Technical Specifications Signal: High‑precision analog output channels Bus Interface: Mark‑VI system backplane Operating Temperature:‑30℃ ~ +70℃ Mounting: Mark‑VI rack plug‑in structure
Functional Features High‑precision analog valve drive signal output Signal noise filtering and conditioning Channel fault self‑diagnosis and feedback
Application Scenarios Turbine governing control cabinet Mark‑VI speed valve actuator control subsystem
Performance Parameters High‑accuracy analog output adjustment Stable signal output under industrial electromagnetic interference
Structural Characteristics Standard Mark‑VI plug‑in circuit board Backplane high‑speed signal connector Front‑panel working and fault status LED lamps Rack locking mechanical latch
Working Principle Receives speed regulation instruction data from main controller through backplane bus. Converts digital commands into analog drive signals, and transmits output signals to turbine speed valve actuators to adjust turbine rotating speed.
Installation Requirements Wear anti‑static wrist‑strap throughout installation. Adopt shielded cables for valve actuator signal wiring. Ensure full insertion into rack slot.
Usage Notes Verify output signal range matches actuator rated parameters. Avoid heavy mechanical impact on circuit board components.
