FUNCTIONAL DESCRIPTION:
IS230TBAI1CG is an Analog Input/Output Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Analog Input/Output (TBAI) terminal board can handle ten analog inputs and two outputs. The ten analog inputs support two-wire, three-wire, four-wire, and externally powered transmitters. The analog outputs can be configured for 0-20 mA or 0-200 mA current. Noise suppression circuitry protects the inputs and outputs from surges and high-frequency noise. TBAI includes three DC-37 pin connectors for connecting to I/O processors. Simplex applications are supported by a single connector (JR1). TMR applications are compatible with all three connectors. In TMR applications, input signals are routed to three connectors for the R, S, and T controls. TMR outputs combine the currents of the three connected output drivers to calculate the overall current using a measuring shunt.
INSTALLATION:
Connect the input and output wires to two I/O terminal blocks located on the terminal board. Each block has two screws and 24 terminals that accommodate wires up to #12 AWG. Each terminal block has an attachment point for the shield terminal. TBAI supports the following analog I/O types:
OPERATION:
TBAI supplies a 24 V dc power source for all transducers. Jumpers (J#A and J#B) allow you to specify the inputs as current or voltage. One of the two analog output circuits has a 4-20 mA range, while the other can be set to 0-200 mA. The following table shows the analog I/O capabilities of the TBAI. Each 24 V dc power output is rated to supply 21 mA continuously and is safeguarded against short circuits. Transmitters/transducers can be powered by the control system's 24 V dc source or by an external power supply. Jumper JO determines the type of current output. Diagnostics monitor each output, and a suicide relay in the I/O controller disconnects the relevant output.

What is IS230TBAI1CG?
The IS230TBAI1CG is an Analog Input/Output (TBAI) Terminal Board used in the GE Mark VIe control platform. It acts as a field interface board, connecting analog field devices such as transmitters and actuators to the control system’s I/O processor.
What analog signal ranges does the IS230TBAI1CG support?
The IS230TBAI1CG supports current inputs of 4-20 mA and voltage inputs of 0-10 VDC, as well as corresponding analog outputs. It is compatible with active and passive sensors, transmitters, and actuators. Input impedance is 250 ohms for current inputs and 10 k ohms for voltage inputs, ensuring minimal signal loading.
How many channels can be configured per board?
This terminal board supports up to 16 analog input channels and 16 analog output channels, depending on system configuration. Each channel is individually isolated to reduce crosstalk and prevent interference between signals. The update rate per channel is typically 10-20 ms, suitable for real-time DCS control loops.
How many I/O channels per board and system limitations?
The board supports up to 16 analog input channels and 16 analog output channels, with each channel individually configurable. The maximum load for outputs is 500 ohms for current outputs, 10 k ohms minimum for voltage outputs. Channels are designed to operate simultaneously without degradation, maintaining high-speed data throughput for all control loops.
