GE DS200FCGDH1B

Description

• Operating Temperature: −30 °C to +65 °C
• Logic Supply: 5 V DC (board electronics), 24 V DC (isolated I/O)
• Form Factor: 9.2 × 6.3 in (233 × 160 mm), single-slot VME slave
• Weight: 0.45 kg
• Connectors: VME P1/P2 backplane, 20-pin ribbon (NATO feedback), six fiber-optic transmitters (SCR firing), status LEDs

• Receives multiplexed cell-status signals from each bridge leg and decodes them into individual SCR gate pulses
• Generates and distributes high-current gate pulses via fiber-optic links to six SCR cells
• Scales bridge feedback (voltage, current, frequency) and routes digitised values to the DSPC over the VME backplane
• Integrates 16-bit system clock register for precise firing command timing and feedback timestamps
• System heartbeat register and “IMOK” green LED provide visual confirmation of board health
• On-board sigma-delta converters and VCOs condition analog feedback signals for high-resolution measurement
• Hardware reset circuit initialises all registers at power-up or after a watchdog timeout

• Large AC motor drives and load-commutated inverters (LCI) in power plants, steel mills, petrochemical facilities
• Synchronous motor starting systems, pumped-storage hydro units, and gas-turbine static starting systems
• Excitation control for generators in utilities and industrial co-generation plants
• Retrofit spare for legacy GE Mark V drive frames running in continuous process industries

• Mounts on standard Mark V/VI card cage; secured by top/bottom extraction levers
• Fiber-optic cables must maintain < 2 dB loss; bend radius ≥ 30 mm
• NATO feedback board jumpers set input scaling to match dc-link voltage level
• Firmware updates delivered via Mark VI Toolbox ST file; no on-board EPROM replacement required
• LED diagnostics: IMOK (heartbeat), GATE 1–6 (firing), FLT (fault)

• Single part number: DS200FCGDH1B
• Supplied with factory calibration sheet and Mark V control manual GEI-100221
• Origin: USA, HS Code 85389091
• Lead time: stock to 4 weeks depending on region
