FUNCTIONAL DESCRIPTION:

IS230TBAI is an Analog Input/Output (TBAI) 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 supports 10 analog inputs and 2 outputs. The 10 analog inputs accommodate two-wire, three-wire, four-wire, or externally powered transmitters. The analog outputs can be set up for 0-20 mA or 0- 200 mA current. Inputs and outputs have noise suppression circuitry to protect against surge and high-frequency noise. TBAI has three DC-37 pin connectors provided on TBAI for connection to the I/O processors. Simplex applications are supported using a single connector (JR1). TMR applications are supported using all three connectors. In TMR applications, the input signals are fanned to the three connectors for the R, S, and T controls. TMR outputs combine the current of the three connected output drivers and determine the total current with a measuring shunt. TBAI then presents the total current signal to the I/O processors for regulation to the commanded setpoint.

INSTALLATION:

Connect the input and output wires directly to two I/O terminal blocks mounted on the terminal board. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wires. A shield terminal attachment point is located adjacent to each terminal block. TBAI can accommodate the following analog I/O types:

• Analog input, two-wire transmitter
• Analog input, three-wire transmitter
• Analog input, four-wire transmitter
• Analog input, externally powered transmitter
• Analog input, voltage ±5 V, ±10 V dc
• Analog output, 0-20 mA
• Analog output, 0-200 mA

OPERATION:

TBAI provides a 24 V DC power source for all the transducers. The inputs can be configured as current or voltage inputs using jumpers (J#A and J#B). One of the two analog output circuits is 4-20 mA and the other can be configured as 4-20 mA or 0- 200 mA. The following table displays the analog I/O capacity of TBAI. Each 24 V dc power output is rated to deliver 21 mA continuously and is protected against operation into a short circuit. Transmitters/transducers can be powered by the 24 V DC source in the control system or can be independently powered. Jumper JO selects the type of current output. Diagnostics monitor each output and a suicide relay in the I/O controller disconnects the corresponding output if a fault cannot be cleared by a command from the processor.

CONFIGURATION:

The terminal board is configured by jumpers. For the location of these jumpers, refer to the installation diagram. The jumper choices are as follows:

• Jumpers J1A through J8A select either current input or voltage input.
• Jumpers J1B through J8B select whether the return is connected to common or
• is left open.
• Jumpers J9A and J10A select either 1 mA or 20 mA input current.
• Jumpers J9B and J10B select whether the return is connected to common or is left open.
• Jumper J0 sets output 1 to either 20 mA or 200 mA.

FREQUENTLY ASKED QUESTIONS:

What is a TBAI Terminal Board?

A TBAI Terminal Board, or Analog Input/Output Terminal Board, is a device used in electronics and automation to connect analog sensors and actuators to a control system. It facilitates the transfer of analog signals, such as voltage or current, between the field devices and the control system.

What is the purpose of a TBAI Terminal Board?

The primary purpose of a TBAI Terminal Board is to provide a convenient and organized way to interface analog devices with a control system. It helps in signal conditioning, isolation, and signal amplification when necessary.

What are some common applications of TBAI Terminal Boards?

TBAI Terminal Boards are commonly used in industrial automation and process control systems to connect sensors like temperature sensors, pressure transducers, and flow meters to programmable logic controllers (PLCs) or distributed control systems (DCS).
