Danfoss 130B1144 Option Card

As a seasoned technician, you know that seamless integration is the backbone of any reliable building management system. The Danfoss 130B1144 is a professional-grade VLT BACnet MS/TP MCA 109 option card designed specifically for high-performance HVAC drive integration. Built for the Danfoss VLT FC 102 and VLT FC 100 series, this non-coated BACnet communication module enables your variable frequency drive to function as a native node on the network, effectively acting as remote I/O for your automation architecture.

By installing the MCA 109 option card, you gain high-speed RS-485 BACnet MS/TP connectivity, allowing for the direct reading and writing of analog and digital points without overloading the BMS controller. This hardware-based solution supports advanced features like Change of Value (COV) reporting and Read/Write Property Multiple, which drastically reduces network traffic and latency compared to standard built-in protocols. Precision-engineered for efficiency, it synchronizes the drive's internal clock with the master system, eliminating the need for battery-backed real-time clocks in the field.

Key Benefits:

• Reduced Integration Costs: Eliminates the need for external gateways by providing native BACnet MS/TP support directly in the drive's A-slot.
• Enhanced System Visibility: Delivers detailed alarm and warning descriptions in plain text to the Building Management System (BMS) for faster diagnostics.
• Optimized Network Performance: Supports COV and multiple property requests to maintain high data throughput even in large-scale HVACR automation projects.
• Versatile I/O Control: Allows independent control of all drive I/O points, maximizing the utility of the VLT HVAC Drive within your control logic.

Common Questions:

Does this card support BACnet/IP?
No, the 130B1144 is specifically designed for BACnet MS/TP (RS-485). If your infrastructure requires Ethernet-based communication, a different MCA option card would be necessary.

Is this compatible with the FC 102 line?
Yes, this Danfoss 130B1144 module is the primary A-Option card for the VLT HVAC Drive FC 102, ensuring full parameter access and protocol compliance.

Can I install this in a running drive?
Installation must be performed with the main power disconnected. After mounting the card in Slot A, the drive will automatically recognize the MCA 109 during the next power-up sequence for configuration.
