About the DS200ACNAG1A
The DS200ACNAG1A is an Attached Resource Computer Network Board from General Electric. Better known by the functional industry acronym ACNA, this board, while originally created as a component for the Mark V EX2000 subseries; is additionally compatible with the Mark VI and DC2000 Series lines. The fourth commercially released Speedtronic gas and steam turbine management system for heavy-duty turbines released by GE, the Mark V is a triple-redundant microprocessor-based system that achieves extremely high reliability rates due to the multiple backups on all critical controls and protection parameters. EX2000 legacy series products such as this ACNA module also tend to feature a direct sensor interface, built-in diagnostics, and online maintenance capabilities. The greater Mark V Series that this DS200ACNAG1A printed circuit board product offering belongs to has specific applications in the control and management systems of compatible wind, steam, or gas turbine automated drive assemblies, and is rated as a General Electric legacy product series given the eventual manufacturing discontinuation that took place in one of the many years after its initial series conception. This DS200ACNAG1A ARCNET Board is not the original product of its specific Mark V Series functional role; that would be the DS200ACNAG1 parent ARCNET Board crucially missing this DS200ACNAG1A PCB's singular A-rated functional product revision.
Hardware Tips and Specifications
It is important to note that conventional ARCNET systems, including this DS200ACNAG1A model, operate at a rate of 2.5 Mbps. This allows a signal on the network to happen in approximately 400 ns. This timing limits the size of an ARCNET system, which cannot, realistically, be longer than four miles; any longer than this, the system will begin to experience extended timeouts when messages are sent between nodes. The DS200ACNAG1A has very few components, considering its very small circuit board size. Some relevant components include:
- four metal film resistors (R1/R2/R3/R4,)
- two transistors,
- one diode,
- and three capacitors (C1/C2/C3.)
The board is built with two openings ringed with metal cut into either side of the card. These are marked as GND1 and GND2. The center of the board is populated by two communications relay devices. The top surface of both communications relay components are printed with relay diagrams. The last three components on the DS200ACNAG1A are a single six-pin male vertical pin terminal connector placed along the centerline of the board, and two female BNC plugs. These BNC plugs are designed to facilitate LAN communications. ACNA boards, including this DS200ACNAG1A model, are exceedingly stingy in the types of input voltages that they accept. This particular model of Mark V PCB supports input voltages including Exciter Field Ground Detector Alarm, Malfunction, and Diode Fault voltages; showcasing its true compatibility. In terms of outputs, this DS200ACNAG1A can handle up to four total 4-20 mA outputs; provided through the NTB/3TB board's digital to analog converters, which are considered configurable in terms of their software. Generally, most applications relevant to this DS200ACNAG1A ARCNET Board can be achieved through use of the attached Status_S data link. As specified in the DS200SDCIG1A data sheet attached in our convenient manuals tab above, each DS200SDCIG1A Board installed in the greater Mark V Series automated drive assembly can terminate for two total co-axial cables.
Before making an ultimate purchase decision of the DS200ACNAG1A, it is important to remember that this board component is functionally revised by a singular A-rated revision. This revision is revealed through an inclusion of the digit "A" following the "G1" group designation in the DS200ACNAG1A product number; and may change the performance specifications or even the overall dimensions of this model PCB. More information is collectible through a basic understanding of this part's product number. For example, the DS200ACNAG1A's "G1" group designation classifies it as a printed circuit board that makes use of a normal-style protective PCB coating. Normal PCB coating isn't as far-reaching in its total coverage as the alternative conformal coating, although it creates a much thicker PCB protective layer that should offer an unquestionable protective base for your industrial needs. A full part number breakdown for the DS200ACNAG1A is available above, through the "manuals" tab.
