About the DS200ACNAG1A
The DS200ACNAG1A, also known as ACNA, is an Attached Resource Computer Network Board from General Electric. Originally designed for the Mark V EX2000 subseries, it's also compatible with Mark VI and DC2000 Series lines.
The Mark V is GE's fourth commercially released Speedtronic system for heavy-duty turbines, featuring a triple-redundant microprocessor-based design for high reliability. Like other EX2000 legacy products, this ACNA module includes a direct sensor interface, built-in diagnostics, and online maintenance capabilities. The Mark V Series, and thus this board, applies to the control and management of wind, steam, or gas turbine automated drive assemblies. This DS200ACNAG1A ARCNET Board is a revised product, with its singular A-rated functional product revision distinguishing it from the original DS200ACNAG1 parent ARCNET Board.
DS200ACNAG1A ARCNET Connection Card Tips
- ARCNET systems, including the DS200ACNAG1A, operate at 2.5 Mbps, resulting in a signal network time of approximately 400 ns.
- This timing limits an ARCNET system's realistic length to four miles to prevent extended timeouts.
- The DS200ACNAG1A is a small circuit board with few components, including:
- Four metal film resistors (R1/R2/R3/R4)
- Two transistors
- One diode
- Three capacitors (C1/C2/C3)
- It has two metal-ringed openings (GND1 and GND2) on either side.
- The board's center contains two communications relay devices with printed relay diagrams.
- Additional components include a six-pin male vertical pin terminal connector and two female BNC plugs for LAN communications.
- Input Voltages Supported: Exciter Field Ground Detector Alarm, Malfunction, and Diode Fault voltages.
- Outputs: Handles up to four 4-20 mA outputs, provided via configurable digital-to-analog converters on the NTB/3TB board.
- Most applications can be achieved using the Status_S data link.
- Each DS200SDCIG1A Board (as per the attached datasheet) can terminate for two coaxial cables.
- The "A" in DS200ACNAG1A signifies its A-rated functional product revision, which may alter performance specifications or dimensions.
- The "G1" group designation indicates a normal-style protective PCB coating, which provides a thick protective layer.
- A full part number breakdown is available via the "manuals" tab for more details.
