I/O Density Scaling and VME Analog Signal Processing

The GE IS200BPAIH1ACB provides analog input interface functions within the Mark VI turbine control architecture. The board receives field sensor signals, performs signal conditioning and scaling, and transfers converted measurement data through the VMEbus backplane communication path.

The module supports I/O density scaling through configurable analog input channels and integrates with simplex or triple modular redundancy system structures. The onboard analog processing circuit provides filtering functions for low-level sensor signals before transmission to the control processor.

The VME backplane interface provides deterministic data exchange between the analog input board and the turbine controller. Firmware flash compatibility within the Mark VI platform determines supported controller communication and configuration functions.

Field Installation Guidelines

Install the IS200BPAIH1ACB in the designated GE Mark VI VME rack position and verify P1/P2 backplane connector alignment before applying system power.

Connect analog field wiring according to the configured input channel assignments. Use shielded instrumentation cables where required and terminate shields according to the turbine control cabinet grounding design.

Route analog signal wiring separately from high-voltage power conductors, relay circuits, and switching sources to reduce electromagnetic interference. Verify input polarity, signal range selection, and controller communication status during commissioning.
