MODBUS-HART Converter

NCS-MH105 communication board 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 communication board. RS485 electrical interface requires an external 5V power supply. BriefIntriducion Compliant with HART 6.0 standard, provide HART communication ability to MODBUS device Support all HART universal commands and common practice HART commands Support device specific commands on demand Support HART multidrop mode Support HART communication burst mode Support handheld 375/475 Electrical interface connected withMODBUS device supports TTL level, RS485 and RS232 NCS-MP105 Application Gas detector Analyzer Positioner Any smart device with MODBUS protocol Physical Parameters Bus signal:4 20mA output with HART protocol,digital communication Bus power supply: 11.9 42V Operating temperature: -40 85°C Static current: ≤14mA Humidity range: 5% 95%,non-dew Mechanism size:96mm*66mm(can be customized) Supportive MODBUS Communication Parameters Address: 1 255 Baud rate:2400 / 4800 /9600 / 19200/35700 / 38400/ 57600bps 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
