Description

The IS200VGENH1B is a GE Mark VI printed circuit board component. The Mark VI is a gas and steam turbine management system that was released by GE as part of the ‘Speedtronic' line.GE began releasing these systems in the 1960s with the Mark I and continued for decades with different iterations through to the Mark VI and Mark VIe that were released in the ‘90s and the 2000s.The Mark VI includes an Operator Interface designed around a PC with a Windows operating system, preloaded with software designed to interact with the Mark VI hardware, like CIMPLICITY graphics. The IS200VGENH1B serves two roles within the Mark VI system.One, it acts as an interface for 1 phase CTs and 3 phase PTs.It also functions as a specialized control board for Early/Valve Actuation and Power/Load Unbalance on reheat steam turbines.The board has a narrow front faceplate that connects to the PCB via three screw connections. The faceplate has three LED indicators. TheIS200VGENH1B is built with two backplanes located side-by-side on the rear edge of the board.The board has several other connectors that primarily consist of parallel conductive traces. The board has multiple transistors.It has several capacitors, resistors, and diodes, as well as dozens of integrated circuits. Some of these circuits include programmable logic devices (XILINX XC95216) and field programmable gate arrays (XILINX XCS30,) as well as oscillating chips.The board is marked with the manufacturer's logo and with the code 6BA01. Components tend to have reference designators, but not all components are marked.
