Product Introduction
GE DS200TCPDG1BEC is a power distribution board for the GE Speedtronic Mark V control system family. It is designed to distribute power to circuits and modules within the Mark V turbine control architecture and provide visible fuse-status indication for maintenance and troubleshooting.
The board is equipped with 36 fuses housed in black plastic canisters. Each fuse is positioned vertically inside its canister for easy replacement. The canister top rotates to open and remains attached, so the cap does not get lost during maintenance. Each fuse has an associated green status LED; when the LED is on, the fuse element is intact, and when it is off, the fuse is blown or the board is not powered.
The board also includes 8 toggle switches, 36 normal-status LEDs, 4 signal wire terminals, and one 10-pin connector. Because public documentation for the exact DS200TCPDG1BEC suffix is limited, the detailed power distribution map, toggle switch functions, 10-pin connector pinout, and signal terminal assignments should be verified from the physical board label and GE Mark V manuals before installation.
Some third-party listings describe DS200TCPDG1BEC as a digital output module, servo terminal board, or PLC controller. Those descriptions conflict with the TCPD power distribution board definition and should not be treated as authoritative without verification against the physical board label and GE documentation.

Note: The TCPD power distribution function, 36 fuses, 36 LEDs, 8 toggle switches, 10-pin connector, and 4 signal terminals are documented for the DS200TCPDG1BEC. The exact power distribution map, toggle switch functions, LED assignment, fuse ratings, and connector pinout should be verified from the physical board label and GE Mark V manuals.
Quality Control Process (DYNAMIC GENERATION)
- Visual and label inspection. We check the part number, suffix, PCB surface, fuse canisters, LEDs, toggle switches, 10-pin connector, and signal terminals for damage or corrosion.
- TCPD function verification. We confirm the board matches the DS200TCPDG1BEC power distribution board description and is not mislabeled as a digital output, servo, or PLC module.
- Fuse and LED check. All 36 fuse canisters and LEDs are inspected; blown fuses are documented and replaced only with correct-rated fuses.
- Toggle switch and connector check. All 8 toggle switches and the 10-pin connector are verified for correct position and pin continuity.
- Final packaging. After passing inspection, the board is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Confirm TCPD function before installation. DS200TCPDG1BEC is a power distribution board; do not substitute it with TCQA, TCEB, SLCC, SDCC, or other Mark V I/O boards.
❗ Ignore conflicting third-party descriptions. Some listings describe this part number as a digital output module or servo terminal board; that conflicts with the TCPD power distribution board definition.
❗ Match fuse ratings exactly. Replace fuses only with the same rating; do not bypass or substitute with higher-rated fuses.
❗ Record toggle switch positions before removal. Document all 8 toggle switch positions for correct restoration after replacement.
❗ Label all connectors and signal terminals. Miswiring the 10-pin connector or signal terminals can cause incorrect power distribution or system faults.
❗ Check LED status before removal. Document which LEDs are on/off for troubleshooting reference after replacement.
❗ Handle as ESD-sensitive equipment. Always use anti-static wrist straps and handling procedures during removal, installation, and storage.
Keep these in mind and you’ll cut 90% of rework time.
