Using MC5-IS as a Hart Communicator

Connecting MC5-IS and a HART Instrument
MC5-IS also supports HART
rent parallel to a test diode in a 20 mA circuit. The external connec-
tions vary depending on the diode connection of the transmitter:

If you want to use
MC5-IS as a Hart
communicator with-
out measuring/con-
trolling the instru-
ment's output cur-
rent, connect MC5 as
shown in the adja-
cent picture. Again,
make sure that there
is a resistor (or
enough resistance)
in the loop to enable
Hart communication.
