About the DS200DCFBG2B

The DS200DCFBG2B is a DC Feedback Board by GE Mark V Turbine Control. This board, along with the newer Mark VI (DS200DCFBG2BNC), is the result of research and countless innovations so that these systems would be perfected. The Mark V Series that this DS200DCFBG2B printed circuit board is considered a member of is one of the final General Electric product series to incorporate their patented Speedtronic control system technology into its various product offerings, although it must be additionally considered a now-obsolete legacy product series due to its eventual manufacturing discontinuation in the many years following its initial release. This DS200DCFBG2B DC Power Supply and Feedback Card makes use of a normal Mark V Series assembly version as indicated by the presence of the DS200 series tag in the DS200DCFBG2B functional product number. This DS200DCFBG2B PCB is not the original product of its intended Mark V Series functionality, as evidenced by the presence of the final revision-indicating digit in its DS200DCFBG2B functional product number. The original DC Power Supply and Feedback Card manufactured for the Mark V Series is the DS200DCFBG2 parent printed circuit board.

Hardware Tips and Specifications

Introduced in 1991, the GE Mark V Turbine Control utilizes a TMR Microprocessor for sequencing, control, and protection. The board is also outfitted with VGA color graphics and a keyboard for an easy-to-use user interface. The DS200DCFBG2B sends and receives input and output signals using the equipped eighteen plug connectors and nine stab connectors.  The board’s stab connectors are located in the upper left corner and are labeled V1 through V3, P1A, P2A, VM1A , VM1B, VB2A and VM2BA. The plug connectors are spread throughout the entirety of the board and range from male 2 pin connectors to multi-pin connectors. This DS200DCFBG2B printed circuit board is a legacy series General Electric product, which means that its originally-introduced instructional manual materials may be shrouded in mystery, at least for the research purposes of this DS200DCFBG2B personalized product page. With this in mind, the DS200DCFBG2B printed circuit board does benefit from its original General Electric manufacture, as it possesses a DS200DCFBG2B functional product number displaying basic hardware component specifications in functional naming chunks. For example, the DS200DCFBG2B functional product number begins with the DS200 series tag delegating this DS200DCFBG2B PCB's normal Mark V Series assembly and domestic manufacture location. Some of the other hardware component and specification information revealed through the DS200DCFBG2B functional product number includes this DS200DCFBG2B Board's:

  • DCFB functional product abbreviation
  • Group 2 Mark V Series product grouping
  • Normal PCB coating style
  • B-rated functional product revision

The DS200DCFBG2B is outfitted with seven DIP switches, twelve jumpers, five TP test points, and three fuses. The fuses are for power supply protection. Indicators will light up should any of these fuses blow. There is one neon indicator and two which are LED lights. DIP switches are used to select AC line voltage and the voltage applied to the DC bridge voltage feedback VCO circuit as well as to the DC motor voltage feedback circuit. The DS200DCFBG2B is populated with various components, including seven transformers, oscillating chips, a relay, heat sinks, over fifty resistor network arrays, and various integrated circuits, capacitors, and resistors. The DS200DCFBG2B board uses CCR (carbon composite) resistors and resistors comprised of metal film material. GE provided technical support for the DS200DCFBG2B.  Please refer to manuals, data sheets or other publications for safety data relating to this part.

Frequently Asked Questions about DS200DCFBG2B

What does this DS200DCFBG2B device's normal PCB coating style entail?

This DS200DCFBG2B PCB's normal protective coating is a thick, rudimentary layer of chemically-applied PCB coating that envelops and protects individual DS200DCFBG2B hardware elements based on their functional priority.

Has this DS200DCFBG2B PCB's base circuit board been factory-drilled for installation purposes?

Yes. Several corners on this DS200DCFBG2B device's base circuit board have been factory-drilled and insulated to promote convenient and safe DS200DCFBG2B board installation and replacement.

Reviews For DS200DCFBG2B

Internal Review

In certain applications, the DCFB's AC input lines (L1 and L3) include ACCTs, or ac line current transformers. Make sure to switch SW7 on the board's surface to select burden resistance. ACCT signals are used to check commutation failure as well as instantaneous overcurrent. This DS200DCFBG2B printed circuit board has been edited from its originally-indicated performance specifications by the atypical B-rated functional product revision.
