GE DS200ITXDG1ABA Dynamic Brake Buffer Plate

About the DS200ITXDG1ABA

The DS200ITXDG1ABA board is labeled as a Dynamic Brake Buffer Board and

is part of the Mark V Series manufactured by General Electric.

The Mark V Series, of which this DS200ITXDG1ABA product is a part,

was one of the last of General Electric's Mark product line to incorporate

Speedtronic control system technology into its various products.

And since it was eventually discontinued many years after its initial release, it exists as a legacy product line.

This DS200ITXDG1ABA Printed Circuit Board, or PCB for short, is not an original development for

its specific Mark V Turbine Control System family of functional roles;

it is actually the DS200ITXDG1 Parent Dynamic Brake Buffer Board.

The DS200ITXDG1ABA PCB is conspicuously missing all three versions

of the three important product versions of the DS200ITXDG1ABA PCB.

The assembly of this DS200ITXDG1ABA PCB has been specifically

altered to utilize a Level A Major Function Revision, a Level B Minor Function Revision, and a Level A Drawing Configuration Revision.

Hardware Tips and Specifications

The required operation of the IXTD board is provided through the circuitry

of the connected power supply/interface board (IMCP).

When the IMCP and the IXTD board are connected, they are connected via a four-pin connector.

When the board is installed, it will be externally mounted and must

be sized to meet the worst-case switching requirements of dynamically braked IGBTs.

The purpose of the snubber board is to be used to limit voltage transients

at both ends of the IGBT and at all known operating conditions of the driver.

Another function of the DS200ITXDG1ABA board is to regulate the output

of the IGBT gate driver board to match the electrical characteristics of the AT frame driver.

AT frame drivers are available in variable and constant torque applications.

The drive output current rating for variable torque applications is 500 ARMS.

The DS200ITXDG1ABA board has three connector types: bus I/O connectors,

input connectors for DBPL, and board pin connectors.

All of these connector types have different pin numbers, nomenclature,

and descriptions, which are explained in depth and in detail in the 

DS200ITXDG1ABA instruction manual included above for your convenience.

Bus I/O connectors and pin I/O connectors are also oriented. 

Two examples of pins associated with the stab I/O connectors are the

E-6 and E-9 connectors, both of which are output connectors.

The E-6 connector is the DB IGBT gate signal and the E-9 connector is the connection for the external buffer resistor.

The single plug-in connector that can be used to assemble this DS200ITXDG1ABA Dynamic

Braking Buffer Board is also fully discussed in the associated General Electric instruction manual material.

This connector is accompanied by a DBPL factory printed naming label and

connects this DS200ITXDG1ABA product to the accessible IMCP cousin PCB product in the larger Mark V series automatic drive assembly.

For convenience, the plug-in connector location for this DS200ITXDG1ABA PCB is described separately in the available guidance material.

Before making any single final purchase decision on this DS200ITXDG1ABA Dynamic Brake Buffer Board,

it is important to realize that it was originally designed to be used as a dynamic brake buffer board.

It is important to realize that the performance specifications and dimensions it

was originally introduced with have undoubtedly changed as a result of its receiving a full triple revision history.

The ITXD board allows for adjustment of the various outputs in the Mark VI series.

There are three different connector types on the board, allowing the board to be connected in a variety of different ways.

This DS200ITXDG1ABA printed circuit board product or PCB for

short has the normal style of Mark V series assembly, although it has been edited

by accepting the full range of three Mark V series feature and illustration configuration product revisions.
