USB-2416-4AO Temperature/Voltage DAQ Device

Digilent's measurement computing USB-2416-4AO is ideal for higher channel count applications measuring voltage or thermocouples. Features include expandable analog and digital I/O, along with counter functions. The USB-2416-4AO features 32 SE/16 DIFF, 16-bit analog inputs for measuring voltage or thermocouples measurements (thermocouples are measured in DIFF mode), 1 kS/s sample rate, four analog outputs, eight digital I/O, and two counter inputs. It provides four 16-bit analog outputs with a ±10 V output range, and the analog outputs can be updated at a maximum rate of 1 kS/s (system dependent).

The USB-2416-4AO provides eight digital I/O lines with read/write rates of 500 port or single-bit reads per second. Each DIO channel is an open drain. Digital outputs can sink up to 150 mA for direct drive applications. The maximum sink current is 150 mA per eight-channel bank, or 18 mA (maximum) per channel if all eight channels are used. The device has two 32-bit event counters that accept frequency inputs up to 1 MHz. The internal counter increments when the TTL levels transition from low to high.

The AI-EXP32 expansion device provides an additional 32 SE/16 DIFF analog inputs and 16 DIO lines. It supports all analog/thermocouple input and digital I/O features of the USB-2416 series devices to which it is connected. The USB-2416 series docks directly to the AI-EXP32 with an expansion connector on each device. No additional cable is required. The AI-EXP32 receives power from the connected USB-2416 series device. The USB-2416-4AO is externally powered by an included 5 V power supply.

Software support includes DAQami, an out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for the most popular applications and programming languages, including Visual C++®, Visual C#®, Visual Basic® .NET, DASYLab®, LabVIEW™, Linux®, and Python™.
