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 (FAQ)
Q: What is the primary function of the SM100-B-F HART smart converter?
The SM100-B-F is designed to transparently transmit data with intelligent instruments using the HART protocol or read data with the MODBUS _ RTU protocol via a standard RS485 interface to ensure real-time communication.
Q: How does the HART protocol communicate without interfering with 4-20 mA analog signals?
It uses the Bell202 Frequency Shift Keying (FSK) standard to superimpose a modulated digital signal on top of the 4-20 mA analog signal, enabling bidirectional communication without interference.
Q: Is the SM100-B-F suitable for hazardous industrial environments?
Yes, it is built with an industrial general explosion-proof aluminum shell, making it suitable for deployment in explosion-proof areas.
Q: What are the power requirements for operating this converter?
It requires an input voltage of DC 12 ~ 24V, with a power supply ripple not exceeding 200 mV (or 200 mA depending on configuration), and the power source must provide a current of 100mA.
Q: Does it support configuration software for parameter modification?
Yes, it comes equipped with special configuration software to configure parameters, adjust communication baud rates, and set parity bits independently of the 1200 communication speed on the HART bus.
Q: What is the operating temperature range for the SM100-B-F?
The converter is designed to function reliably in working temperatures ranging from -20 ℃ to + 80 ℃.
