Product Description

📋 Product Introduction

The ARM microprocessor, a HART protocol modem chip, and a great deal of real-world knowledge were used in the development of the SM100-W series HART smart converter. It offers great stability and dependability and is designed to meet the specifications of industrial items. To enable real-time data transmission, the intelligent converter has a standard RS485 interface and gateway that can either convert to MODBUS_RTU/MODBUS_TCP protocol to read data or transparently send 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. Digital and analog signals can be modulated and demodulated in both directions using the SM100 series intelligent converter.
