Product Overview

The GE IS220PDIAH1A is a discrete contact input terminal board used to terminate and route field wiring for contact-status signals in GE control architectures. In practical cabinet builds, this board is installed as the field-interface point for discrete inputs and is used together with compatible discrete input I/O packs (commonly the YDIA family) to deliver reliable on/off status data into the control system.

As a terminal board, the IS220PDIAH1A is focused on clean wiring termination, signal distribution, and maintainable cabinet layout rather than executing control logic. Correct matching of the terminal board and I/O pack helps ensure consistent signal conditioning and dependable status acquisition in industrial environments.

Hardware Parameters

Key Technical Characteristics

• Field wiring termination board for contact input signals used in control and protection cabinets

• Designed for I/O pack pairing to support stable discrete input acquisition (pack selection depends on system configuration)

• Cabinet maintainability with structured terminal layout to simplify commissioning and troubleshooting

• Industrial PCB assembly intended for control-panel environments with typical vibration and electrical noise exposure

• Revision-managed part identification to support consistent replacement in installed systems

Industrial Applications

• EX2100 excitation control panels requiring discrete status wiring termination

• Turbine and generator auxiliary monitoring such as breaker status, alarms, permissives, and cabinet switches

• Plant retrofit and maintenance where original terminal board form/fit is required for wiring compatibility

• Spares programs supporting long-life industrial control cabinets and installed GE platforms
