Product Overview

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.

Features

• Easy to use

• Compatible with all standard HART Instruments

• LEDs for signaling the sending / receiving

• No external power supply required

• Standard USB/RS232 connection to PC

• Galvanic isolation

• Isolated transformer prevents the influence of earthing.

• Voltage signal modulator/demodulator 




Install

HART-RS232 is the protocol converter between HART device and configurator on PC.
