USB-based 24-bit, isolated, high-channel-count DAQ module. Measurement Computing's USB-2416-4AO is a multifunction measurement and control board designed for the USB bus. It is a multiplexed 24-bit measurement system that provides up to 16 differential and up to 32 single-ended analog inputs with a 1 kS/s aggregate throughput. It offers nine software-selectable analog input ranges (±20V, ±10V, ±5V, ±2.5V, ±1.25V, ±0.625V, ±0.312V, ±0.156V, ±0.078V). The analog inputs can be configured as thermocouple inputs (up to 16 differential). In thermocouple mode, the USB-2416-4AO includes built-in cold-junction compensation and open thermocouple detection. In addition to the analog inputs, the USB-2416-4AO includes eight lines of digital I/O and two 32-bit counters, plus four 16-bit analog outputs with an update rate of 1000 S/s, and an output range of ±10V. The USB-2416-4AO provides 500 VDC isolation between the field wiring and the USB interface. The PS-5V2AEPS 10-W regulated power supply (included), provides the 5 VDC, 2A power to the USB-2416-4AO. An optional expansion module (AI-EXP32) doubles the analog input channels to 32DI/64SE, and adds 16 digital I/O lines.
