GE IS200HFPAG2A IS200HFPAG2ADB Printed Circuit Board – Mark VI Series

Technical Specifications

The GE IS200HFPAG2A (also IS200HFPAG2ADB) serves as a high-frequency power amplifier board. This board measures 30.5 cm in length and 25.4 cm in width. It weighs approximately 1.4 kg. The unit contains four independent amplifier channels for hydraulic valve control. A single 64-pin backplane connector provides system interface. Additionally, the board features one 9-pin D-sub port for external feedback signals. The GE IS200HFPAG2A IS200HFPAG2ADB stores 128 KB of calibration data in flash memory. It also holds no battery for energy storage. Instead, the board uses onboard capacitors for short-term hold-up.

Design and Integration

This GE IS200HFPAG2A IS200HFPAG2ADB drives hydraulic actuators in Mark VI turbine systems. Each amplifier channel accepts a control signal from the main processor. Then, the board converts it into a high-power output for servo valves. The four channels operate independently without cross-interference. Therefore, you can control multiple actuators simultaneously. The 9-pin D-sub port receives LVDT feedback for closed-loop positioning. For a different control component, see the RMS-TSG-TZ-C on Alibaba. However, that static trip relay handles protection rather than amplification.

Reliability and Operation

The GE IS200HFPAG2A IS200HFPAG2ADB operates from -20°C to +60°C. Its capacitor-based design eliminates battery replacement needs. Consequently, you reduce maintenance costs significantly. The board meets GE’s linearity specification of ±0.1% of full scale. Each unit undergoes 72-hour continuous load testing before shipping.
