More Information

Overview Manuals Compatibility Field Wiring Signal Processing Diagnostics

Features:

  • Provides twenty-four paired positive-and-return field terminations.
  • Routes contact states through JR1, JS1, and JT1 processor paths.
  • Places a chassis-grounded shield bar beside each barrier block.
IS200TBCIH1C uses external floating 125 VDC excitation to establish the sensing circuit for its dry-contact inputs.

The final three channels on IS200TBCIH1C use higher input current to support interfaces with remote solid-state output electronics.

IS200TBCIH1C consumes 20.6 W on the terminal board and has no jumpers or local hardware configuration settings.

The General Electric IS200TBCIH1C Contact Input with Group Isolation Terminal Board may be available for purchase and support from Apter Power for installed Mark VI or Mark VIe systems.

Control-System Interfaces

  • Mark VI: Molded cables connect IS200TBCIH1C to VCCC or VCRC processing boards.
  • Mark VIe: One, two, or three PDIA packs plug directly into the terminal board.
  • Redundancy: Mark VI supports simplex or TMR; Mark VIe also supports dual operation.
  • Revision C: The C board aligns JT1 with the Mark VIe I/O-pack support.

Terminal and Connector Layout

  • Field blocks: Two removable barrier blocks carry the twenty-four dry-contact circuits.
  • Contact pairs: Each input has one positive-source point and one return point.
  • Excitation: JE1 and JE2 connect the floating 125 VDC wetting source.
  • Conductors: Each terminal point accepts up to two #12 AWG wires with 300 V insulation.

Input-State Processing

  • Entry filtering: Each input includes surge and high-frequency noise suppression.
  • Hardware delay: A 4 ms filter rejects brief input transitions.
  • Threshold: The transition point tracks 50% of the applied floating supply.
  • Low-voltage clamp: Threshold tracking does not fall below 13% of nominal voltage.

Fault Detection Functions

  • Excitation monitor: A diagnostic is set if wetting voltage drops below 40% of nominal.
  • Input test: Forced-open checks detect channels that do not respond correctly.
  • Hardware identity: Connector ID data exposes board-type, revision, or location mismatches.
  • Cable status: The input system reports an unplugged processor connection.
Description
General Electric IS200TBCIH1C is a TBCI contact-input terminal board for Mark VI and Mark VIe turbine-control systems, providing field termination and conditioning for 24 dry-contact input circuits.

Two removable barrier blocks on General Electric IS200TBCIH1C land the 24 field contacts as paired positive and return points. A floating 125 VDC source in the 100–145 VDC range enters through JE1 and JE2; inputs 1–21 draw 2.5 mA, while inputs 22–24 draw 10 mA for interfaces with remote solid-state output electronics.

In a Mark VI installation, General Electric IS200TBCIH1C connects by molded cables to VCCC or VCRC processing boards and supports simplex or TMR signal paths. In Mark VIe, one, two, or three PDIA packs plug into JR1, JS1, and JT1 for simplex, dual, or TMR operation.

At each signal entry, General Electric IS200TBCIH1C applies surge and high-frequency noise suppression before the discrete voltage states pass toward optically isolated input electronics. The input system uses a 4 ms hardware filter and reports excitation loss, a nonresponding input during test mode, an unplugged cable, or a board-identification mismatch.

General Electric IS200TBCIH1C has no jumpers or hardware configuration settings. The terminal board consumes 20.6 W, operates from -30 to 65 °C, and accepts conductors up to #12 AWG at its field terminals.

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 control-system architectures can use General Electric IS200TBCIH1C?
In Mark VI, General Electric IS200TBCIH1C works with VCCC or VCRC boards in simplex or TMR arrangements; Mark VIe adds PDIA-based simplex, dual, and TMR paths.
How should the excitation circuit for General Electric IS200TBCIH1C be connected?
A floating 125 VDC source within the 100–145 VDC range connects to JE1 and JE2 on General Electric IS200TBCIH1C, with current limiting provided upstream in the power-distribution path.
What should be checked when General Electric IS200TBCIH1C reports invalid excitation voltage?
For General Electric IS200TBCIH1C, verify the wetting-power source and its wiring because the input system declares an excitation fault below 40% of nominal voltage.
Why do inputs 22–24 on General Electric IS200TBCIH1C draw more current?
General Electric IS200TBCIH1C assigns 10 mA loads to inputs 22–24 so those channels can interface with remote solid-state output electronics; inputs 1–21 draw 2.5 mA.
How does General Electric IS200TBCIH1C reject electrical noise on field contacts?
Near each signal entry, General Electric IS200TBCIH1C combines surge and high-frequency suppression with the input system’s 4 ms hardware filtering.
What identifies an incorrect board or connector match on General Electric IS200TBCIH1C?
Electronic ID data at the JR1, JS1, and JT1 paths lets the controller compare the type, revision, and connector location of General Electric IS200TBCIH1C and raise an incompatibility fault.
Does General Electric IS200TBCIH1C require jumper configuration?
No. General Electric IS200TBCIH1C has no jumpers or hardware settings; redundancy and input options are handled by the associated control configuration.
