The Digilent MCC USB-2416-4AO Series offers exceptional performance and accuracy for voltage and temperature measurements. Designed for the USB bus, the device provides up to 32 analog input channels with 24-bit resolution, 8 digital I/O and two counter inputs. The USB-2416-4AO also features four analog outputs. The USB-2416-4AO is powered by an external 5V, 2A regulated power supply that is shipped with the device.

Connect to the AI-EXP32 expansion device (sold separately) for an additional 32 channels of analog input and 16 digital I/O lines.

Analog Input

The USB-2416-4AO provides 32 SE/16 DIFF analog inputs, expandable to 64 SE/32 DIFF. Software-selectable voltage input ranges are configurable per-channel. The device can sample analog input channels at up to 1 kS/s. Open thermocouple detection is automatically enabled for thermocouple measurements.

Analog Output

The USB-2416-4AO provides four 16-bit analog outputs with a ±10 V output range. The analog outputs can be updated at a maximum rate of 1 kS/s (system dependent).

Digital I/O

USB-2416 Series devices provide 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 if all eight channels are used, 18 mA (maximum) per channel.

Counter Input

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.

Calibration

The USB-2416 Series is factory-calibrated using a NIST-traceable calibration process. Specifications are guaranteed for one year. The USB-2416 Series also supports field calibration for users to calibrate the device locally with the InstaCal utility.
