Functional Description

IS200TTRUH1C is a Terminal Board developed by GE. It is a part of Mark VI control system. The terminal board serves as the primary wiring connection point within the system, facilitating the distribution of signals to I/O board. Speed control systems for small turbines necessitate a streamlined system architecture. To achieve cost-efficiency and space savings, simplex control is implemented. Instead of the larger T-type terminal boards employed in TMR systems, compact DIN-rail-mounted terminal boards are utilized. Additionally, IONet is omitted as D-type terminal boards directly cable into the control chassis to interface with the I/O boards.

Role in Speed Control Systems

Small turbine speed control systems require a streamlined architecture to enhance cost-effectiveness and space efficiency. Instead of employing triple modular redundant (TMR) systems, which use larger T-type terminal boards, these setups incorporate simplex control for reduced complexity and improved affordability.

To further optimize space and simplify installation, the terminal board is DIN-rail mounted, allowing for compact and organized configurations. Unlike TMR-based systems that rely on IONet for data transmission, the D-type terminal boards are designed to connect directly to the control chassis via cabling, thereby eliminating the need for an additional communication network.

Signal Distribution and Connectivity

• Efficiently distributes signals to three separate DC-37 pin connectors, each corresponding to the R, S, and T I/O boards.
• These connectors serve as interfaces for cables linking the terminal board with the control system, ensuring reliable signal transmission.
• Different versions of this terminal board may include varied connector configurations to accommodate different I/O board types.

Variations in Terminal Board Design

Depending on the specific application and I/O board compatibility, variations of the terminal board exist with different layouts and functionalities:

• Basic Thermocouple Boards: Some thermocouple board versions do not include signal fan-out functionality and may feature only two connectors, enabling direct cabling to a single I/O board.
• Advanced Versions with Signal Fan-Out: Other versions are equipped with signal fan-out capabilities, featuring up to six connectors for connecting redundant R, S, and T I/O channels, enhancing system redundancy and signal integrity.

Circuitry and Components

• It primarily includes filters and protective components to prevent electrical noise interference and safeguard against voltage surges.
• This minimalistic approach reduces the risk of single-point failures, enhancing system reliability.
• Power for the output signals is generally supplied by the connected I/O boards.

However, in applications involving relay or solenoid outputs, the terminal board may include dedicated power plugs to provide a direct power source for these components.

Enhancing System Reliability and Performance

• Efficient signal distribution, reducing transmission errors.
• Compact DIN-rail mounting, optimizing space utilization.
• Protective circuitry, minimizing system failures due to electrical disturbances.
• Direct cabling to control chassis, eliminating the need for an additional communication network.
