More Information

Overview Manuals Core Feeds Diagnostics Fault Isolation Applications

Features:

  • Converts the TCPD 125 V DC feed into supply rails used inside a Mark V LM core.
  • Feeds processor, milliamp, RTD, servo-output, digital I/O, and ARCNET-related circuits.
  • Requires no hardware-jumper or software configuration.
DS200TCPSG1A is installed in the <R> core and in each of the four I/O cores. Its purpose is local power conversion and distribution rather than turbine-signal conditioning.

J1 accepts 125 V DC from TCPD. The 2PL path distributes converted supplies to boards in the core, while JP1 or JP2 serves TCDA and AAHA destinations.

JC provides diagnostic-voltage paths to TCQC or TCCA, and X1 connects to the CCOM bus.

After manufacturer End-of-Life (EOL), the General Electric DS200TCPSG1A Power Supply Board may still be sourced with supporting documentation through Apter Power.

Input and downstream paths

  • Input boundary: J1 is the 125 V DC input from the TCPD module in the <PD> core. Before investigating a low output rail, the supply at J1 should be distinguished from the converted voltages leaving the TCPS board.
  • Converted-supply paths: 2PL carries power-supply voltages to multiple boards in daisy-chain form. JP1 and JP2 are alternate connections for TCDA boards in Q11, Q21, and Q51 and for AAHA boards in the R core.
  • Localized symptom: A fault pattern limited to one destination can therefore point to its connector path rather than the entire DS200TCPSG1A conversion stage.

Where supply diagnostics are observed

  • JC routing: JC routes DS200TCPSG1A diagnostic voltages to TCQC in the R1, R2, and R3 cores. In the R5 core, the equivalent diagnostic destination is TCCA.
  • Core-specific monitor: This connector assignment matters when a voltage alarm is present: the monitoring board changes with the core, even though the local TCPS function is the same.
  • CCOM connection: X1 belongs to the CCOM connection and should be checked separately from the J1, 2PL, JC, and JP power paths.

Reading the failure pattern

  • Whole-core loss: If every board powered by one TCPS loses supply, start with the 125 V DC input at J1 and the protected conversion paths. If only a subset is affected, follow 2PL, JP1, or JP2 to that load group.
  • Downstream load: A low rail that remains after board replacement can be caused by a shorted or overloaded downstream circuit. Disconnecting only the affected load group helps separate the supply from the load.
  • Configuration limit: Because TCPS has no jumper or software settings, an unresolved output problem is not corrected by transferring configuration data.

Loads supported by TCPS

  • Generated supplies: The Mark V LM architecture uses TCPS-derived voltages for microprocessor circuitry and for supplies associated with milliamp outputs, RTDs, and servo-valve current outputs.
  • Core destinations: In the digital cores, JP1 or JP2 extends the supply path to TCDA. In the R core, the same connector choice supports AAHA boards.
  • Installed load mix: The installed core position and connector set define the actual load mix for a DS200TCPSG1A board.
Description
General Electric DS200TCPSG1A is the TCPS Power Supply Board installed in the Mark V LM R core and in each of the four I/O cores. It converts the 125 V DC input from TCPD into the voltage levels used by the electronics in that core.

The regulated supplies generated by DS200TCPSG1A support microprocessor circuits, milliamp output power, RTD excitation, and servo-valve current-output functions. Connector 2PL distributes these voltages to boards in a daisy chain, while J1 receives the incoming 125 V DC.

Through JC, DS200TCPSG1A sends power-supply diagnostic voltages to TCQC in the R1, R2, and R3 cores and to TCCA in the R5 core. JP1 or JP2 supplies TCDA boards in digital cores and AAHA boards in the R core; X1 connects the CCOM bus.

No hardware jumper or software setting configures DS200TCPSG1A; its operating state depends on the J1 input, protected conversion paths, connector destinations, and the regulated outputs required by its installed core.

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.
Why can several boards in one core fail at the same time with DS200TCPSG1A?
Those boards can share the DS200TCPSG1A supply path. Confirm 125 V DC at J1 and check the TCPS protected outputs before investigating every downstream board separately.
What should be checked when only part of a DS200TCPSG1A-powered core loses power?
Follow the affected destination through 2PL, JP1, or JP2. A connector or daisy-chain interruption can remove one group of loads while other DS200TCPSG1A outputs remain available.
Why does a DS200TCPSG1A power-supply diagnostic appear on TCQC or TCCA?
DS200TCPSG1A sends diagnostic voltages through JC. In the R1, R2, and R3 cores they are monitored by TCQC; in R5 they are monitored by TCCA.
What can cause a TCDA board to be unpowered while DS200TCPSG1A J1 still has 125 V DC?
The DS200TCPSG1A conversion stage or the JP1/JP2 distribution path may be interrupted. Check the protected supply output and the selected connector route to the digital core.
Why should a replacement DS200TCPSG1A not require jumper transfer?
GE documents no hardware-jumper or software configuration for the TCPS board. Correct core location, connector placement, and verified supply rails are the relevant installation controls.
What should be checked if a new DS200TCPSG1A shows the same low rail?
Verify the 125 V DC source at J1 and isolate the downstream load on 2PL, JP1, or JP2. A shorted or overloaded load can pull down the replacement supply as well.
How can a CCOM-related symptom be separated from a DS200TCPSG1A power-rail problem?
X1 is the CCOM connection, while the power paths use J1, 2PL, JC, and JP1/JP2. Check the required supply rails first, then evaluate the X1 communication connection independently.
How should DS200TCPSG1A revision ARE be identified in a sourcing request?
Use the complete DS200TCPSG1ARE marking and retain the RE suffix because it identifies the installed hardware revision.
