IS220PAOCH1A is an Analog Output Module manufactured by General Electric as part of Mark VIe used in gas turbine control management systems.

An electrical interface between one or two I/O Ethernet networks and an analog output terminal board is provided by the Analog Output (PAOC). 

A BPPx processor board and an acquisition board pair tailored to the analog output function are both present in the PAOC. 

Up to eight simplexes, 0-20 mA current loop outputs can be provided by the PAOC, which also has an analog to digital converter for each output's current feedback. 

Dual RJ-45 Ethernet connectors and a three-pin power input serve as the PAOC's inputs. 

The related terminal board connector is directly connected to the output via a DC-37 pin connector. 

Indicator LEDs are used to display visual diagnostics.

Functional Description

The Analog I/O pack (PAIC) is an electrical interface that connects one or two I/O Ethernet networks to an analog input terminal board. 

The PAIC includes a BPPx processor board as well as an acquisition board dedicated to the analog I/O function.

The module has ten analog inputs. The first eight inputs can be set to 5 V or 10 V or 4-20 mA current loop inputs. 

The final two inputs can be set to 1 mA or 4-20 mA current inputs.

The load terminal resistors for current loop inputs are located on the terminal board, and the PAIC senses voltage across these resistors. 

PAICH2 has two current loop outputs ranging from 0 to 20 mA.

 It also includes additional hardware that allows for 0-200 mA current on the first output only.

The I/O pack receives and sends data to the controller via dual RJ-45 Ethernet connectors and is powered by a three-pin connector. 

Field devices are communicated with via a DC-37 pin connector that connects directly to the associated terminal board.

LED indicator lights provide visual diagnostics.
