Key Features

1. 16‑Bit High‑Precision Conversion: Delivers 16‑bit resolution with no missing codes and ±0.003% full‑scale accuracy, ensuring precise measurement of low‑level analog signals in critical applications.
2. 64‑Channel High‑Density Input: Supports 64 differential or single‑ended inputs, reducing system complexity and cost by consolidating multiple signal sources into a single VMEbus slot.
3. Software‑Programmable Ranges & Gains: Offers ±2 V, ±5 V, ±10 V input ranges and 1×–8× gain settings, enabling flexibility to interface with diverse sensors (thermocouples, RTDs, strain gauges, transmitters).
4. Autonomous Scanning & Timing: On‑board 8254 timers and sequencers enable self‑paced channel scanning (381 Hz to 100 kHz) without host processor intervention, ensuring deterministic data acquisition.
5. Dual‑Ported Data Memory: 32 KB dual‑ported RAM allows simultaneous access by the ADC and VMEbus host, minimizing data latency and enabling high‑speed data streaming.
6. Multiple Operating Modes: Supports auto‑scan, data burst, and external synchronization modes, accommodating continuous monitoring, batch sampling, and event‑triggered acquisition.
7. Robust Industrial Design: Constructed for harsh environments with 0°C to +65°C operating temperature, vibration‑resistant components, and VMEbus compliance for reliable long‑term operation.
8. Flexible VMEbus Interface: Supports A16/A24/A32 addressing, D16/D32 data transfers, and programmable interrupts (levels 1–7), ensuring seamless integration with legacy and modern VMEbus systems.
9. Signal Conditioning Compatibility: Interfaces directly with GE/VMIC signal conditioning boards for thermocouple, RTD, and strain gauge inputs, simplifying sensor integration.
10. ‑020000 Standard Configuration: Optimized for general‑purpose use with 96‑pin non‑latching connectors, no input filters, and default firmware, reducing setup time and ensuring compatibility with most standard systems.
