GE Mark VI Analog Signal Interface Characteristics

The IS200TBAIH1CDD provides field wiring termination for voltage and current analog signals before transfer to the VAIC analog input/output board. The terminal interface maintains signal routing integrity between turbine sensors and the controller processing hardware.

GE Mark VI architecture uses VME-based backplane communication between control modules. The TBAI board functions as the field-side connection point, while the VAIC board performs analog conversion, scaling, and controller data processing.

Firmware and Backplane Compatibility

The board operates within the GE Mark VI control architecture through compatible VME rack interfaces. The module supports simplex and triple modular redundant configurations where multiple control paths require synchronized I/O signal availability.

The analog interface design supports I/O density scaling through Mark VI rack configurations, allowing multiple terminal boards and VAIC modules to be arranged according to turbine instrumentation requirements.

Frequently Asked Questions

Q: What analog signals can the IS200TBAIH1CDD terminate?
A: The board supports voltage and current analog signals including +/-5 V, +/-10 V, 0-1 mA, and 4-20 mA inputs, with analog outputs of 0-20 mA or 4-20 mA through the VAIC interface.

Q: Does the IS200TBAIH1CDD perform analog-to-digital conversion?
A: No. The terminal board provides signal termination and routing. Analog conversion functions are performed by the connected VAIC analog input/output board.

Q: Can the IS200TBAIH1CDD operate in redundant Mark VI configurations?
A: The board supports installation within simplex and TMR system configurations when used with compatible Mark VI control hardware.

Field Installation Guidelines

Install the IS200TBAIH1CDD in the designated GE Mark VI control cabinet location according to the system hardware configuration. Verify terminal assignments before connecting field wiring from analog sensors.

Use shielded instrumentation cables for low-level analog signals where required. Connect cable shields according to the cabinet grounding scheme and avoid routing analog signal cables parallel to high-current power conductors.

Confirm terminal polarity and signal type before energizing the system. Inspect connectors, terminal screws, and board seating condition during installation and maintenance activities.
