IS220PDIOH1A Discrete Input/Output I/O Pack for Mark VIe Control Systems

The IS220PDIOH1A Discrete Input/Output (PDIO) I/O Pack is designed for GE Mark VIe control systems, providing a flexible interface between discrete field signals and the control system through compatible terminal boards. The module combines an embedded processor board with a discrete acquisition board, enabling digital signal monitoring and output control within distributed automation architectures.

The IS220PDIOH1A communicates with the Mark VIe controller through the IONet Ethernet network and interfaces with compatible terminal boards to process discrete field signals. Supporting both input and output functions in a single I/O pack, the module provides a practical solution for turbine control, industrial automation, and system maintenance applications where reliable discrete signal management is required.

• Combined Input and Output Capability: The IS220PDIOH1A integrates discrete input and output functions within a single I/O pack, allowing engineers to manage digital field signals through one standardized interface. This design helps simplify hardware selection and supports efficient system configuration.
• Reliable Communication Within Mark VIe Architecture: Through the IONet Ethernet communication network, the PDIO I/O Pack transfers field signal information between connected terminal boards and the Mark VIe controller. This distributed architecture supports flexible system layouts while maintaining compatibility with existing control platforms.
• Simplified Lifecycle Maintenance: The modular I/O pack design allows the IS220PDIOH1A to be replaced independently during maintenance activities. Using the correct GE Mark VIe-compatible module helps reduce system modification requirements and supports long-term operation of existing automation installations.
