More Information

Overview Manuals Protection Signals Trip and Breaker Paths Flame and Alarm Product Applications

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.

  • 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.
Description
General Electric DS200PTBAG1B is a PTBA protection termination module used in the Mark V LM independent protection core. It terminates shaft-speed, flame-detection, generator and bus voltage/current, external-trip, emergency-trip and breaker-related field signals before they reach the associated protection boards.

DS200PTBAG1B separates these functions through named connector paths: JJR carries speed signals to TCQE, JM and JN exchange breaker and trip circuits with TCTG, and JU, JV and JVA connect overspeed, flame, alarm and PT/CT circuits to TCEB.

During DS200PTBAG1B service, preserve the TB1/TB2 terminal assignments, the destination of every inter-board connector and the J1 audible-alarm jumper position. The board is a field termination interface; retaining the wiring map is necessary before the protection core can be tested against the installed turbine records.

Technical notes
DS200PTBAG1B is a protection-core termination board, not the processor that executes turbine trip logic. Its field circuits route shaft-speed, flame, generator/bus voltage and current, breaker, horn, and trip signals to TCQE, TCEB, and TCTG. Replacement work must preserve terminal assignments and connector destinations before any protective-circuit test.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which signals terminate on DS200PTBAG1B?
It terminates shaft-speed, flame, PT/CT, breaker, external-trip, emergency-trip and alarm-related field circuits for the protection core.
Where do DS200PTBAG1B shaft-speed signals go?
The JJR connector routes the documented shaft-speed paths from PTBA to the TCQE board.
What is the difference between JM and JN on DS200PTBAG1B?
JM carries emergency-trip and breaker-related paths with TCTG, while JN carries the external-trip path including G125P.
What do JU, JV and JVA carry on DS200PTBAG1B?
JU carries overspeed, flame and alarm circuits; JV carries generator and bus PT/CT signals; JVA supplies flame-detector power.
What does jumper J1 control on DS200PTBAG1B?
J1 enables the audible alarm circuit. Its installed position should be recorded before service.
Does DS200PTBAG1B execute turbine trip logic?
No. It is a field termination interface; TCQE, TCEB and TCTG perform the associated protection processing.
What records should be captured before replacing DS200PTBAG1B?
Record TB1/TB2 assignments, connector destinations JJR/JM/JN/JU/JV/JVA, the J1 position and the complete board suffix.
