IS200TBAOH1C - TBAO Analog Output Terminal Board | GE Mark VI | B7B

The General Electric IS200TBAOH1C (TBAO) is an Analog Output terminal board for GE SPEEDTRONIC™ Mark VI turbine control systems, supporting 16 current outputs in the 0-20 mA range. Current outputs are generated by the associated I/O processor board and TBAO includes noise suppression circuitry to protect against surge and high-frequency noise.

TBAO has two barrier-type terminal blocks for customer field wiring and six D-type cable connectors. In Mark VI systems, TBAO works with the IS200VAOC processor board and supports both simplex and TMR applications; in TMR configurations, TBAO is cabled to three VAOC boards using molded-plug cables to the VME I/O rack.

For maintenance and procurement teams, IS200TBAOH1C should be matched to the installed VAOC board generation, redundancy level, and terminal-board wiring per GEH-6421 Volume II before ordering a replacement.
