Product Details
1、 Product Introduction
The SM100-B-F HART intelligent converter is a product developed using an ARM microprocessor, a dedicated chip for modulation and demodulation of the HART protocol, and extensive 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 the HART protocol or use MODBUS_ The RTU protocol reads data to ensure real-time transmission of data.
The HART protocol uses the Bell202 Frequency Shift Keying (FSK) standard, which superimposes modulated digital signals on a 4-20mA basis, allowing the HART protocol instrument to allow bidirectional data communication without interfering with 4-20mA analog signals. The SM100 series intelligent converter is an intelligent converter that performs bidirectional modulation and demodulation between digital signals and analog signals.
2、 Product Features
● Equipped with RS485 communication interface, it can configure parameters, change communication Baud and Parity bit, independent of the 1200 communication speed on the HART bus, so as to improve the operation speed of the whole system.
Adopting industrial universal explosion-proof aluminum casing, suitable for use in explosion-proof areas.
Equipped with dedicated configuration software, through the SM100 series intelligent converter, data communication with the HART protocol intelligent instrument and parameter configuration of the intelligent converter can be achieved
