SM100-B-H 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 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 4-20 mA basis, allowing the HART protocol instrument to communicate data in both directions without interfering with the 4-20 mA analog signal. SM100-B-H intelligent converter is an intelligent converter that modulates and demodulates digital signals and analog signals.
