Product Details

Product Specifications

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.

Product Features

Equipped with standard RS485 communication interface and gateway, it can configure parameters, change communication baud rate and parity check bit. It is independent of the 1200 communication speed on the HART bus, thus improving the operation speed of the whole system.

Adopt industrial universal module shell, which is convenient for installation and commissioning.

It is equipped with special configuration software, which can configure the parameters of SM101-W series intelligent converter, and can communicate with HART protocol intelligent instrument through the intelligent converter.
