:

• Central Plant Control: Managing large chillers, boiler plants, and cooling towers where complex logic and multiple I/O points are required.

• Air Handling Units (AHU): Controlling large-scale ventilation systems, including heat recovery, humidification, and multi-stage heating/cooling.

• System Integration: Acting as a gateway or coordinator between a building’s primary workstations and distributed field devices.

• Trend Logging and Scheduling: Serving as a data collector for energy usage trends and managing complex weekly or holiday schedules for a specific zone.
