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.
