USB2816 data acquisition card is a data acquisition card based on USB bus, which can be directly connected to the USB interface of computer, and can be used in various fields of laboratory, product quality testing center, data acquisition, waveform analysis and processing system. It can also be used to monitor industrial production processes.
The USB2816 is a USB‑based data acquisition card that provides up to 16 single‑ended (or 8 differential) analog inputs, 4 analog outputs, digital I/O and a programmable 8254 timer/counter. The manual describes the card’s hardware layout, signal connections, and the software setup required for operation.
Key sections include functional overview, component layout, AD/DA conversion details, timer/counter usage, installation checklist, calibration procedures, and warranty information. The document is written in Chinese and targets engineers integrating the card into measurement systems.
| AD maximum sampling rate | 230 kHz |
|---|---|
| Analog input channels | 16 single‑ended / 8 differential |
| AD input voltage range | ±10 V (0‑10 V, ±5 V, ±2.5 V options) |
| DA maximum output rate | 100 kHz |
| Analog output channels | 4 |
| Operating temperature range | 0 °C – +50 °C |
| Storage temperature range | -20 °C – +70 °C |
The AD converter can sample up to 230 kHz.
It provides 16 single‑ended channels or 8 differential channels.
The device operates from 0 °C to +50 °C.
Connect the input channel to a known voltage (e.g., 10 V), run the USB2816 software, select single‑channel mode, and adjust until the measured value matches the reference.
