Description

DI-2108-P High Speed USB Data Acquisition System with Windaq software. Features 8 differential analog input channels, 16-bit measurement resolution, and a full scale ranges of ±2.5, ±5, ±10, 0-5, 0-10 Volts.

Model DI-2108-P delivers premium analog performance at a surprisingly affordable price. Eight analog input channels provide differential measurement flexibility and programmable ±2.5, 5, 10 V bipolar and 0-5 and 0-10 V unipolar ranges per channel. The differential input configuration provides noise rejection, easily adapts to single-ended signal sources, and is protected up to ±300 V dc or peak ac so that inevitable measurement mishaps will not harm the instrument. Bipolar ranges measure signals above and below zero, while resolu-tion is effectively doubled on unipolar ranges. The front end feeds a fixed resolution, 16-bit ADC. The maximum sampling throughput rate of the DI-2108-P is 160 kHz.

The DI-2108-P provides 7 digital ports, each configurable as an input or a switch. Input protection is provided to 25 V. When activated as inputs two ports allow dual functionality as discrete inputs, or programmed as a counter or rate input. The rate input features a 50 kHz maximum measurement allocated over twelve programmable measurement ranges (10 Hz to 50 kHz full scale.) The counter input provides 16-bit resolution and a terminal count value of 65,535. The discrete, counter, and rate inputs are members of the same internal scan list used by the analog input channels. This means that all enabled elements are acquired synchronously, which allows meaningful comparisons between analog and digital channels. For example, the rate input measuring engine speed allows rpm data to be acquired in lock-step with analog data. Configured as a switch a digital port can be used to control external loads up to 25 V @ 100 mA, and the switch can be controlled asynchronously without interfering with the scanning process.
