GE DS200TCEAG1A Mark V Speedtronic Emergency Overspeed Board
The GE DS200TCEAG1A, also cataloged as the DS200TCEA Emergency Overspeed Board, operates as a dedicated hardware component for turbine overspeed processing and flame trip execution within Mark V Speedtronic platforms. Mounted in the dedicated <P1> protective core, the board processes speed signals and flame detector inputs via an onboard Intel 80196 microprocessor and multiple PROM memory modules to trigger hardwired protective trip sequences.

Deterministic Network Communications & Backplane Bus Velocity
The board interfaces directly with the Mark V protective core backplane to maintain strict backplane bus communication velocity across system control loops. Internal Intel 80196 microprocessor routines process frequency-based speed pulse inputs continuously while maintaining real-time logic synchronization with surrounding triple-modular redundant (TMR) cores. Furthermore, firmware flash compatibility across onboard PROM circuits guarantees fixed-latency trip output execution without introducing signal conversion delays across the system bus.
Frequently Asked Questions
Q: How are hardware hardware configuration parameters established on the DS200TCEAG1A board?
A: The board incorporates 30 onboard hardware jumpers that define signal routing paths, trip thresholds, and core interface selections prior to installation in the <P1> rack.
Q: What physical connectors are integrated on the front edge of the PCB assembly?
A: The board utilizes 2 bayonet connectors to establish direct, low-latency coaxial connections for speed sensor inputs and external protective signals.
Q: How does the DS200TCEAG1A board protect internal traces against overcurrent faults?
A: The printed circuit board assembly incorporates 3 replaceable onboard fuses to isolate internal power distribution paths from incoming field power surges.
Field Installation Guidelines
- Disconnect main power to the Mark V control cabinet and verify total voltage de-energization before inserting or removing the printed circuit board.
- Wear a grounded electrostatic discharge (ESD) wrist strap connected directly to the panel chassis ground during all board handling procedures.
- Verify that all 30 jumper positions match the original system engineering drawings before mounting the board into the <P1> protective core.
- Align the card edge connectors with the rack guide slots and push the assembly firmly into place until fully seated into the backplane socket.
- Secure all mounting hardware and connect both bayonet coaxial cables, ensuring tight mechanical locking to prevent signal degradation caused by field vibration.
