More Information

Overview Manuals Signal Paths Configuration Loop Verification Troubleshooting

Features:

  • Combines current-loop, temperature, and shaft-monitoring channels in the R5 core.
  • Interfaces separately with CTBA, TBQA, and TBCA terminal-board groups.
  • Transfers conditioned measurements to the I/O Engine through the 3PL data bus.
Uses Mark V software constants to assign sensor types, ranges, and scaling.

Unlike a general digital I/O card, General Electric DS200TCCAG1B must be validated channel family by channel family because each connector serves a different measurement path.

The installed General Electric DS200TCCAG1B configuration determines whether a point is interpreted as current, RTD, thermocouple, or shaft-monitoring data.

Terminal-board connections

  • JAA: Sends 4–20 mA outputs toward the CTBA terminal board.
  • JBB: Receives current inputs plus shaft voltage and shaft current from CTBA.
  • JCC and JDD: Carry the RTD channel groups from TBCA.
  • JAR/JAS/JAT: Accept thermocouple and cold-junction inputs from TBQA.
  • JC: Receives power-supply diagnostic information from TCPS.

Software values that define each channel

  • RTD setup: Choose the correct RTD curve and wiring arrangement for every resistance channel.
  • Thermocouple setup: Match thermocouple type, polarity, and cold-junction source to the installed terminal board.
  • Current scaling: Enter the correct 4–20 mA range and engineering-unit scaling for transducers.
  • Shaft assignments: Retain shaft-voltage and shaft-current monitoring assignments used by the turbine design.
  • Constant comparison: Compare saved I/O constants before accepting replacement-board measurements.

Functional checks after installation

  • Current loop: Inject or observe a known current value and compare the Mark V display with the field reference.
  • RTD channels: Check representative RTDs across JCC and JDD for open, shorted, and plausible readings.
  • Thermocouple path: Verify thermocouple polarity and cold-junction behavior at stable temperature.
  • Analog outputs: Confirm each analog output reaches the correct CTBA loop and external instrument.
  • Shaft monitoring: Review shaft-monitoring channels for offset, noise, and grounding problems.

Locating analog errors efficiently

  • One group failed: Start at its dedicated connector and companion terminal board.
  • All values frozen: Inspect 3PL communication, 2PL power, and board diagnostics.
  • Scaled value wrong: Compare I/O constants with sensor range and burden resistor.
  • Temperature offset: Check sensor type, lead wiring, polarity, and cold-junction input.
  • Noisy shaft signal: Examine shielding, grounding, CTBA connections, and cable separation.
Description
Analog conditioning for the Mark V R5 core is performed by the General Electric DS200TCCAG1B Common Analog Input/Output Board. It scales and conditions 4–20 mA signals, RTD inputs, thermocouple channels, shaft voltage, and shaft current before the values reach the I/O Engine.

Field circuits arrive at General Electric DS200TCCAG1B through CTBA, TBQA, and TBCA terminal boards. JAA carries current outputs, JBB accepts current and shaft-monitoring inputs, JCC and JDD carry RTD groups, and the JAR/JAS/JAT paths receive thermocouple and cold-junction information.

The 3PL data bus transfers conditioned values from General Electric DS200TCCAG1B toward STCA and the COREBUS, while 2PL distributes operating power from TCPS. Three hardware jumpers are reserved for the RS-232 test port, oscillator control, and factory testing.

Replacing General Electric DS200TCCAG1B requires more than matching the board code: the Mark V I/O configuration must retain the correct thermocouple types, RTD curves, milliamp ranges, shaft-monitoring selections, and connector destinations used by the unit.

Technical notes
DS200TCCAG1B exchange planning must preserve every analog scaling choice and the CTBA, TBQA, TBCA, 3PL, and 2PL connector map; board communication alone does not validate field measurement accuracy.

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 configuration must be saved before changing DS200TCCAG1B?
Export or record the DS200TCCAG1B thermocouple, RTD, milliamp, shaft-voltage, and shaft-current selections from the Mark V I/O configuration.
Why can one signal family fail while DS200TCCAG1B is still communicating?
A DS200TCCAG1B connector or companion terminal board can affect only its assigned signal group, so trace JAA, JBB, JCC/JDD, or JAR/JAS/JAT separately.
What should be checked when DS200TCCAG1B current outputs are incorrect?
Verify the DS200TCCAG1B JAA connection, CTBA field circuit, configured scale, loop load, and 4–20 mA output command.
How are RTD faults isolated on DS200TCCAG1B?
Identify whether the affected DS200TCCAG1B channels arrive through JCC or JDD, then check TBCA wiring, sensor type, excitation, and configuration.
Why can a thermocouple reading drift after DS200TCCAG1B replacement?
Check DS200TCCAG1B thermocouple type selection, cold-junction wiring from TBQA, connector placement, polarity, and channel scaling.
Should DS200TCCAG1B factory-test jumpers be moved during commissioning?
No. DS200TCCAG1B JP2 and JP3 are test-related positions; field setup should follow the board drawing and approved I/O configuration.
What proves DS200TCCAG1B is ready for service?
Compare live DS200TCCAG1B current, RTD, thermocouple, and shaft values with known conditions and confirm diagnostics and output-loop checks pass.
