China hart to 485, 4-20mA to 485, hart smart converter , SM181-01-A Manufacturer, Factories

SM181-01-A HART smart converter is A product developed by using ARM microprocessor, HART protocol modem chip and combining with A lot of practical experience. It is designed according to the requirements of industrial products and has high reliability and stability. The intelligent converter is equipped with a standard RS485 interface, which can transparently transmit data with intelligent instruments with HART protocol or convert to MODBUS _ RTU protocol to read data, so as to ensure real-time data transmission.
The HART protocol uses the Bell202 Frequency Shift Keying (FSK) standard to superimpose a modulated digital signal on a 4 to 20 mA basis, allowing the HART protocol instrument to allow bidirectional data communication without interfering with the 4 to 20 mA analog signal. SM181-01-A HART intelligent converter is an intelligent converter that modulates and demodulates digital signals and analog signals in both directions.
