China hart to modbus converter, hart to 485 converter, Industrial supplies,SM101-B Manufacturers, Supplier

The SM101-A(B) is HART intelligent converters designed by JIAXING SONGMAO. It is researched and developed by ARM microprocessor, HART protocol modulation and demodulation ASIC, and experienced with a lot of practical applications. The design is in accordance with the requirements of industrial products with high reliability and stability. The intelligent converter is equipped with standard RS232 and RS485 interfaces, which can be transparently transmitted to the intelligent instruments with HART protocol or converted to MODBUS_RTU Protocol to read data, ensuring the live transmission.

The HART protocol is complied with the standard of Bell202 Frequency Shift Keying (FSK), and modulate digital signals on a basis of 4~20mA, which leads the HART protocol instruments to bidirectional data communication without interfering the analog signal of 4-20mA. The intelligent converters of SM100 series are for bidirectional modulation and demodulation with digital signals and analog signals.
