FUNCTIONAL DESCRIPTION:

IS200TBQGH1A is a Thermocouple Terminal Board manufactured by General Electric as part of the Mark VIe Series used in gas turbine control systems. A thermocouple terminal board is a device used in temperature measurement systems. Thermocouples are sensors that measure temperature based on the voltage difference between two different metals or alloys. The terminal board is where the thermocouple wires are connected and provides a convenient and organized way to interface with the measurement system. Key features of a thermocouple terminal board may include:

Interface Terminal Board: It serves as an interface for specialized turbine I/O application boards. It provides a connection point and facilitates the exchange of signals and data between the turbine I/O application boards and other system components. It acts as a central hub for managing input and output connections.

Box-Style Design: The board has a box-style design, indicating that it is a compact, self-contained unit. It is not removable, meaning it is permanently fixed in place once installed in the system.

Terminal Strip: The surface features a terminal strip with two levels of screw connectors. This strip provides the connection points for wiring the various components to the board. The terminal strip contains a total of sixty connectors, each serving as a terminal point for attaching wires. However, pins 53-60 are marked as unused and internally grounded, meaning they are not intended for external connections.

Box Resistors: Includes two box resistors, which are electronic components that provide resistance to regulate current flow or dissipate excess power. These resistors likely serve specific functions within the system, such as voltage regulation or current limiting.

Jumper Switches: Four jumper switches, labeled J1 through J4, are present on the board. Jumper switches are small devices that can be manually toggled to establish or interrupt electrical connections. The purpose of these jumper switches may vary based on the specific application or configuration requirements of the system.

Metal Oxide Varistors (MOVs): Near the connectors on the board, there are two lines of Metal Oxide Varistors (MOVs). MOVs are electrical components that protect against voltage surges or transients by rapidly diverting excessive voltage to the ground. Their presence on the board indicates a safeguard against potential electrical disturbances that could impact the connected components.

FREQUENTLY ASKED QUESTIONS:

How many connectors are on the terminal strip of the board?

The terminal strip has sixty connectors in total.

What are JUUR, JUUT, and JUUS on the board?

JUUR, JUUT, and JUUS are three male vertical pin connectors located one above the other on the right quadrant of the board.

What are MV29 through MV36 and MV1 through MV24?

MV29 through MV36 and MV1 through MV24 are metal oxide varistors (MOVs).
