GE DS200TCEAG1B DS215TCEAG1BZZ01A stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for trip memory retention. Consequently, the board maintains fault status during 20 millisecond power interruptions. Therefore, overspeed trips remain latched through brief voltage dips.
Design and Integration
Both the GE DS200TCEAG1B and DS215TCEAG1BZZ01A versions share identical overspeed logic. These boards use four-layer PCB construction with guarded analog traces for noise rejection. Consequently, the GE DS200TCEAG1B DS215TCEAG1BZZ01A operates reliably from -15°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 150 mA typical current from the 24V DC supply. Each input channel includes overvoltage protection up to 100V peak. We recommend using shielded twisted-pair cables for all speed sensor connections.
Practical Application
This overspeed board monitors turbine shaft speed using three independent magnetic pickups. It trips the unit immediately when detecting speed above the setpoint. The GE DS200TCEAG1B DS215TCEAG1BZZ01A also provides voting logic (2 out of 3) for high reliability. Therefore, it ensures safe turbine overspeed protection in GE control systems.
