China HART data collector, hart gateway, 8-channel hart to modbus protocol converter SM100-M-8 Manufacturers, Suppliers

A product called the SM100-M-8 HART data collector was created using an ARM microprocessor, a HART protocol modem chip, and a great deal of real-world experience. It offers great stability and dependability and is designed to meet the specifications of industrial items. To ensure real-time data transmission, the data collector is outfitted with a standard RS485 interface and gateway that can either convert data into MODBUS _ RTU or MODBUS _ TCP protocol to read data or transparently communicate data with intelligent instruments using HART protocol. The HART protocol instrument enables bidirectional data transmission without interfering with the 4 to 20 mA analog signal by superimposing a modulated digital signal on a 4 to 20 mA basis using the Bell202 Frequency Shift Keying (FSK) standard.
