Product Description

This DS200TCDAG1A printed circuit board was originally manufactured to exist as a member of the Mark V Series of turbine control systems, as explained above and in any pertinent General Electric instructional manual materials. This DS200TCDAG1A PCB has an official manual-defined functional product description as a Digital I/O Board, a fact that is reinforced by this DS200TCDAG1A PCB's TCDA functional acronym. This DS200TCDAG1A printed circuit board is not considered the original Digital Input/Output or I/O Board produced for General Electric's Mark V Turbine Control System Series, as it modified the original DS200TCDAG1 parent Digital I/O Board through its inclusion of an A-rated functional product revision.

Hardware Tips and Specifications

The General Electric DS200TCDAG1A Speedtronic Mark V LM Digital I/O Board is designed to process the digital contact input signals from the corresponding terminal boards in the application, and as such, is befitted with its own series of important and specific hardware components.The General Electric Digital I/O Board DS200TCDAG1A features one microprocessor and multiple programmable read-only memory (PROM) modules. It also contains 1 block made up of 10 LED lights and a pair of 50-pin connectors. The GE Digital I/O Board DS200TCDAG1A also is populated with 8 jumpers and 1 green LED that is visible from the side of the board. These mentioned PROM modules are removable from the board and they reside in a socket embedded on the board. When you want to replace the board or if you want to replace the PROM module for any reason, you can obtain a hand tool that is expressly designed for removing and installing the PROM modules. 

Several important connectors and jumpers exist in the assembly of this DS200TCDAG1A Mark V Series printed circuit board product. For starters, this DS200TCDAG1A Digital I/O Board has eight total significant hardware jumpers, each of which is accompanied by its own factory-printed nomenclature label. The J1 and J8-labeled jumpers in the assembly of this DS200TCDAG1A PCB are for factory testing purposes only. This DS200TCDAG1A PCB's J2 and J3 jumpers are included for the selection of IONET termination resistors. Jumpers J4, J5, and J6 in the assembly of this Mark V Series Digital I/O Board are for the selection of this PCB's IONET ID, while the final J7-labeled jumper in this DS200TCDAG1A PCB's assembly was included for stall timer enable selection. Contact inputs for the related Mark V Series DTBA and DTBB terminal boards interface using this DS200TCDAG1A Digital I/O Board's JR and JQ connectors, only two of the numerous different connector type available to this General Electric Speedtronic-driven product offering. All of the aforementioned hardware component inclusions and set specifications should be protected by this DS200TCDAG1A PCB's thick layer of normal-style PCB protective coating.

Frequently Asked Questions about DS200TCDAG1A

What does DS200TCDAG1A do for the contact inputs?
DS200TCDAG1A conditions the contact inputs for the digital I/O core. All digital inputs or contact inputs are terminated and conditioned in the digital I/O core and DS200TCDAG1A helps complete this process.
What needs to happen when DS200TCDAG1A is in a R control panel?
In a R control panel, two energize signals must be received by DS200TCDAG1A in order to energize a relay coil.
What are DS200TCDAG1A's connectors?
DS200TCDAG1A has 7 connectors. DS200TCDAG1A's connectors include: JP, JQ, JR, JO1, JO2, JX1, and JX2. For descriptions of each of DS200TCDAG1A's connectors, view section 5-4.6.1. in the Mark V LM Turbine Control Manual - Manual GEH-6353.

Reviews For DS200TCDAG1A

Internal Review

The GE DS200TCDAG1A Digital Input/Output Board is easily installed by the user after simply setting the configurable jumpers at J1-J8 and using the I/O Configuration Editor to modify contact input inversions. The board is well designed and has a low failure rate despite widespread use in Mark V LM Turbine Control Applications. This particular DS200TCDAG1A product offering features a standard Mark V Series assembly and is modified through the inclusion of a common A-rated functional product revision. - AX Control Lead Technician
