GE DS200SPCBG1A DS200SPCBG1AAA stores energy using two electrolytic capacitors. Together, they provide 220 µF at 35V rating for bridge excitation hold-up. This energy storage maintains sensor excitation during 25 millisecond power interruptions. Therefore, measurement data remains stable through brief voltage dips.
Design and Integration
Both the GE DS200SPCBG1A and DS200SPCBG1AAA versions share identical bridge conditioning circuitry. These boards use six-layer PCB construction with guarded analog traces for noise rejection. Consequently, the GE DS200SPCBG1A DS200SPCBG1AAA operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 350 mA typical current from the 24V DC supply. Each bridge input includes software selectable gain from 1 to 1000. We recommend using shielded twisted-pair cables for all sensor connections.
Practical Application
This signal processing board measures force, pressure, and torque from strain gauge sensors. It amplifies and digitizes each bridge input with high precision. The GE DS200SPCBG1A DS200SPCBG1AAA then sends digital data to the main controller via backplane. Therefore, it enables accurate load monitoring for turbine and drive systems.
