SM100-B-F HART smart converter is a product developed by using ARM microprocessor, HART protocol modem chip and a lot of practical experience. Designed according to the requirements of industrial products, it 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 read data with MODBUS _ RTU protocol 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 4-20 mA basis, allowing the HART protocol instrument to communicate data in both directions without interfering with the 4-20 mA analog signal. SM100-B-F intelligent converter is an intelligent converter for bidirectional modulation and demodulation of digital signals and analog signals.
