IS220PIACH2A
GE
Overview
The IS220PIACH2A is an Analog I/O Module from GE. It is part of GE's industrial automation product portfolio.
Application & Technical Notes
As an analog i/o module, the IS220PIACH2A is intended for deployment in panel-based control cabinets and machine enclosures where the GE product portfolio equipment is installed. It performs a defined automation function within the control system and is selected to match the installed GE platform.
Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.
Maintenance & Diagnostics
Verify field wiring, shielding and grounding at installation; check terminal torque and confirm signal types match the configured range. Periodically inspect for loose terminations, induced noise and channel-level diagnostics reported by the controller. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the IS220PIACH2A, distinguish three supply tiers: (1) genuine GE stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Confirm the module matches your GE product portfolio rack, the required channel count, signal type and voltage, and the firmware/configuration of the controller. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications (source data)
About the IS220PAICH2A The IS220PAICH2A was manufactured by GE Energy for the Mark VIe Turbine Control System Series. The IS220PAICH2A is an Analog I/O Pack that works with a variety of different boards from the Mark VIe series.
Contextualized IS220PAICH2A Hardware The IS220PAICH2A acts as an electrical interface between one or two I/O Ethernet networks and an analog input terminal board. The IS220PAICH2A features a processor board and an acquisition board. The acquisition board is specific to the analog input function, whereas the processor board is standard for all Mark VIe distributed I/O packs.
The IS220PAICH2A can handle up to 10 analog inputs, with the first 8 able to be configured to +/- 5V or 10V inputs, or 0-20 mA current loop inputs. The final two inputs can be configured to +/- 1 mA or 0-20 mA current inputs.
Input is received through the RJ45 Ethernet connectors and a three pin power input. Output is through a DC 37 pin connector that is connected to the terminal board connector.
The IS220PAICH2A is equipped with several visual diagnostic LEDs. Some of these LEDs are:
PWR ATTN LINK There is also an infrared port that allows for local diagnostic serial communications.

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.
IS220PAICH2A Installation
Securely mount the terminal board of choice. Insert the PAIC I/O pack directly into the terminal board connectors. Use the threaded studs adjacent to the Ethernet ports to mechanically secure the I/O pack(s). The studs fit into a terminal board-specific mounting bracket. The bracket should be positioned so that no right-angle force is applied to the DC-37 pin connector between the I/O pack and the terminal board. The adjustment should only be needed once during the product's service life. Depending on the system configuration, connect one or two Ethernet cables. The I/O pack will function on either port. When using dual connections, it is common practice to connect ENET1 to the network associated with the R controller. Connect the I/O pack to power by plugging in the connector on the side of the pack. Because the I/O pack has inherent soft-start capability that controls current inrush on power application, it is not necessary to disconnect power from the cable before plugging it in. Configure the I/O pack as needed using the ToolboxST application.
