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.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
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.
