### 2. Key Features

- Bus Isolation via Optocouplers:
Complete electrical isolation between the PC and external I/O circuits ensures high noise immunity and protection against ground loops.

- Flexible Analog Input Configuration:
Supports 16 single‑ended or 8 differential analog input channels, selectable via onboard jumpers. Input ranges include both bipolar (±1.25 V, ±2.5 V, ±5 V, ±10 V) and unipolar (0–1.25 V, 0–2.5 V, 0–5 V, 0–10 V) voltage ranges, as well as 4–20 mA current input.

- High‑Speed 12‑bit A/D Conversion:
Conversion speed up to 20 µs per channel (50 kS/s aggregate), suitable for medium‑speed data acquisition and control applications.

- Large Onboard Buffer Memory:
256 k‑word buffer configurable as FIFO or ring memory, enabling continuous or cyclic sampling independent of host CPU load.

- Advanced Sampling Control:
Sampling can be triggered or stopped by software, external digital signals, or analog level comparison. Internal or external sampling clocks are selectable.

- Optically Isolated Digital I/O:
Four optocoupler‑isolated digital inputs and four open‑collector digital outputs (sink type), each with ≤ 1 ms response time, allow safe interfacing with external control devices.

- Software‑Based Calibration:
Full calibration of analog input channels can be performed via software, with user‑defined adjustment data stored for environmental compensation.

- Comprehensive Software Support:
Includes Windows and Linux driver libraries (API‑PAC(W32)), sample programs for Visual Basic, Visual C++, C#, Delphi, and gcc, and LabVIEW VI‑DAQ support.

- Optional Accessories and Expansion:
Wide range of optional cables, termination panels, and signal conditioning modules (e.g., low‑pass filters, isolation amplifiers, BNC panels).
