IS220PAICH1B Analog I/O Pack Module Description

The IS220PAICH1B Pack Module is an Analog Input/Output (I/O) Pack designed and manufactured by General Electric (GE) as part of the Mark VI Series Turbine Control System.

 IS220PAICH1B Pack Module is the second version (V2) of the PAIC units, featuring a different minimum operating voltage than its predecessor.

 The IS220PAICH1B Pack Module number itself encodes key hardware information through a series of functional naming chunks. 

Due to the discontinuation of the Mark VI series, official technical documentation for this device is scarce.
