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.

Hart Communicator Modem: 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.

Hart Communicator Modem Usage Instruction:

HART Modem is the protocol converter between HART device and configurator on PC.

4 20 ma hart

The figure above is a sample basic case. To connect multiple HART device, please connect the other devices parallel with the “Transmitter”. Please note that the power should support multiple devices and the terminator should be set in the middle of the power and parallel point.

 

HART-RS232 is a HART MODEM with voltage modulator/demodulator. To communicate with a HART device, please connect the clincher of HART port of HART-RS232 to the two terminals of the network adaptor resistance or the power of HART device. To communicate with a PC, please connect the other port of HART-RS232 to the series port of PC.

 

The USB driver installation program should be run for HART-USB. The driver provides a virtual series ports for HART configurator software.

 

The indication light shows the state of modem. Green LED indicates the power is working well and the modem is sending data. Red LED indicates the modem is receiving data.
