Technical Specifications: Input Signal Type: DC feedback analog signal from turbine power‑unit loop Signal Processing: On‑board filter, amplitude adjustment and signal isolation circuit, variant‑version component configuration 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: Variant‑version multi‑channel DC feedback‑signal acquisition and processing for Mark V turbine power‑unit loop. On‑board hardware filter suppresses field‑loop high‑frequency electromagnetic interference noise. Special‑variant signal conditioning circuit matches corresponding power‑unit feedback‑loop parameter requirement. 
Application Scenarios: Specific variant‑loop matching for GE Mark V gas‑turbine and steam‑turbine control system power‑unit feedback processing. Power‑plant Mark V turbine control cabinet designated spare‑part replacement project. Legacy Mark V turbine‑control system renovation and component update occasions.
Structural Characteristics: Standard plug‑in circuit‑board mechanical structure for Mark V dedicated chassis installation. Edge‑connector for interconnection with chassis internal back‑plane bus and power‑supply. External signal terminal interface for DC feedback‑signal wiring access. PCB conformal coating for moisture‑proof and anti‑interference performance in power‑plant cabinet environment. Mechanical locking handle for board insertion‑extraction and fixing.
Working Principle: Field DC feedback‑signal from turbine power‑unit loop is transmitted to board via external terminal interface. Signal goes through filter circuit to remove high‑frequency interference noise. Special‑variant conditioning‑isolation circuit adjusts signal amplitude and completes electrical separation, matching corresponding loop parameter requirement.
Installation Requirements: Insert DS200DCFBG1BNC board into corresponding designated slot of GE Mark V standard chassis. Pay attention to variant‑model matching for original‑loop requirement. Complete field DC feedback‑signal wiring on matched external terminal module.
