GE IS220PDIOH1A Product Specification
Product Overview
The GE IS220PDIOH1A is a discrete input/output (I/O) pack module designed for GE’s Mark VIe Speedtronic Turbine Control System, offering high-reliability digital signal processing in industrial automation. This module integrates 24 discrete inputs and 12 relay outputs into a single compact unit, making it ideal for applications requiring both signal acquisition and control in hazardous or non-hazardous environments
Key features include dual Ethernet ports (100 Mbps full-duplex) for high-speed communication with Mark VIe controllers, a local processor for real-time data processing, and 1500 Vrms optical isolation between channels and ground to prevent electrical interference 223. The module supports hot-swappable operation and front-panel LEDs for diagnostics (Power, Run, Fault, Ethernet links), enabling rapid maintenance in mission-critical systems
Constructed with a triple-layer conformal coating and IP20-rated enclosure, the IS220PDIOH1A withstands extreme temperatures (-30°C to +65°C), humidity (5–95% non-condensing), and vibration (75 G peak). Its VME 64x rack mount design (3U form factor) ensures compatibility with GE’s distributed I/O architecture

Key Features and Advantages
Flexible I/O Configuration:
The IS220PDIOH1A supports 24 discrete inputs (e.g., switch status, proximity sensors) and 12 relay outputs (e.g., solenoid valves, contactors), with selectable voltage ranges (24 VDC/125 VDC) for compatibility with diverse field devices 714. Its DC-62 pin connector interfaces directly with terminal boards (e.g., IS200TDBSH2A for simplex applications, IS200TDBTH2A for TMR systems), simplifying wiring and reducing installation time
