• Operation
General
The ITXPlus is a DIN rail device that converts signals from commonly
used industrial signal sources and provides a fully isolated -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 generate power for the electronics. The ITXPlus requires a 10-0 V
drop to operate correctly. Using a power supply that provides this
voltage drop will comply with the instrument’s UL/CSA listing.
