ITXPlus

• Operation

General

The ITXPlus is a DIN rail device that converts signals from commonly

ed industrial signal sources and provides a fully isolated 4-20 mA

signal that varies in proportion to the input signal.

Loop powered operation

Loop powered transmitters use the drop in voltage across the outputs

to g

enerate power for the electronics. The ITXPlus requires a 10-40 V

drop to operate correctly. Using a power supply that provides this

voltage drop will comply with the instrument’s UL/CSA listing.
