NCS-MH105 Is a converter device for MODBUS-RTU protocol to HART protocol. as a MODBUS Host, NCS-MH105 communicates with the device with MODBUS-RTU communication Ability, it converts the data in the device to HART device variables, and Supports 4~20mA current output.

NCS-MH105 Converter supports 4 dynamic variables, 6 device variables, all HART universal Commands, common practice HART commands and standard MODBUS-RTU protocol. the Mechanism size is 96 mm * 56 mm, which not only matches standard Adam module Housing, also can be installed to device through positioning hole.

HART Bus gives power supply to NCS-MH105 converter. RS485 electrical interface Requires an external 5V power supply.
