Product Details
1.1 Product Introduction
The SM101 series of HART intelligent converters are products developed using ARM microprocessors, specialized chips for modulation and demodulation of the HART protocol, and extensive practical experience. It is designed according to the requirements of industrial products and has high reliability and stability. The intelligent converter is equipped with standard RS232 and RS485 interfaces, which can transparently transmit data to intelligent instruments with the HART protocol or convert to 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 SM101 series intelligent converter is an intelligent converter that performs bidirectional modulation and demodulation between digital signals and analog signals.
1.2 Product Features
● Equipped with standard RS232 and RS485 communication interfaces, it can configure parameters, change communication Baud and Parity bit. It is independent of the 1200 communication speed on the HART bus, thereby improving the overall operating speed of the system.
Adopting an industrial universal module casing for easy installation and debugging.
Equipped with dedicated configuration software, the SM101 series intelligent converter can be configured with parameters, and through the intelligent converter, data communication can be carried out with the HART protocol intelligent instrument.
● Support standard MODBUS_ RTU protocol.
Supporting various special HART protocol intelligent instruments and being able to customize and read commands from special HART instruments.
