IS200TBAIH1B - TBAI Analog Input/Output Terminal Board | GE Mark VI | B7B

The General Electric IS200TBAIH1B (TBAI) is an Analog Input/Output terminal board for GE SPEEDTRONIC™ Mark VI turbine control systems, supporting 10 analog inputs and 2 analog outputs per board. Inputs accommodate two-wire, three-wire, four-wire, or externally powered transmitters, and the analog outputs can be configured for 0-20 mA or 0-200 mA current. Inputs and outputs include noise suppression circuitry for surge and high-frequency noise protection.

TBAI has three DC-37 pin connectors for connection to the I/O processor: a single connector (JR1) supports simplex applications, while TMR applications use all three connectors, fanning input signals to the R, S, and T controls and combining TMR output current through a measuring shunt. In the Mark VI system, TBAI works with the IS200VAIC processor and supports simplex and TMR configurations, with one or two TBAI boards connectable to a VAIC (three in TMR systems).

For maintenance and procurement teams, IS200TBAIH1B should be matched to the existing VAIC board generation and redundancy configuration per GEH-6421 Volume II before ordering a replacement.

Control system parts are provided by GTC Control Solutions, Inc., a wholly owned subsidiary of B7B. Parts are offered in unused, repaired, or remanufactured condition, subject to availability. Each repaired or remanufactured component undergoes functional testing in energized panels, with test reporting and warranty support provided for repair and lifecycle-extension programs.
