Description

The IS200VTCCH1B is a GE board component made for the Mark VI system. The Mark VI is from GE's popular Speedtronic line that has over thirty years of research and development behind its gas and steam turbine management properties.The Mark VI is the third of these systems to include triple redundant backups on all critical controls. In the Mark VI system, this primarily occurs within the Central Control Module.This control module connects to a human-machine interface (HMI) that allows access to turbine data. The IS200VTCCH1B has a front faceplate with three LEDs mounted into its surface. These LEDs are labeled run/fail/status and are green, red, and orange in color. The faceplate attaches to the PCB using screw connections. The IS200VTCCH1B functions as a Thermocouple Input.It accepts up to twenty-four thermocouple inputs using terminal boards (TBTC or DTTC.)This board supports E, J, K, S, and T types of thermocouples and mV inputs with a span of -8mV to +45mV. The IS200VTCCH1B has six board connectors (P1 through P6.) This includes two backplanes (P1 and P2,) and four connectors created by conductive traces and dots.The board is component dense and includes hundreds each of resistors and capacitors. The board also has inductor coils/beads (L1 through L19,) TP test points, diodes, and integrated circuits.Circuits include Xilinx Spartan XCS30 field programmable gate arrays, Dual port SRAM, CMOS Static RAM, and digital signal processors. The board is marked with codes like 94V0, E99006, and Type 6.More information is available through manuals, data sheets, or the MKVI Turbine Control System Guide (GEH-6421.)
