  • A 12-bit DAC is used for the analog outputs, providing smooth and accurate signal generation.
• Input Types: Supports both single-ended (SE) and differential (Diff) input configurations, allowing for flexible connection to various sensors and signal sources.
• Voltage Ranges:
  • Inputs: Single-pole (0 to +10 V, 0 to +5 V) or bipolar (±2.5 V, ±5 V, ±10 V), catering to a wide range of signal levels.
  • Outputs: Each output channel can provide or sink 10 mA of current at voltages up to ±10 V, making it suitable for driving various loads.
• A/D Conversion Time: 15 microseconds, ensuring fast and responsive data acquisition.
• A/D Acquisition Time: 10 microseconds, minimizing the delay between signal sampling and conversion.
• A/D Throughput: Up to 40 kHz (maximum), allowing for high-speed data processing in real-time applications.
• Common-Mode Range: ±11 V (maximum), providing excellent common-mode rejection for noisy environments.
• Common-Mode Rejection: 82 dB, ensuring accurate signal measurement even in the presence of common-mode noise.
• Operating Modes:
  • Auto-Scan Mode: Continuously scans all channels upon power-up or program selection, storing digitized data in dedicated dual-port registers for easy retrieval.
  • 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, ensuring reliable operation and facilitating troubleshooting.
• Output Protection: Features output short-circuit protection and is designed to be fail-safe during power-off conditions, enhancing system durability.
• Address Selection: The physical address of the board can be selected using onboard jumpers, with VMEbus address lines A06 to A15 decoded to select the board.
• Connectivity: Analog signals are accessible via the P2 backplane connector, providing a convenient and reliable connection interface.
• Power Supply: The board can be equipped with a replaceable power supply board, facilitating maintenance and upgrades.
