GENERAL ELECTRIC IS220PAICH2A Analog I/O Module

GE    IS220PAICH2A Analog I/O Module

Specification

Details

IS220PAICH2A is an analog I/O module developed by General Electric. It is a part of the Mark VIe Speedtronic control system.

This I/O pack is directly attached to the terminal board. The I/O pack is connected to the simplex terminal board via a single DC-37 pin connector.

If only one I/O pack is installed, the TMR-capable terminal board has three DC-37 pin connectors and can be

used in simplex mode. All of these connections are directly supported by the I/O pack.

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.
