Fujitsu Modbus gateways - modules for home, VRF and RAC series air conditioners

Modbus communication modules for Fujitsu air conditioners

This category contains Fujitsu Modbus communication modules, which allow Fujitsu indoor home, VRF and RAC air conditioners to be connected to and managed by master systems such as BMS or SCADA using the Modbus communication protocol. Thanks to the communication modules, air conditioners can be managed remotely, enabling faster fault diagnosis, temperature and power regulation and control of other functions, helping to save time, energy and extend the life of the units.

List of compatible indoor units can be found in the documents - COMPATIBILITY LIST, COMPATIBILITY LIST 2.

Fujitsu Modbus communication module features and functions

Communication modules make it possible to connect from one home series unit to up to 16 VRF and RAC series air conditioners to the gateway simultaneously. The Gateway for the VRF and RAC versions controls all units in groups, making it impossible to control individual air conditioners, so the most common solution in both cases is a 1:1 configuration.

The Fujitsu Modbus modules can be serialised on a Modbus RTU (RS-485) network, allowing them to be combined into one wide area network with up to 63 units. The modules are configured via DIP-switches or Modbus RTU protocol, and the modules can operate with an air-conditioning remote control. All units are internally powered, have 1500VDC isolation and can be wall or DIN rail (TH35) mounted.
