The HART protocol uses the Bell202 Frequency Shift Keying (FSK) standard to superimpose a modulated digital signal on a 4 to 20 mA basis, allowing the HART protocol instrument to allow bidirectional data communication without interfering with the 4 to 20 mA analog signal. SM101 series intelligent converter is an intelligent converter which can modulate and demodulate digital signals and analog signals in both directions.
The SM101 series intelligent converter utilizes the Bell202 Frequency Shift Keying (FSK) standard to modulate and demodulate digital signals and analog signals in both directions. This allows bidirectional communication on a 4 to 20 mA basis without causing any interference to the analog signal.
The converter supports standard MODBUS_RTU and MODBUS_TCP protocols, in addition to the standard HART protocol communication.
No. Each HART channel is completely isolated from the others, ensuring that the instrument current output remains unaffected even when multiple HART protocol intelligent instruments are connected simultaneously.
The system features a fast data update cycle of 0.8 seconds per connected set. For instance, if you connect four sets of instruments, the complete data set will update in 3.2 seconds.
The device requires a DC 12 ~ 24 V power supply (ripple ≤ 200 mA, current 100mA). It operates reliably in temperatures ranging from -20 ℃ to + 80 ℃ and relative humidity between 10% and 80%.
The unit features a compact industrial universal module shell and supports both standard rail installation and fixed installation methods for convenient commissioning.
