Overview

The IS220PAICH1B is a second-generation analog I/O pack from GE’s Mark VI turbine control series. It is engineered to deliver accurate and reliable analog signal acquisition and transmission. Designed for both hazardous and non-hazardous industrial environments, this module supports multiple terminal board options and provides diagnostic capabilities to ensure system integrity.

Key Technical Specifications

• Ambient Operating Temperature: –40°F to 158°F (–40°C to 70°C)

• Analog Transmitter Power: 22.8 VDC

• Nominal Power Supply: 24V or 28V DC

• Minimum Voltage Requirement: 22.5 VDC

• Delta Method: Percentage of Configured Span

• Wire Requirements: Minimum 22 AWG (when connected via IS200TBAIH1C terminal board)

Compatible Terminal Boards

The IS220PAICH1B pack is compatible with the following GE IS200 terminal boards:

• IS200TBAIH1C (Barrier-type terminal board)

• IS200TAIH1A

• IS200TAIH2A

Pack Diagnostics & Alarms

Alarm 66–67:

• Description: Individual output current is too high relative to the total current.

• Indicates: Potential signal imbalance or malfunction.

Alarm 82–83:

• Description: Suicide relay is non-functional.

• Possible Causes:

• Mismatch between relay command and feedback

• Hardware failure

• Acquisition board relay failure

• Recommended Action: Replace the I/O pack

Product Notes

• The IS220PAICH1B is a successor to the IS220PAICH1 and differs in minimum voltage requirement and revision.

• While part of the Mark VI platform, its legacy also aligns with the Mark V turbine control system architecture.

• This module is part of a broader GE control ecosystem and integrates easily with legacy and modern systems alike.
