Product Details

Product Introduction

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.

Frequently Asked Questions

Q1: What is the primary function of the SM100-B-F HART smart converter?

The SM100-B-F is designed for bidirectional modulation and demodulation of digital and analog signals. It enables transparent data transmission between HART protocol smart instruments and RS485 systems, supporting MODBUS_RTU protocol commands.

Q2: What standard protocols does the SM100-B-F converter support?

It supports standard MODBUS_RTU protocols, single HART protocol intelligent instrument connections, and various special HART protocol commands.

Q3: What are the power supply requirements for the converter?

It requires a DC 12V to 24V power input. The ripple of the power supply should not exceed 200mA (or 200mV for main parameters), and it must provide a current of 100mA.

Q4: Can the SM100-B-F operate in harsh industrial environments?

Yes, the converter is housed in an industrial general explosion-proof aluminum shell, making it suitable for explosion-proof areas. It has a working temperature range of -20 ℃ to +80 ℃ and relative humidity tolerance of 10% to 80%.

Q5: How does the RS485 interface improve system operation speed?

The standard RS485 interface allows users to configure parameters, communication baud rates, and parity bits independently of the 1200 bps communication speed on the HART bus, thereby improving overall system operation efficiency.
