GE VVIB-H1C IS200VVIBH1CAC VVIB Vibration Monitoring Input Board

GE IS200VVIBH1CAC is a revised version vibration signal acquisition processing board under GE IS200 series, specially configured for GE Speedtronic Mark VI turbine control system. 

It receives analog signals from vibration probes via DVIB or TVIB terminal boards, completes signal filtering, conditioning and high-precision analog-to-digital conversion, 

then transmits processed vibration data to main controller through VME backplane bus. It monitors casing vibration, rotor eccentricity, differential expansion and axial displacement,

 realizes turbine over-vibration interlock protection and equipment condition monitoring, serving as core safety spare part for gas & steam turbine unit maintenance.
