MODBUS RS485 TTL to HART Converter

MODBUS RS485 TTL  to HART Converter     NCS-MH105 is a converter device for MODBUS-RTU protocol to HART protocol. It is able to integrate device/board with MODBUS communication interface to PROFIBUS PA bus system. Bus power supply is selected by NCS-MH105, and NCS-MH105 can provide power supply to the boards the user provides.     NCS-MH105 Application Gas detector Analyzer Positioner Any smart device with MODBUS protocol   Physical Parameters Bus signal: compliant with IEC61158-2 physical layer standard Bus power supply: 9 ~ 32V Operating temperature: -40 ~ 85°C Static current: ≤14mA Humidity range: 5% ~ 95%,non-dew Mechanism size: diameter 66mm(can be customized)   Supportive MODBUS Communication Parameters Address: 1 ~ 255 Baud rate: 9600 / 19200 / 15625 / 31250 /62500 / 125000 bps Data bit: 7 / 8 bits Calibration: odd / even calibration Stop bit: 1 / 2 bits CRC calibration: low byte ahead / high byte ahead Data format: support various data formats   Supportive MODBUS Function Code Function Code 1: read loop status Function Code 2: read discrete input status Function Code 3: read keeping register value Function Code 4: read input register value Function Code 6: write loop Function Code 16:write multiple register values
