📦 Product Introduction

The SM100-B-F HART smart converter is a high-performance industrial product developed using an ARM microprocessor and specialized HART protocol modem chips. Designed to meet rigorous industrial standards, it offers exceptional reliability and stability. This converter features a standard RS485 interface, enabling transparent data transmission with HART protocol instruments or data retrieval using the MODBUS_RTU protocol to ensure seamless real-time communication.

Utilizing the Bell202 Frequency Shift Keying (FSK) standard, the HART protocol superimposes digital signals onto the traditional 4-20 mA analog signal. This allows for bidirectional communication without interfering with the analog measurement. The SM100-B-F serves as the critical bridge for the bidirectional modulation and demodulation of these complex signals.
