The DS215MSTCG5AZZ01A is a printed circuit board component fabricated by GE. This circuit board is typically used within the EX2000 excitation unit connected to the GE Mark V Speedtronic gas/steam turbine control system. The EX2000 is an excitation system using digital control that varies the output of the main generator using a microprocessor-based voltage regulating system. The connected MKV was one of GE’s later versions of their popular Speedtronic line, which began in the 1960s with the Mark I. While components for the MKV are no longer produced by the original equipment manufacturer, they are available from the AX Control inventory fully tested by our in-house technicians.
The DS215MSTCG5AZZ01A is fitted with two sets of standoffs to allow two optional auxiliary boards to be added to the motherboard if desired. The primary board is drilled at each corner to allow for mounting and is marked along its edges with letters/numbers to ease alignment.
The DS215MSTCG5AZZ01A is primarily populated by integrated circuits. This includes multiple field programmable gate arrays and EPROMs, as well as ICs designed to perform other tasks. Most ICs are marked on their upper surface with their original manufacturing codes for simple identification. Other board components include resistor network arrays, jumper switches, LED indicators, and various board connectors like vertical pin cable connectors and vertical header connectors. Technical support publications received with your OEM purchase will have additional information. This will include products like data sheets, user guides, and product manuals. GE provided the original technical support for MKV circuit boards.
