High Density: The IS220PDIOH1B consolidates 32 channels into a 100mm x 150mm footprint, reducing panel space by 40% compared to legacy modules. A U.S. chemical plant achieved 25% cost savings on cabinet hardware after adopting this module.
Fault Tolerance: Its dual-channel redundancy design ensures continuous operation even if one channel fails. Field tests showed a Mean Time to Failure (MTTF) of 150,000 hours in harsh environments.
Flexible Configuration: Users can toggle between sourcing/sinking modes for digital outputs, adapting to various actuator requirements without hardware changes.
The IS220PDIOH1B is a high-performance digital input/output (DI/DO) module designed by General Electric (GE) for its Mark VIe and Mark VIIe control systems. This module plays a critical role in industrial automation, enabling reliable communication between field devices (e.g., sensors, valves, and motors) and the control system. With its advanced features and rugged design, the IS220PDIOH1B ensures seamless integration and efficient operation in industries such as power generation, oil & gas, and manufacturing.
1. Product Description
The IS220PDIOH1B is a compact, DIN-rail mountable module that supports up to 32 channels of digital inputs and outputs. It interfaces with both 24V DC and 120V AC signals, making it versatile for diverse applications. The module includes surge protection to guard against voltage spikes, optical isolation to prevent ground loops, and a status LED for real-time diagnostics. By integrating with GE’s Proficy software suite, the IS220PDIOH1B streamlines system configuration and reduces commissioning time.

6. Selection Recommendations
Signal Type: Confirm whether your application uses DC or AC signals, as the IS220PDIOH1B supports both.
Channel Count: Opt for this module if your project requires 16+ DI/DO channels in a compact space.
Cost Efficiency: While slightly more expensive than basic modules, its redundancy and long lifespan deliver a 25% lower lifecycle cost over 10 years.
7. Precautions
Installation: Use twisted-pair cables for signal lines to minimize EMI interference.
Maintenance: Replace the module every 10 years or after 100,000 operating hours for optimal performance.
Safety: Ensure the system is de-energized before replacing the module to avoid electric shock.
