This board integrates over 110 discrete components onto a multi-layer PCB. Its dimensions measure roughly 7.5 inches wide by 6.0 inches high. The total weight reaches about 0.48 kilograms including the protective coating. Four LVDT input channels connect directly to linear position sensors. Four DC output channels send proportional voltage signals to the controller. One backplane connector provides power and data paths to the main rack. The design stores up to 210 joules of capacitive energy for stable transducer excitation.

Functional Layout and Signal Conditioning

The GE DS200AAHAH2A DS200AAHAH2ADC conditions LVDT signals with high accuracy and linearity. Each conditioner generates an AC excitation signal for the transducer. Moreover, the board demodulates the return signal into a DC voltage proportional to position. This variant includes upgraded demodulators for better linearity and temperature stability. General Electric specifically designed this transducer board for the Mark V Speedtronic system. You can replace an older board with this unit without changing the rack configuration.

Installation Guidelines and Compatibility

This LM transducer board mounts directly into a standard Mark V rack slot. Always disconnect system power before handling the GE DS200AAHAH2A DS200AAHAH2ADC. The board works with existing GE Mark V backplanes and LVDT sensors. Verify your firmware revision supports this variant. This board maintains backward compatibility with earlier Mark V versions. Proper installation ensures accurate position feedback and system integrity.
