BACnet MS/TP Field Controller

A BACnet MS/TP Field Controller is a programmable building automation controller that communicates over the BACnet MS/TP (RS-485) network to monitor and control HVAC equipment, lighting, and other field devices.



A BACnet MS/TP Field Controller is a distributed automation controller used in Building Management Systems (BMS) to manage equipment such as air handling units (AHUs), fan coil units (FCUs), chillers, pumps, boilers, and lighting systems. It communicates using the BACnet MS/TP protocol over an RS-485 network, enabling interoperability between devices from different manufacturers.

The controller processes input signals from sensors and executes control logic to operate actuators, valves, dampers, relays, and variable frequency drives (VFDs), ensuring efficient building operation.
