Features:
- Separates protective terminations from the TCEA processing boards in the P1 core.
- Conditions generator voltage, bus voltage and line-current signals for the R5 core.
- Passes emergency-overspeed and flame-detection channels from PTBA to the three TCEA boards.
DS200TCEBG1B occupies location two of the P1 protective core, between field terminations and the processing boards.
Its PT and CT path reduces incoming measurement levels before forwarding them to TCCB for generator and bus functions.
The board also carries conditioned flame-detector power and contains the Mark V LM alarm horn.
The Mark V platform is no longer produced by GE; Apter Power may still support DS200TCEBG1B sourcing.

Protective Paths
- PTBA Input: JU receives overspeed-pickup and flame-detection signals from the terminal board.
- TCEA Outputs: JKX, JKY and JKZ feed the X, Y and Z protective processors.
- Measurement Input: JV brings PT and CT signals into the board.
- R5 Transfer: JMP carries scaled electrical measurements to TCCB.
Electrical Measurement Flow
- Voltage Sources: Generator and bus potential-transformer signals land at PTBA.
- Current Source: The line-current transformer path also reaches TCEB through JV.
- Level Reduction: The board steps the PT and CT signals down before transfer.
- Destination: TCCB receives the conditioned measurements for embedded functions.
Detector Supply and Return
- Signal Return: Flame-detection feedback enters through JU and proceeds to the TCEA boards.
- Supply Input: JWX, JWY and JWZ receive the 335 VDC source from the three TCEA boards.
- Conditioning: The high-voltage detector supply is conditioned on the expander board.
- Field Output: JVA delivers the conditioned 335 VDC path to PTBA and the UV flame detectors.
Fixed Board Setup
- Hardware Jumpers: No hardware jumpers are assigned to the TCEB board.
- Software Setup: The board has no software configuration.
- Horn Selection: The alarm-horn jumper is located on PTBA rather than TCEB.
- Unused Ports: JPU, JPV and JPW are normally not used.
