GE DS200TCPDG1A Power Distribution Board

Configured for 125 VDC power distribution and circuit protection in Mark V Speedtronic turbine control platforms, the GE DS200TCPDG1A (DS200TCPDG1 Power Distribution Board) provides direct physical/electrical execution.

Hardware Specifications

Backplane Bus Communication & Firmware Integrity

The DS200TCPDG1A board distributes bus power across individual control cores via hardwired trace paths and backplane interconnects, ensuring firmware flash compatibility and stable operation across all connected Mark V modules. High-density power routing channels are protected against over-current faults through individual fused branch circuits. Manual toggle switching allows independent core isolation without disrupting control bus backplane integrity across adjacent triple modular redundant (TMR) processing cores.

Frequently Asked Questions

Q: What operational voltage and power distribution functions does the DS200TCPDG1A perform?

A: The board receives and distributes 125 VDC bus power to individual control cores (R1 through R5 and P1 X/Y/Z) within the Mark V Speedtronic turbine control panel.

Q: How do the onboard diagnostic LEDs indicate the operational status of the 36 individual fuses?

A: Each fuse circuit is monitored by a green OK LED that remains illuminated when the fuse is intact. Two additional red LEDs illuminate when a branch fuse opens to indicate a blown circuit fault.

Q: What is the technical purpose of the BJS jumper on the DS200TCPDG1A circuit board?

A: The BJS jumper is configured to isolate the internal board ground reference from chassis ground when integrating with systems requiring an external ground reference.

Field Installation Guidelines

• Mount the board inside the designated Mark V turbine control cabinet card cage slot using anti-static handling procedures, ensuring all nylon retaining standoffs lock securely into place.

• Route 125 VDC power supply cables to the board terminal connections, maintaining strict physical separation from low-voltage I/O and communication cables to avoid noise coupling.

• Verify that the BJS jumper position matches the site-specific ground reference design prior to applying control power.

• Connect a dedicated cabinet grounding braid from the card rack chassis directly to the primary enclosure earth bus bar to ensure proper surge voltage protection and EMC noise suppression.
