USB Hart Modem/ USB Hart Converter
The USB Hart modem (also called as USB Hart converter) is for the application where HART communication is needed.HART is a very popular communication protocol in industry control.In order to set related parameters for HART device, a Hart communicator is needed, but some has a higher cost. As computer technology develops, PC,especially laptop has no RS232 port and USB is good choice. So we develop the HART-USB converter.It is an ideal choice to replace HART operator.
USB2.0 port is standard configuration of PC and laptop,so the USB Hart modem or USB Hart converter can be widely used for HART net work by PC.
The Hart modem is developed based on the international standard of Bell202 and can be completely used for HART protocol communication to USB port of PC and laptop.By the HART-USB converter,HART receiving and sending commands can be sent to USB port without external power supply.
It is easy to connect wire as HART terminals have no difference of positive and negative and no need to make any setting for them. And the USB port is standard USB-A.
With simple and solid industry class enclosure design,and good compatability with HART Configuration Software.Without external power request,the USB Hart modem or USB Hart converter can isolate the AC current between device and connection terminals and ensure a very minor current leakage.
