GE IS220PHRAH1A Product Specification
Product Overview
The GE IS220PHRAH1A is a high-performance process I/O module engineered for GE’s Mark VIe Speedtronic Turbine Control System, designed to bridge the gap between field sensors/actuators and the central controller in industrial automation. As a critical component in power generation, oil and gas, and heavy manufacturing, this module processes analog and digital signals to enable precise monitoring and control of key process variables—such as pressure, flow, and temperature—in gas turbines, steam turbines, and rotating machinery.
Integrated into the Mark VIe distributed architecture, the GE IS220PHRAH1A features 16 configurable I/O channels (8 analog inputs, 4 analog outputs, 4 discrete inputs) that support a range of signal types, including 4–20 mA, 0–10 VDC, and dry contact signals. Its 2500 Vrms galvanic isolation between channels eliminates electrical interference, ensuring accurate data transmission even in high-noise environments. The module’s compact 3U VME form factor (228.6 mm × 101.6 mm × 165.1 mm) and rugged construction—triple-layer conformal coating, IP20 enclosure—enable reliable operation in harsh conditions (-30°C to +65°C) with high vibration, humidity, and chemical exposure.
In automation systems, the GE IS220PHRAH1A acts as a versatile interface, translating sensor data into actionable commands for turbine governors, compressor anti-surge valves, and generator excitation systems. Its dual 100 Mbps Ethernet ports (IONET protocol) support redundant communication, ensuring uninterrupted data flow in safety-critical applications. Compatibility with IS230TCISH6C terminal boards allows deployment in hazardous locations (Class I, Division 2), adhering to strict safety standards for explosive atmospheres. The module’s hot-swappable design and advanced diagnostics further solidify its role as a reliable workhorse in mission-critical operations.
