Product Description

Overview

The GE IS220PDIAH1B I/O pack and IS230SNCIH2A terminal board operate together as a digital input subsystem for Mark VI and Mark VIe turbine control platforms. The pair captures critical field status signals and delivers them to the controller with consistent accuracy. Moreover, the subsystem supports stable communication in demanding environments where reliability and diagnostic visibility remain essential for daily operation.

The IS220PDIAH1B digitizes incoming contact signals, while the IS230SNCIH2A provides clean wiring paths and channel isolation. Therefore, users gain a dependable interface for digital status points such as breaker feedback, trip signals, permissives, and safety interlocks.
