Features:
- Protection-core termination for shaft-speed, flame, PT/CT, breaker and turbine-trip circuits.
- Named inter-board paths to TCQE, TCTG and TCEB through JJR, JM, JN, JU, JV and JVA.
- TB1/TB2 field termination and J1 audible-alarm enable configuration.
DS200PTBAG1B routes high-pressure and low-pressure shaft-speed signals from field wiring toward the TCQE protection path.
Separate connector groups retain emergency-trip, external-trip, breaker, flame and generator/bus measurement responsibilities.
The original terminal map and J1 jumper position are part of the installed protection-core configuration.
Apter Power supports official-document review, quotation coordination and sourcing enquiries for the General Electric DS200PTBAG1B Protection Termination Module.

- PTBA terminates high-pressure and low-pressure shaft-speed signals for the protection core.
- JJR sends the shaft-speed paths to the TCQE board for the documented Mark V LM arrangement.
- JU carries emergency-overspeed, flame-detect and audible-alarm enable signals to TCEB.
- JV carries generator and bus voltage plus PT/CT current signals to TCEB.
- JN routes external trip inputs between PTBA and the TCTG turbine-trip board.
- JM returns emergency trip outputs from TCTG through the PTBA field interface.
- Generator-breaker signal 52GL uses JM, while G125P is assigned to JN.
- Retain the JM and JN connector identities because the two paths serve different protection functions.
- JVA carries 335 V dc from TCEB to the connected flame-detection devices.
- Flame-detect signals return through the PTBA path to TCEB for protection processing.
- Hardware jumper J1 enables the audible alarm circuit; removing it silences the horn.
- Record the original J1 position and flame-detector wiring before replacing the termination board.
- Mark V LM independent-protection-core installations requiring a PTBA field termination interface.
- High-pressure and low-pressure shaft-speed pickup termination for overspeed protection paths.
- Flame-detector power distribution and flame-status routing through the protection core.
- Generator and bus PT/CT, breaker-close, external-trip and emergency-trip signal termination.
