Digital I/O Termination Board GE DS200TBQBG1A for Mark V Series

GE DS200TBQBG1A Digital I/O Termination Module – Product Description

The GE DS200TBQBG1A module provides dependable termination points for digital signal wiring inside Mark V Speedtronic systems, ensuring stable connections for demanding turbine control environments. Moreover, its rugged construction and clean layout help technicians complete installation work quickly while maintaining consistent system integrity. The board supports multiple digital channels, and it integrates seamlessly with existing GE Mark V hardware without modification.

This module uses barrier-style terminal blocks that simplify field wiring and reduce the chances of signal noise during high-load operation. In addition, its isolation design enhances reliability by separating field signals from the backplane, protecting the control system during fluctuating electrical conditions. Engineers who require predictable performance in harsh sites often choose this module because it delivers consistent behavior across broad temperature ranges.
