Mitsubishi Heavy Industries to Modbus TCP/RTU - 1 indoor unit

Mitsubishi Heavy Industries FD and VRF systems to Modbus RTU Interface

Item number INMBSMHI001R000

The Mitsubishi Heavy Industries-Modbus interface allows full bidirectional communication between Mitsubishi Heavy Industries FD and VRF systems and Modbus RTU (RS-485) networks. The interface acts as a server device for the installation, accessing all signals from the air conditioner unit. A wired remote controller can also be part of the network.

Features and benefits

  • Modbus RTU (EIA-485) server device

    The interface acts as a Modbus server device through its Modbus RTU (EIA-485 connector) port.

  • Dual configuration options

    Configuration is carried out through the interface's onboard DIP switches and the Modbus interface.

  • Energy savings through a window contact function

    This function helps minimize costs, as HVAC systems are a major building energy consumer.

  • Total unit control and monitoring from Modbus RTU

    Through internal variables, running hours counter (for maintenance purposes), and error indication.

  • AC unit control by both the remote and Modbus RTU

    The AC unit can be simultaneously controlled by the manufacturer's remote controller and Modbus RTU.

  • No external power required

    The interface is powered directly from the AC unit, so no external power supply is required.

  • Multiple mounting options

    Mounting options include DIN rail, wall, or, in some AC models, even inside the indoor unit.
