DS200ACNAG1ADD

About the DS200ACNAG1ADD

• The DS200ACNAG1ADD is an ARCNET (Attached Resource Computer Network) Card manufactured by General Electric for their Mark V series.
• The Mark V is part of GE’s successful Speedtronic line of gas/steam turbine management systems.
• This series has managed heavy-duty turbines since the 1960s, with the Mark V featuring:
  • Triple-redundant backups on all critical controls and protection parameters.
  • Built-in diagnostics.
  • Online maintenance.
• This specific DS200ACNAG1ADD is a revised product; the original DS200ACNAG1 parent printed circuit board lacks its three significant revisions.

Hardware Tips and Specifications

• The DS200ACNAG1ADD provides a connection point for ARCNET LAN communications within the Mark V system.
• Signals travel between the main processor board (LDCC) and the turbine control operator interface via coaxial cables.
• It's a small circuit board with few components, including:
  • Four metal film resistors (R1 through R4).
  • Three capacitors (C1 through C3).
  • One diode.
  • Two factory-drilled holes with metal washers (GND1/GND2).
  • Two relays near the bottom edge, each with a relay diagram.
  • Three communication devices:
    • A vertical 6-pin terminal connector in the center.
    • Two right-angled, female BNC plugs at the top edge for LAN coaxial cables.
• Due to its obsolete status, much hardware information comes from visual inspection and its part number.
• The DS200ACNAG1ADD functional product number indicates:
  • Its domestic manufacturing location.
  • Normal Mark V Series assembly style (from the DS200 series tag).
  • ACNA functional product abbreviation.
  • Normal style of PCB coating.
  • Group one Mark V Series product grouping.
  • Full three-fold revision history (two functional product revisions and an artwork configuration revision).
• Be aware that the three significant revisions have likely altered the original performance specifications and dimensions of this board.
