The ARM microprocessor, a HART protocol modem chip, and a great deal of real-world knowledge were used in the development of the SM100-W series HART smart converter. It offers great stability and dependability and is designed to meet the specifications of industrial items. To enable real-time data transmission, the intelligent converter has a standard RS485 interface and gateway that can either convert to MODBUS_RTU/MODBUS_TCP protocol to read data or transparently send data with intelligent instruments using HART protocol.
The HART protocol instrument enables bidirectional data transmission without interfering with the 4 to 20 mA analog signal by superimposing a modulated digital signal on a 4 to 20 mA basis using the Bell202 Frequency Shift Keying (FSK) standard. Digital and analog signals can be modulated and demodulated in both directions using the SM100 series intelligent converter.
It converts HART protocol signals to MODBUS_RTU/MODBUS_TCP protocols, enabling real-time data transmission between intelligent instruments and control systems via RS485.
No, it uses Bell202 FSK standard to superimpose digital signals on top of the analog signal without interference.
Multiple intelligent HART instruments can be connected simultaneously. The data update time scales with the number of units (e.g., 6.4 seconds for 8 units).
The device requires a DC 12 to 24 V power supply with at least 100 mA current and ripple below 200 mA.
Yes, the converter comes with specialized configuration software to adjust parameters and facilitate communication with HART instruments.
The converter supports both fixed installation and standard industrial rail installation for ease of commissioning.
