About the DS200DDTBG2ABB

The DS200DDTBG2ABB is an LCI Auxiliary I/O Terminal Board. This PCB was created as a component for the Mark V system from GE. The Mark V was the second of the Speedtronic gas and steam turbine management systems to offer triple redundant back-ups on critical controls and protection parameters. This DS200DDTBG2ABB board's Mark V product series also includes features such as built-in diagnostics, online maintenance, and a direct sensor interface. The DS200DDTBG2ABB PCB featured on this personalized product page is actually not the original LCI Auxiliary I/O Terminal Board manufactured for placement in the larger Mark V Turbine Control System Series; that would be the DS200DDTBG2 parent printed circuit board missing all three of this DS200DDTBG2ABB product's significant product revisions.

Hardware Tips and Specifications

The DS200DDTBG2ABB is a high voltage board. Its function is to create system connections for auxiliary I/O signals. Given this specific intended Mark V Turbine Control System Series functionality, it should come as no true surprise that this DS200DDTBG2ABB product offering makes use of its own elevated series of functionality-encouraging hardware components and component specifications. The DS200DDTBG2ABB board receives power from and is connected to the DS200ADMA board, which is a daughterboard module located on the DS200DSPC digital signal processor control board.The DS200DDTBG2ABB is built with multiple inputs and outputs. These outputs include high voltage AC inputs (2,) high current signal inputs (6,) low current signal inputs (3,) 4-20 mA current loop inputs (up to 2,) and undedicated voltage inputs. The current loop inputs in this DS200DDTBG2ABB LCI Auxiliary I/O Terminal Board's assembly are reassigned from the CT or LEM input channels using jumpers. The DS200DDTBG2ABB board featured here also has four buffered analog outputs and two 4-20mA current outputs. The board also has sixteen digital Input/Outputs. 

The DS200DDTBG2ABB PCB is built with 33 TP test points, used for signal measurement, as well as 17 LEDs (DS1-DS17.) The board includes twelve jumper switches with 3 positions each. The factory setting for these switches is on the 1-2 position. In terms of standard voltage-limiting hardware components, the DS200DDTBG2ABB LCI Auxiliary I/O Terminal Board makes use of two transformers, four relays, and fourteen transistors. The DS200DDTBG2ABB uses capacitors and resistors as well, and features an assembly secured by the normal style of PCB coating that it has been chemically-treated by. This DS200DDTBG2ABB Mark V Series product's internal assembly also has eight varistors and fifteen resistor network arrays. Finally, this DS200DDTBG2ABB printed circuit board has five terminal strips that vary from three screw positions to thirty-six screw positions, and has many integrated circuits, including a chip with board identification and hardware revision information. More information on the board functions, application data, features, and installation can be found in GEI-100219, a publication from General Electric that may be hard to retrieve through the internet given this DS200DDTBG2ABB product's series as a Mark V legacy series product offering. Before making a final purchase decision on this DS200DDTBG2ABB high-voltage LCI Auxiliary I/O Terminal Board, it is crucial to realize that its originally-introduced performance specifications and dimensions have been impacted through its inclusion of a full product revision table with two functional product revisions and an artwork configuration revision.

Frequently Asked Questions about DS200DDTBG2ABB

Which Mark V Series product group does this DS200DDTBG2ABB LCI Auxiliary I/O Terminal Board belong to?

This DS200DDTBG2ABB printed circuit board belongs to the relatively-uncommon second grouping of GE Mark V Series products, as evidenced by the inclusion of the G2 series grouping tag in the DS200DDTBG2ABB functional product number.

Would this DS200DDTBG2ABB LCI Auxiliary I/O Terminal Board be protected by any warranty following my original purchase?

Yes. Immediately upon your original purchase here at AX Control, this DS200DDTBG2ABB PCB and many other General Electric printed circuit boards would be deemed protected under our three-year guaranteed PCB warranty.

Reviews For DS200DDTBG2ABB

Internal Review

This MK V LCI Aux. I/O board has twelve jumper switches that are divided into four groups: JP1-3, JP4-6, JP7-9, and JP10-12. When you are setting up the board, you must make sure all three jumpers in a group are in the same position. This DS200DDTBG2ABB printed circuit board is a Mark V Series group 2 product with a full revision history including two functionality-aimed product revisions and an artwork revision. - AX Control Lead Technician
