GE DS200FCGDH1A Gate Distribution and Status Board

Part Number DS200FCGDH1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark V Function Module Availability In StockDS200FCGDH1A is a Gate Distribution and Status Board manufactured and designed by General Electric and is part of the LS2100 Innovation Series used in Static Starter Control systems. An interface board for a 6-pulse phase-controlled, non-reversing bridge is called the Gate Distribution and Status Card (FCGD). Through the VME backplane, it transmits feedback and diagnostic data after receiving SCR firing data from the DS200DSPC (DSPC, the VME processor) chip. 

The FCGD receives a multiplexed cell status signal from each bridge leg and decodes and de-tributes the cell gating signals for each bridge leg. Additionally, it takes in bridge feedback signals, scales them, and then transmits the voltage, frequency, and current status data back to the DSPC board. GATE DISTRIBUTION AND STATUS BOARD FUNCTION: SYSTEM CLOCK: The FCGD features a system clock register that produces firing commands and timestamp feedback values. 

This 16-bit up-counter ends when it reaches the hexadecimal value 0FFFFH and resets to 0. SYSTEM RESET: During power-ups or hardware resets, the system reset signal sets all of the registers on the board to their starting settings. SYSTEM HEARTBEAT: An electronic component's heartbeat is a regular signal that it sends out to let other components know that it is still alive and well. This function is supported by the system heartbeat register on the FCGD. 

The board-level heartbeat starts to count at the same rate as the system clock when the VME host CPU writes to it for the first time, and a green board-front LED marked IMOK (I am alright) turns on. ANALOG & DIGITAL CONDITIONING: For analog voltage, current, and flux feedback, voltage-controlled oscillators are utilized. The VCOs are driven by the signals VA, VB, VC, VDC, IA, IC, FLUXBAR, and FLUXCBR (see Table 1). Additionally, six parallel Sigma-Delta converters that work with the VCOs are fed with the voltage and current signals.
