About the DS200TCQBG1B

This DS200TCQBG1B Extended Analog I/O Board is a printed circuit board product offering that was originally manufactured for use in the Mark V Series. The Mark V Series that this DS200TCQBG1B printed circuit board belongs to has specific applications in the management and control systems of wind, steam, and gas turbine assemblies, and is considered a legacy series as it is no longer being actively manufactured by General Electric. While a legacy series, the Mark V Turbine Control System Series that this DS200TCQBG1B product offering belongs to is one of the more recently-developed General Electric product series utilizing their patented Speedtronic technology in its internal configuration. This DS200TCQBG1B printed circuit board or PCB for short is explicitly defined as an Extended Analog I/O Board in original General Electric Mark V Turbine Control System Series instructional manuals, although the original Mark V Series Extended Analog I/O Board developed was the DS200TCQBG1 parent printed circuit board missing this DS200TCQBG1B product's sole B-rated functional product revision.

Hardware Tips and Specifications

This DS200TCQBG1B printed circuit board, as with any product in the Mark V Series, is equipped with its own series of functionality-introducing hardware components and component specifications. For starters, the GE RST Extended Analog I/O Board DS200TCQBG1B is populated with a  programmable logic device and EPROM modules. It also has 1 OK LED that is viewable from the side, 1 50-pin connector, and 15 jumpers. When you obtain a replacement GE RST Extended Analog I/O Board DS200TCQBG1B it ships to you without erasable programmable read-only memory (EPROM) modules. The EPROM modules store the firmware and programming the logic device uses to process information. This represents about the extent of DS200TCQBG1B-specific information available in instructional materials compiled online. With that being said, the DS200TCQBG1B functional product number itself cna be considered a strong source of DS200TCQBG1B hardware component and specification information. The DS200TCQBG1B functional product number begins with DS200 series tag detailing this DS200TCQBG1B PCB's normal style of Mark V Series assembly and domestic location of original manufacture. Some of the other DS200TCQBG1B board-specific hardware traits revealed in the DS200TCQBG1B functional product number itself includes:

  • The TCQB functional product abbreviation
  • A normal style of printed circuit board protective coating
  • A Mark V Group One product grouping allegiance
  • A B-rated functional product revision

The EPROM modules can easily be removed from the old board and installed on the new board, although its pertinent General Electric manual materials are very specific in how this process should occur safely. Use a flat-blade screwdriver to pry the module off the socket. Use care to avoid hitting or scratching other components on the board while you remove the modules. Store the modules in a safe place until you need them. Wear a wrist strap whenever you work on the board or handle the modules, as the modules are sensitive to static and the information on them can be damaged. After you remove the modules put them in a static protective bag. As added protection, touch the bag to the exterior of the drive before you take out the modules; this enables the static to seek out the grounded metal surface of the drive and exit your person and the modules. When you install the modules in the new DS200TCQBG1B board, align the EPROM module with the socket and press straight down to install it. Visually inspect the connection between the module and the socket, as there should be no space between them. By using the same firmware and programming instructions, you can ensure that the new board will function the same as the old board, given that it possesses exactly the same style of B-rated functional product revision as this DS200TCQBG1B PCB.

Frequently Asked Questions about DS200TCQBG1B

What does this DS200TCQBG1B PCB's normal style of PCB coating entail?

The normal style of PCB coating applied to this DS200TCQBG1B product should exist as a thick rudimentary layer of daily wear and tear protection and circuit board insulation that envelops and protected individual hardware elements in this TCQB board's assembly based on functional priority.

What part of the DS200TCQBG1B functional product number reveals this Extended Analog I/O Board's B-rated functional revision?

The functional revision in the assembly of this DS200TCQBG1B printed circuit board is made apparent through the inclusion of the trailing B digit at the end of its DS200TCQBG1B functional product number.

Reviews For DS200TCQBG1B

Internal Review

While critical to Mark V applications, the DS200TCQBG1B Extended Analog I/O Board is has significant market availability and is generally a low cost PCB. The DS200TCQBG1B functions in conjunction with the TCQA Board and keeping a shelf backup of both boards on hand are ideal. Regardless, the TCQB is rarely found to be defective and the installation process if necessary is straightforward for any technician. A 5 Star designed board. - AX Control Lead Technician.
