GE  DS200ACNAG1ACC  Mark V control series cards

Series to which it belongs: Mark V is a gas/steam turbine management system developed by GE in the 1990s and is part of the Speedtronic series. This series has been used to manage heavy turbine systems since the 1960s. Mark V has functions such as online maintenance of its triple redundant controller, full turbine generator monitoring, digital valve positioning and enhanced diagnosis, which can help technicians isolate faults to the card level.

Function and purpose: As an ARCNET card, it mainly provides connection points for ARCNET LAN communication within the Mark V system. It receives the signals from the autonomous Processor Board (LDCC) and transmits them to the turbine control operator interface. Vice versa, the signals are transmitted through coaxial cables. In addition, it has also established a data link connection with the turbine controller.

Hardware specifications: This is a small circuit board with few components, including three capacitors (C1, C2 and C3), four metal film resistors (R1, R2, R3 and R4), one diode and two relays. Each relay has a printed relay diagram on its surface. There are also two factory-made openings on the circuit board, with metal rings inserted inside, marked as GND1 and GND2. There are two right-angle female BNC plugs at the top edge for connecting LAN coaxial cables, and a 6-pin vertical pin male connector at the center position.
