The IS220PDIAH1A, REV C is a robust and highly efficient 24-point discrete contact input I/O module designed specifically for the GE Mark VIe control system platform. It is used in gas and steam turbine applications, as well as other industrial environments that require precise monitoring and reporting of on/off signals from field devices.

Each of the 24 channels on this module is independently isolated and capable of detecting standard contact inputs from field devices like limit switches, pushbuttons, relays, and proximity sensors. With quick response times and reliable input signal recognition, the IS220PDIAH1A ensures high-speed monitoring for safety interlocks, alarms, and status feedback mechanisms.

The REV C version improves upon previous revisions by delivering enhanced protection against electrical transients, robust diagnostics, and increased reliability. This includes features like open/short detection and per-channel health monitoring, which aid in preventive maintenance and reduce downtime.

Designed with a compact DIN-rail mountable form factor, the IS220PDIAH1A is hot-swappable and supports rapid deployment or replacement without system reboot—ensuring continued operations with minimal interruption. It interfaces directly with GE Mark VIe I/O packs, making it ideal for seamless integration into existing systems.

In environments where reliable discrete input monitoring is essential—such as power generation, petrochemical, and industrial automation—this module provides the durability, compatibility, and flexibility demanded by mission-critical applications.
