HART to Modbus Converter SM101-B - Reliable Industrial Supplies from China Factory, HART to RS232/RS485 Solutions

The SM101-A(B) is a state-of-the-art HART intelligent converter developed by JIAXING SONGMAO, a leading supplier and factory in China. This innovative device utilizes an ARM microprocessor and HART protocol modulation and demodulation ASIC, reflecting extensive research and practical applications. Engineered to meet the stringent reliability and stability requirements of industrial products, the SM101-A(B) offers high performance.

Equipped with standard RS232 and RS485 interfaces, this intelligent converter enables seamless communication with HART protocol instruments and can convert signals to MODBUS_RTU protocol for real-time data retrieval. The HART protocol adheres to the Bell202 Frequency Shift Keying (FSK) standard, allowing for bidirectional data communication without disrupting the analog 4-20mA signals. The SM100 series intelligent converters excel in facilitating both digital and analog signal modulation and demodulation, making them an ideal choice for industrial applications.
