Technical Specifications: Input Signal Type: DC feedback analog signal from power‑unit loop Signal Processing: On‑board filtering, amplitude adjustment and signal isolation circuit Internal Bus: Mark V system internal back‑plane communication bus Operating Power Supply: Power obtained from Mark V chassis internal power‑supply bus Operating Temperature: 0°C to +60°C Storage Temperature: ‑40°C to +85°C Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard Mark V chassis plug‑in circuit board Certifications: CE, turbine‑control industrial EMC compliance
Functional Features: Receives and processes multi‑channel DC feedback signal from turbine power‑unit loop. On‑board filter circuit suppresses high‑frequency interference noise mixed in feedback signal. Signal conditioning and isolation circuit guarantee signal stability and anti‑interference capability. On‑board self‑diagnosis monitors feedback channel and on‑board hardware health status. Hot‑swap function is unavailable under system powered‑on running state.
Application Scenarios: GE Mark V gas‑turbine and steam‑turbine control system power‑unit feedback signal processing unit. Power‑plant turbine control cabinet spare‑part replacement and maintenance project. Legacy Mark V turbine control system renovation occasions.
Structural Characteristics: Standard plug‑in circuit‑board mechanical structure for Mark V dedicated chassis. Edge‑connector for interconnection with chassis internal back‑plane bus and power‑supply. External signal terminal interface for DC feedback‑signal wiring access.
Working Principle: DC feedback signal output from turbine power‑unit loop is sent into board via external terminal interface. Signal passes through filter circuit to eliminate interference noise. Conditioning and isolation circuit adjust signal amplitude and complete electrical separation.
Installation Requirements: Insert DS200DCFBG1BKC board into corresponding designated slot of GE Mark V standard chassis. Complete field DC feedback‑signal wiring on matched external terminal module. Cabinet grounding shall strictly follow turbine‑control system safety technical specification.
