The GE DS200TCPDG1BEC is a Power Distribution Module (Functional Acronym: TCPD) belonging to the General Electric Speedtronic Mark V Turbine Control System.1
This board’s essential role is to serve as the central power distribution and protection unit for the Mark V control architecture, ensuring that all vital system cores and modules receive stable electrical power.2
🔧 Technical Specifications & Features
The DS200TCPDG1BEC is located in the <PD> core of the Mark V panel and is a revised version of the original power distribution card.
Primary Functions
- Power Distribution: Distributes 3$125 \text{ VDC}$ power to critical components such as:4
- The Control Engine core.5
- The TCPS (Power Supply) boards in each I/O core.6
- The TCEA (Emergency Overspeed) boards in the protective
<P1>core.7
- Core Isolation/Control: It includes 8 toggle switches that enable operators or maintenance staff to independently power down each core for non-intrusive repair or diagnostics while the turbine is online (where applicable).8
- Protection: It manages circuit protection, especially for the high-reliability 9$125 \text{ VDC}$ circuits.10
Key Hardware Components
| Component | Quantity | Purpose |
| Fuses | 36 | Provides overcurrent protection for the 36 individual power circuits. |
| Status LEDs | 36 Green “OK” LEDs | Each fuse is monitored by a green LED. A lit LED indicates the fuse is intact and the circuit is healthy. |
| Toggle Switches | 8 | Used for manual power control and isolation of system cores. |
| Signal Terminals | 4 | For seamless connection to external devices and signal distribution. |
| Input/Output | $125 \text{ VDC}$ | The primary DC power distributed across the system. |
The “BEC” suffix indicates specific functional and artwork revisions on the board compared to earlier models, reflecting continuous design updates in the Mark V series.11
