General Electric IS200TBAIH2C Analog I/O Terminal Board

GE IS200TBAIH2C Analog I/O Terminal Board

The GE IS200TBAIH2C, also cataloged as the IS200TBAIH2C analog I/O terminal board, serves as the primary TBAI module used to execute mixed analog input and output signal conditioning across Mark VI and Mark VIe platforms.

Hardware Specifications

Backplane Bus Communication Velocity Licenses

As part of the GE Mark VI/VIe control architecture, the IS200TBAIH2C operates as a passive termination board supporting deterministic backplane timing. The board’s three DC‑37 connectors fan out analog signals to R/S/T processors in TMR configurations, maintaining synchronous acquisition cycles. When paired with IS220PAIC, firmware flash compatibility resides entirely in the I/O pack; the TBAI board contains no programmable logic. I/O density scaling is achieved through jumper‑selectable current and voltage modes, enabling consistent analog channel mapping across simplex and TMR installations.

Frequently Asked Questions

Q: Can the IS200TBAIH2C be hot‑swapped? A: No. The board must be replaced only with cabinet power isolated to prevent transient analog output disturbances.

Q: How does the board interact with IS220PAIC? A: The IS200TBAIH2C provides all analog termination and jumper configuration, while the IS220PAIC performs A/D conversion, linearization, diagnostics, and firmware‑level functions.

Q: What happens if the connector ID device mismatches? A: The I/O controller will report a hardware incompatibility fault and inhibit channel operation until the correct cable set is installed.

Field Installation Guidelines

• Maintain strict polarity discipline on all analog input and output wiring.
• Use shield bars on the left side of TB1/TB2 to terminate cable shields to chassis ground.
• Keep analog wiring isolated from high‑energy conductors to reduce induced noise.
• Verify jumper positions for each channel before commissioning to ensure correct current/voltage mode selection.
• Ensure all three DC‑37 connectors are fully seated in TMR systems to maintain synchronized R/S/T acquisition.
• Unplug barrier‑type terminal blocks only after confirming the board is de‑energized.
