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.

Signal Distribution

• Signals from the terminal board are distributed to three separate DC-37 pin connectors, each designated for cables connecting to the R, S, and T I/O boards.
• Different versions of the terminal board may feature varying combinations of connectors to accommodate specific requirements of different I/O boards.

Variations in Terminal Board Design

• Depending on the type of I/O board being used, the terminal board may feature different configurations.
• For instance, certain versions of thermocouple boards may not include signal fan-out functionality and may have only two connectors for cabling to a single I/O board.
• Conversely, other versions may include signal fan-out capabilities with six connectors designated for R, S, and T connections.

Circuitry and Components

• The terminal board typically incorporates minimal active circuitry, primarily consisting of filters and protective devices. This design minimizes the risk of potential single-point failures within the system. Additionally, power for the outputs is generally sourced from the respective I/O board.
• However, in cases involving relay and solenoid outputs, separate power plugs may be mounted directly on the terminal board to provide the necessary power supply.

Enhancing System Reliability

• By incorporating robust design elements and distributing signals efficiently, the terminal board contributes to the overall reliability and performance of the system.
• Its carefully engineered layout and integration of protective measures help mitigate risks associated with signal transmission and power distribution, ensuring seamless operation in various applications.

Features

• Constructed from polyester resin material rated for temperatures up to 130°C (266 °F).
• Terminal rating: 300 V, 10 A, UL Class C for general industry, with 0.375 inches of creepage and 0.250 inches of strike.
• Approved by UL and CSA codes.
• Screws feature a zinc clear chromate finish, while contacts are tin-plated.
• Each block screw is labeled with numbers 1 through 24 or 25 through 48 in white for easy identification.
• Recommended screw tightening torque: 8 in-lbs.
