OverviewChapter 1

Product Name: HART to Modbus Gateway

Model No: G1003

The gateway realizes protocol converting from HART to Modbus RTU / ASCII. Supporting to

connect multi HART slave devices into Modbus network. In the gateway, HART terminal is

master station, Modbus terminal is slave station.

2.2.6Internal /External Sampling Resistor Selection Switch (RS)

The HART to Modbus Gateway allows the user to select internal or external sampling

resistor to obtain HART signals. The internal resistor is 250Ω, 1W. The user must use

external resistor if the power of sampling resistor is more than 1W.
