USB Data Acquisition and Data Logger DI-4108-U
DATAQ DI-4108 High Speed USB Data Acquisition System with Windaq software. Features 8 differential analog input channels (Unlock Code required to record more than 4 total channels to WinDaq), 12 to 16-bit measurement resolution, full scale ranges of ±200, ±500 mV, ±1, ±2, ±5, ±10 V full scale, and stand-alone data recording to removable USB thumb drive.
Eight analog input channels provide differential measurement flexibility and programmable ranges per channel of ±200, ±500 mV, ±1, ±2, ±5, ±10 V full scale. The differential input configuration provides noise rejection, easily adapts to single-ended signal sources, and is protected to 120 Vrms so that inevitable measurement mishaps will not harm the instrument. The front end feeds a variable resolution analog-to-digital converter that ranges from 12 to 16 bits as a function of sampling rate. Lower sampling rates deliver higher resolution readings. The maximum analog sampling throughput rate of the DI-4108 analog subsystem is 160 kHz, providing 12 bits of resolution. Below 10 kHz the instrument delivers 16-bit resolution with a single enabled analog channel. Below 2 kHz per analog channel the DI-4108 provides 16-resolution with five or more enabled analog channels.
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 can be programmed as a counter or rate input respectively. 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. Configured as a switch a digital port can be used to control external loads up to 25 V @ 100 mA.
