Functional Description

IS230TBAIH1C is a Analog Input/Output Terminal Board developed by GE. It is a part of Mark VIe control system. The board is designed to accommodate 10 analog inputs and 2 analog outputs. These inputs and outputs play a crucial role in transmitting and receiving analog signals for monitoring and control purposes. In TMR applications, the terminal board combines the current from the three connected output drivers and determines the total current using a measuring shunt. This total current signal is then presented to the VAICs for regulation to the commanded setpoint. This TMR configuration enhances system reliability and availability by providing redundant control signals and fault detection capabilities.

Features

• The 10 analog inputs are designed to accommodate different types of transmitters, including two-wire, three-wire, four-wire, or externally powered transmitters. This flexibility allows for seamless integration with a wide range of sensing devices, enabling accurate measurement and monitoring of various process parameters.
• The analog outputs can be configured to support either a 0-20 mA or 0-200 mA current range. This versatility allows for the selection of the appropriate output current range based on the specific requirements of the connected devices or control systems.
• To ensure reliable operation, both the analog inputs and outputs on the TBAI board are equipped with noise suppression circuitry. This circuitry provides protection against surge and high-frequency noise, minimizing signal interference and maintaining the integrity of the analog signals.
• The board features three DC-37 pin connectors for connecting Voltage-to-Current (VAIC) modules. In simplex applications, a single connector (JR1) is used to support the necessary connections. However, in Triple Modular Redundancy (TMR) applications, all three connectors are utilized. In TMR configurations, the input signals are distributed to the three connectors, designated as R, S, and T controls. This distribution ensures redundancy and enhances the fault tolerance of the system.

Installation

• The input and output wires are connected directly to two I/O terminal blocks mounted on the TBAI terminal board. Each terminal block is securely held in place with two screws, ensuring a stable and reliable connection. These terminal blocks are designed with 24 terminals, capable of accepting wires up to 12 AWG in size. This flexibility allows for the use of various wire gauges, accommodating different installation requirements.
• Adjacent to each terminal block on the TBAI terminal board, there is a shield terminal attachment point. This shield terminal provides a dedicated location for attaching and grounding shielded cables. By connecting the shield terminal to the corresponding shield wire, it helps minimize electromagnetic interference and ensures the integrity of the analog signals being transmitted.
• The TBAI terminal board is capable of accommodating various types of analog input and output configurations. Some of the supported analog I/O types include:
  • Analog input, two-wire transmitter: This configuration is suitable for connecting a two-wire transmitter to the TBAI terminal board, enabling the measurement and transmission of analog input signals from the transmitter.
  • Analog input, three-wire transmitter: This configuration supports the connection of a three-wire transmitter to the TBAI terminal board, allowing for the accurate measurement and transmission of analog input signals.
  • Analog input, four-wire transmitter: The TBAI terminal board can also accommodate the connection of a four-wire transmitter. This configuration ensures precise measurement and transmission of analog input signals from the four-wire transmitter.
  • Analog input, externally powered transmitter: For externally powered transmitters, the TBAI terminal board provides the necessary connections to interface with and receive analog input signals from these transmitters.
  • Analog input, voltage ±5 V, ±10 V dc: The TBAI terminal board supports analog input signals with voltage ranges of ±5 V or ±10 V dc. This configuration allows for the precise measurement and monitoring of analog signals within these voltage ranges.
  • Analog output, 0-20 mA: The TBAI terminal board can be set up to provide analog output signals in the range of 0-20 mA. This allows for the transmission of analog control signals within this current range to drive external devices or control systems.
  • Analog output, 0-200 mA: Similarly, the TBAI terminal board can be configured to provide analog output signals in the range of 0-200 mA. This wider current range allows for more versatile control signal transmission to meet specific application requirements.
• By supporting these various analog I/O types, the TBAI terminal board offers flexibility and compatibility with different transmitter configurations and control systems, enabling precise and reliable analog signal transmission and control.
