The Single Ended, Analog, Current Mode ITA is used only in
conjunction with the T7420 Analog Input Module when it is
employing a single ended current input wiring philosophy.
The ITA provides the facility for the current conversion
required. The ITA is capable of handling 16 single ended
signals.
Single ended I/O modules have 16 field circuits and one ITA
will be required for each module.
The connector idents are shown on the legend on the ITA.
The block diagram below shows typical connection of the
module to the field device.
