FUNCTIONAL DESCRIPTION:
IS230TBAOH1C is an Analog Output Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Turbine Control Systems. The Analog Output (TBAO) terminal board supports 16 analog outputs with a current range of 0-20 mA. Current outputs are generated by the I/O processor, which can be local (Mark* VIe control) or remote (Mark VI control). The outputs have noise suppression circuitry to protect against surge and high-frequency noise. TBAO has two barrier-type terminal blocks for customer wiring and six D-type cable connectors. In Mark VI systems, TBAO works with the VAOC processor and supports simplex and TMR applications. Cables with molded plugs connect TBAO to the VME rack where the VAOC board is located. In TMR systems, TBAO is cabled to three VOAC boards.
INSTALLATION:
Attach TBAO to a vertical mounting plate. Connect the wires for the 16 analog outputs directly to the two I/O terminal blocks mounted on the left of the board. Each point can accept two 3.0 mm (#12AWG) wires with 300 V insulation per point using spade or ring-type lugs. Each block is held down with two screws and has 24 terminals. A shield terminal strip attached to the chassis ground is located immediately to the left of each terminal block. Make cable connections to TBAO as follows:
OPERATION:
TBAO supports 16 analog control outputs. Driven devices should not exceed a resistance of 500 Ω (900 Ω if using I/O packs) and can be located up to 300 m (984 ft) from the turbine control cabinet. The VAOC or PAOC contains the D/A converter and drivers that generate the controlled currents. The output current is measured by the voltage drop across a resistor on the terminal board. Filters reduce high-frequency noise and suppress surgeon each output near the point of signal exit. In a TMR system, each analog current output is fed by the sum of the currents from the three I/O processors, as shown in the drawing below. The total output current is measured with a series resistor that feeds a voltage back to each I/O processor. The resulting output is the voted middle value (median) of the three currents.

How many analog control outputs does the terminal board support?
The terminal board supports a total of 16 analog control outputs. This allows for precise and flexible control over various external devices or processes.
What are the limitations of the driven devices connected to the analog control outputs?
The driven devices should not exceed a resistance of 500 ohms. However, if I/O packs are used, the resistance limit is increased to 900 ohms. Adhering to these resistance limits ensures the proper functioning and reliability of the analog control outputs.
What is the maximum distance between the turbine control cabinet and the driven devices?
The driven devices can be located up to 300 meters (984 feet) away from the turbine control cabinet. This extended distance allows for flexible placement of the controlled devices while still maintaining precise control from the central control system.
