The IS220PDIOH1A, REV D is a high-performance Discrete Input/Output (I/O) Module developed specifically for GE Mark VIe turbine control systems. It delivers reliable and efficient signal processing for up to 24 VDC input/output signals and is capable of managing various field-connected devices such as solenoids, relays, switches, and contact sensors.

With its dual functionality, the IS220PDIOH1A streamlines system design and reduces the need for separate input and output modules. The I/O channels are optically isolated to prevent signal degradation and offer protection from electrical surges and noise—ensuring operational integrity even in harsh industrial settings. The module supports both sourcing and sinking configurations and integrates directly with GE’s I/O packs and terminal boards.

Each I/O channel on the IS220PDIOH1A is equipped with optical isolation, which ensures robust signal integrity and protection against voltage transients and electrical noise commonly encountered in industrial environments. The module supports 24 VDC logic levels, offering compatibility with standard control voltage levels used in turbine and plant systems.

The IS220PDIOH1A, REV D module is an integral component of the GE Mark VIe control system, providing highly dependable discrete input and output functionality. Designed to interface with a wide range of field devices, it efficiently processes both digital input signals (such as status indicators, pushbuttons, and limit switches) and output signals for actuating relays, solenoids, and alarms. Its compact design consolidates both input and output functionality into a single unit, making it ideal for applications where space and modularity are critical.

It is hot-swappable, allowing for system maintenance without requiring shutdowns. Diagnostic LEDs provide real-time status on I/O states and health monitoring, aiding in fast troubleshooting and reduced downtime. Designed for DIN rail mounting, the IS220PDIOH1A ensures a compact installation footprint while maintaining excellent thermal and signal performance.

This module is ideal for power generation facilities using GE Mark VIe systems, especially in turbine control, auxiliary equipment automation, and plant-wide digital signal integration.
