Functional Description

IS200TBQBH1A is a Input Termination Module developed by GE. It is a part of Mark VI control system. The terminal board serves as a hub in the customer's wiring infrastructure, acting as the central connection point for various signals. Its primary function is to distribute these signals efficiently to three distinct DC-37 pin connectors, each leading to the R, S, and T I/O boards. Each type of I/O board possesses its own unique terminal board configuration, tailored to meet specific needs.

Features

• Signal Distribution: The terminal board plays a crucial role in fanning out signals to multiple I/O boards, ensuring that the right information is directed to the appropriate destination. This simplifies the wiring process and streamlines signal management.
• I/O Board Variations: Different types of I/O boards have their corresponding terminal boards, each designed to accommodate the specific needs of that board. For instance, certain versions of the thermocouple board may have only two connectors, simplifying cabling to a single I/O board, while others might fan out signals using six connectors for the R, S, and T channels.
• Fan Out Circuit: The fan-out circuit is a key component within the terminal board, responsible for branching signals to multiple destinations. It's worth noting that while efficient, the fan-out circuit presents a potential single point of failure, which underscores the importance of reliability in its design and construction.
• Active Circuitry: The terminal board is intentionally designed to minimize active circuitry, primarily incorporating filters and protective devices. This approach enhances reliability and reduces the risk of component failure. These passive components serve to maintain signal integrity and protect against electrical interference.
• Power Management: Typically, power for the outputs is sourced from the I/O board itself. However, for specific applications involving relay and solenoid outputs, separate power plugs are installed on the terminal board. This flexibility in power supply allows for tailored power management based on the specific requirements of different output types.

Frequently Asked Questions

 

What is IS200TBQBH1A?
It is a Input Termination Module developed by GE.

Why is the fan-out circuit mentioned as a potential single point of failure?
The fan-out circuit, which splits signals to multiple destinations, is considered a potential single point of failure because if it malfunctions, it can disrupt communication between the terminal board and the connected I/O boards.

What kind of active circuitry does the terminal board contain?
The terminal board is designed to contain a minimum of active circuitry. It primarily incorporates filters and protective devices. These components help maintain signal integrity and protect against electrical interference.

How is power typically supplied to the outputs connected to the board?
In most cases, power for the outputs is sourced directly from the connected I/O board. However, for specific applications involving relay and solenoid outputs, separate power plugs are mounted on the terminal board to provide dedicated power supply.
