The IS220PDIOH1A REV J is an advanced Discrete Input/Output (I/O) Module developed for use in the GE Mark VIe control systems, offering seamless integration and dependable control for turbine systems, plant automation, and industrial process operations. This versatile module features both discrete input and output capabilities, making it ideal for compact, space-sensitive applications requiring efficient signal interfacing.

The module operates with 24 VDC logic and includes optically isolated channels, protecting sensitive electronics from voltage spikes, noise, and external surges. This dual-function design reduces hardware requirements by allowing both types of discrete signals to be processed through a single unit. The IS220PDIOH1A is particularly well-suited for turbine protection systems, safety circuits, start/stop control, and process interlocks.

As part of the Mark VIe series, the IS220PDIOH1A features hot-swappable capabilities, allowing for replacement without shutting down the entire system—a critical feature for high-availability environments like power plants and offshore rigs. The device connects directly to GE’s terminal boards using plug-and-play connections, reducing installation time and ensuring wiring accuracy.

This module also includes built-in LED status indicators for each I/O point, making it easier for technicians to diagnose field signal status or troubleshoot faults. The embedded diagnostics communicate directly with the ControlST software suite, offering real-time health monitoring, logging, and maintenance support.

Built for durability, the IS220PDIOH1A REV J is constructed with high-quality industrial-grade components, ensuring optimal performance even in demanding ambient conditions, including high vibration and temperature zones.

Whether used in gas, steam, hydro turbines, or balance-of-plant applications, this module delivers robust performance with minimal downtime, making it a critical asset in any industrial automation system utilizing GE Mark VIe architecture.
