The IS200BPIBG1A is a GE printed circuit board component that acts as a Phase Logic module within the Mark VI series. The Mark VI is one of the later Speedtronic systems for gas and steam turbine management released by General Electric. These systems have been used for heavy-duty turbine management since the late 1960s.
The IS200BPIBG1A is designed to capture faults found by the Gate Driver boards and report those faults to the boards that will process them. Some faults are processed by the IS200BPIBG1A. The board is also used to provide signal conditioning to interface P1 connector logic signal controls to Shunt Feedback and Gate Driver boards.
The IS200BPIBG1A is designed with a narrow black front faceplate. This board has the GE logo imprinted on it. The IS200BPIBG1A is designed to plug into a VME type rack. This happens via the P1 connector located on the rear edge of the board. The board also connects to several IGBT boards via six plug connectors. Five stab-on connectors (located behind the front faceplate,) are used to detect Phase A/B/C sensing signals and DC-link positive and negative signals. It is worth noting the IS200BPIBG1A has no LED indicators, fuses, or TP test points.
The IS200BPIBG1A has a serial 1024-bit memory chip to keep track of the board identification and revision information. The board also has over thirty other integrated circuits, including oscillating chips. It has four transistors, three transformers, and sixteen resistor network arrays. The majority of resistors used on this board are made of metal film material.
