MODBUS-HART communicates with the equipment with MODBUS-RTU communication function through RS485 interface, which can convert the data in the equipment into HART equipment variable output and support 4 ~ 20 mA current output. The MODBUS-HART hardware structure is designed in full compliance with industrial standards. Special design is adopted in terms of temperature range, vibration, electromagnetic compatibility and interface diversity, which ensures stable operation in harsh environment and provides high quality assurance for your equipment.
