GE VMIVME-4514

• Digital-to-Analog Converter (DAC):
  • Each of the 16 analog output channels has its own sample-and-hold (S&H) output.
  • A 12-bit DAC is used for the analog outputs.
• Input Types:
  • Supports both single-ended (SE) and differential (Diff) input configurations.
• Voltage Ranges:
  • Inputs: Single-pole (0 to +10 V, 0 to +5 V) or bipolar (±2.5 V, ±5 V, ±10 V).
  • Outputs: Each output channel can provide or sink 10 mA of current at voltages up to ±10 V.
• A/D Conversion Time: 15 microseconds.
• A/D Acquisition Time: 10 microseconds.
• A/D Throughput: Up to 40 kHz (maximum).
• Monotonicity: Maintains monotonicity across the full temperature range.
• Common-Mode Range: ±11 V (maximum).
• Common-Mode Rejection: 82 dB.
• Operating Modes:
  • Auto-Scan Mode: Continuously scans all channels upon power-up or program selection, storing digitized data in dedicated dual-port registers.
  • Random Polling Mode: Requires the control program to initiate each conversion, with conversion completion determined by polling the conversion end status bit.
  • Scan Polling Mode: Performs a single scan of all channels, with scan completion determined by polling the scan end control bit.
• Built-in Test (BIT):
  • Supports 100% testing of active components on the board.
  • Enables offline testing by disconnecting the analog outputs from the I/O connectors.
• Output Protection:
  • Features output short-circuit protection.
  • Designed to be fail-safe during power-off conditions.
• Address Selection:
  • The physical address of the board can be selected using onboard jumpers.
  • VMEbus address lines A06 to A15 are decoded to select the board.
• Connectivity:
  • Analog signals are accessible via the P2 backplane connector.
• Power Supply:
  • The board can be equipped with a replaceable power supply board.
