IS200PSCDG1A | General Electric Speedtronic Turbine Control Board Mark VI

The IS200PSCDG1A is a printed circuit board (PCB) component manufactured by General Electric (GE) for use in the Mark VI system, a part of the Speedtronic line. This line represents GE’s advanced series for managing gas and steam turbines, continuing the lineage that began with the Mark I in the 1960s and concluded with the Mark VIe over three decades later. The Speedtronic systems are known for their reliability in turbine control, with the Mark VI system featuring Ethernet communications, a central Control Module that can be configured as either Triple Redundant or Simplex, and an Operator Interface based on a Windows PC pre-loaded with proprietary software, including CIMPLICITY graphics for turbine management. 

The IS200PSCDG1A does not include a front faceplate and is marked for alignment on two edges, with letters on one edge and numbers on the other. The board is identified by the round GE logo, board identification number, and reference designators to facilitate component identification. 

The board is equipped with ten heat sinks, primarily positioned at the top. It contains several high-voltage electrolytic capacitors as well as capacitors made from ceramic and polyester vinyl materials. Additionally, the board features three inductor coils, four transformers, five light-emitting diodes (LEDs), two metal oxide varistors, six fuses, and multiple transistors.
