### 4. Functionality

The EXP‑8A module functions as a precision voltage‑to‑current converter. Each of the eight channels receives a ±10 V analog voltage signal from the corresponding DAC output of the PCI‑6208V main card. The XTR110 transducer on each channel converts this voltage into a proportional current output according to the selected range. The conversion relationship is linear and software‑controlled through ADLINK’s driver library.

Operating Principle:

- Input voltage (0–10 V) corresponds to a defined current range (e.g., 0–20 mA).
- The transducer maintains high linearity and low temperature drift.
- Output current is sourced through the external load connected between the channel output and analog ground (AGND).

Use Cases and Applications:

- Industrial process control loops (4–20 mA transmitters).
- Servo and actuator control systems.
- Pressure, temperature, and flow transmitter simulation.
- Automated Test Equipment (ATE) requiring current sourcing.
- Function generation and calibration systems.

Compatibility:

- Designed for integration with ADLINK PCI‑6208V analog output card.
- Forms the PCI‑6208A configuration when installed.
- Compatible with PCI‑6216V and other NuDAQ series accessories.
- Supported by ADLINK’s DAQPilot, DAQMaster, and legacy PCIS‑DASK software libraries.
