Description Reviews

The GE IS200TBAIH1CDC, also cataloged as the IS200TBAI Analog Input Terminal Board, operates as a dedicated hardware component for analog signal termination within GE Mark VI Speedtronic turbine control system platforms. The board interfaces barrier-type field wiring with VAIC analog input modules, conditioning 10 analog inputs and 2 analog outputs across 1-5 VDC input spans and 4-20 mA loop circuits in simplex or Triple Modular Redundant (TMR) configurations.

Deterministic Network Integration and Backplane Processing

The IS200TBAIH1CDC transfers conditioned field signals to host processor racks maintaining backplane bus communication velocity across the Mark VI system architecture. In Triple Modular Redundant (TMR) setups, input signals from the terminal barrier are fanned to three separate control racks via JR1, JS1, and JT1 connectors. The onboard +24 VDC transducer power is diode-shared across connected VAIC boards to ensure fault-tolerant field loop powering and preserved firmware flash compatibility during online channel scanning.

Frequently Asked Questions

Q: How are analog input signals and transducer power routed in a TMR configuration?

A: Analog inputs are fanned to three VAIC modules across JR1, JS1, and JT1 cables. The +24 VDC transducer power supply originates from all three attached VAIC cards and is diode-shared on the terminal board to maintain field powering if a single module drops offline.

Q: What are the output load ratings supported by the IS200TBAIH1CDC?

A: The two analog output channels support a maximum load rating of 500 Ohms for standard 4-20 mA signal loops and 50 Ohms for higher current 0-200 mA drives.

Q: Can two IS200TBAIH1CDC terminal boards be connected to a single VAIC module?

A: Yes. A VAIC module supports up to two TBAI termination boards in combination, expanding total system channel capacity while maintaining deterministic signal conditioning.

Field Installation Guidelines

Mount the IS200TBAIH1CDC terminal board directly to the enclosure DIN rail or cabinet mounting plate using hardware standoffs to ensure proper grounding. Secure all field analog input and output wiring into the barrier terminal blocks, maintaining tight physical separation between low-level signal lines and high-voltage AC cables. Connect shielded cable drains to the cabinet earth ground bus bar at a single point. Verify that multi-pin ribbon or cable assemblies to the JR1, JS1, and JT1 ports on the primary VAIC modules are firmly locked before energizing the 24 VDC power supply.
