Description

Industrial automation instrument is upgrading from traditional 4-20mA analog control signal to industrial fieldbus with digital communication function. HART bus had digital communication function and it’s compatible with 4-20mA analog control signal.

In the instruments industry, the traditional 4 – 20 mA analog transmitters are upgrading to the fieldbus with digital communication. HART fieldbus communication has digital communication capability with compatible analog signal. HART MODEM is a necessary and convenient tool for the analog products upgrading and signal exchanging in the control plant.

We provide two kinds of HART modem. HART-RS232 is the converter for HART signal to RS-232 signal. HART-USB is the converter for HART signal to PC virtual series port.
