Description

The IS200VCRCH1A is a board component for the Mark VI created by GE.The Mark VI is part of the Speedtronic line of gas/steam turbine management that has been developed by General Electric over several decades. The IS200VCRCH1A functions as a Discrete Input/Output board.This board controls 24 relay outputs and accepts 48 discrete inputs from four terminal boards. The board mounts into the VME I/O rack, which has two sets of plugs (J3/J4) for cabling to terminal boards (TBCI and TRLY.)The IS200VCRCH1A is a narrow, single-slot version of a VCCC board. The IS200VCRCH1A is built with a front faceplate that includes three LED indicators. These LEDs include a green RUN” indicator, a red FAIL” indicator, and an orange Status” indicator.The board also has two cable connectors mounted into the faceplate (J33/J44.) The faceplate includes the manufacturer's logo and the board number.The board has several other connectors including two backplane connectors (P1/P2,) as well as three connectors (P4/P5/P6) that are made up of conductive dots. The IS200VCRCH1A has over thirty transistors on its surface.The board also has resistors, capacitors and diodes of various materials.The board uses inductor beads, test points, and many integrated circuits. Circuits include field programmable gate arrays like Xilinx Spartan XCS30 and Dual Port SRAM (IDT 7024S35JU0738P.)The board is component-dense. While most components carry designators, not all are marked due to space limitations. More information on the board specifications may be found within the MKVI Turbine Control System Guide.
