I/O Termination Assemblies (ITAs) are used in conjunction with I/O
modules to enhance the field wiring philosophy of the Regent + Plus
product range. The ITAs provide connector type conversion, analog
conversion, panel break facilities and an ideal point for test signal
injection. The ITAs can provide these facilities for all I/O modules with
the exception of the Thermocouple, RTU, Relay and Isolated Guarded
Output modules, which are wired in a conventional manner.

The ITAs provide rapid connection between I/O chassis and customer
field wiring, using pre-formed cables which are wired on a one to one
basis (ie. module pin 1 to ITA pin 1). A common supply path is
provided, allowing common field/return and analog conversion via
resistors.
