Key Features

1. Dual Function: Power Supply + Precision Feedback
   • Delivers regulated 24 VDC / 10 A control power for system logic, I/O modules, and panel cooling fans.
   • Conditions and processes high‑accuracy DC feedback signals (voltage, current, speed) from field sensors to the main controller.
2. BNC High‑Frequency Feedback Interface
   • Equipped with one 75 Ω BNC connector for clean, noise‑resistant transmission of high‑speed feedback signals (e.g., tachogenerator pulses).
   • Supports up to 10 kHz pulse input for precise speed and position monitoring.
3. Comprehensive Protection & Monitoring
   • Integrated over‑voltage, over‑current, and overload protection safeguards the board and connected drives from electrical faults.
   • Onboard fuses, LED/neon indicators, and five dedicated test points enable real‑time status monitoring and fast troubleshooting.
4. High Noise Immunity & Rugged Design
   • Multi‑layer PCB with EMC shielding suppresses EMI and RFI in high‑interference industrial environments.
   • Industrial‑grade components operate reliably from -40°C to +70°C and withstand vibration and shock.
5. Flexible Configuration & System Compatibility
   • 12 jumpers and 7 DIP switches allow precise configuration of input ranges, feedback scaling, and operating modes.
   • Fully compatible with GE Mark V drives (FC2000, AC2000, DC2000, ME2000, CB2000) and turbine control systems.
6. Simplified Installation & Maintenance
   • Standard 124 × 185 mm form factor fits directly into GE control cabinets with secure mounting points.
   • Clearly labeled jumpers, test points, and status LEDs reduce setup and diagnostic time.
