GE MRP643486 IS200VSVOH1BDC — VME Servo Control Card

Description

• Channels: 4 independent servo outputs, current-mode drive
• Output Range: 0 – 200 mA per channel, short-circuit protected
• Input Types:
  – Digital speed feedback (magnetic pickup or encoder)
  – Analog position feedback (LVDT / RVDT)
• Processor: 32-bit DSP, 40 MHz
• Resolution: 16-bit current command, 12-bit feedback
• Loop Update: 2 kHz per channel
• Communications:
  – VME64 master/slave interface
  – RS-232 service port for configuration
  – Redundant Ethernet (optional daughter card)
• Power: +5 V 3 A, +24 V 1 A from VME backplane
• Isolation: 1 kV channel-to-channel, 2.5 kV channel-to-ground
• Operating Temperature: –40 °C to +70 °C
• Dimensions: 233 mm × 160 mm × 20 mm (6U single-slot)
• Weight: 0.6 kg

• Redundant speed sensor support: accepts both active and passive pickups
• Configurable servo coils: 2-coil or 3-coil servo valves selectable via jumper
• Auto-calibration: software trims offset and gain for each channel
• Real-time diagnostics: open-circuit, short-circuit, over-range, and temperature alarms
• Hot-swap support: replace module without shutting down the VME rack
• Watchdog timer: forces outputs to safe state on CPU fault

• Gas turbine fuel and IGV servo loops
• Steam turbine governor and intercept valve control
• Compressor anti-surge valve positioning
• Industrial test rigs requiring high-bandwidth hydraulic actuation
