Description

DI-2108XL High Speed USB Data Acquisition and Data Logger System with Windaq software and 32GB USB flash drive. Features 8 differential analog 10V input channels, and stand-alone data recording to removable USB thumb drive.

DI-2108XL delivers premium analog performance at a surprisingly affordable price. The differential input configuration provides noise rejection, easily adapts to singleended signal sources, and is protected up to ±50 V dc or peak ac so that inevitable measurement mishaps will not harm the instrument. The front-end feeds a flexible 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. Rounding off the analog subsystem are anti-alias filters per channel with automatic selection of corner frequency at approximately one tenth of the sampling frequency.

DI-2108XL 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.

A USB drive is used to record data in stand-alone mode. Two file formats are supported, Excel compatible CSV file forma and WinDaq file. With Excel compatible CSV format, DI-2108XL can record 200 rows of data per second. With WinDaq file, sample rate of 160K is possible with industrial grade SCL microSD card.

Real Time Trigger Excel Link

The DI-2108XL comes with WinDaq ExcelLink. It provides real-time conection to Excel spreadsheet (32- or 64-bit) and can stream data to Excel spreadsheet at high speed. Four trigger methods are provided - two-point window trigger, one-point slope trigger with pre- and post-trigger data, manual single row and block trigger, and programmable event driven single-row trigger.

Even though Excel can store over 1,000,000 rows of data, it is still a small buffer for high speed data aquisition unless trigger modes are utilized so that only data of interests is captured. ExcelLink supports advanced math to construct trigger methods. Window trigger can capture signals inside or outside a range. Slope trigger with pre- and post- trigger can capture signals before and after a predefined trigger point. Event trigger can capture a single row of data at the moment trigger conditions are met. Derivative trigger to trigger on rate of change, such as a glitch. Manual trigger can capture signals at operator's key instruction.

With data directly streaming to Excel, powerful real time analysis and many charting options are available, such as grouping multiple channels in a single chart.

Frequently Asked Questions

Can I record 4-20mA sensor signals and if so, how do I do that?
4-20-mA process current signals can be measured with the DI-2108. See How to make 4-20mA current Loop Measurements for more information.

Does the device have internal memory (i.e. can I record in stand-alone mode)?
Though the DI-2108 does not have internal memory you can record data to a removable USB thumb drive (included with purchase). Configure the device with your PC then deploy in the field. An unlock code is required to store more than one channel to the USB thumb drive.

What kind of thumb drive can I use?
Almost any off-the shelf thumb drive can be used but could cause gaps in data. The thumb drives provided on our web site are tested and rated for speed. For higher speeds we recommend using the SLC micro SD card with a USB A microSD card reader available in Accessories.

Can I connect and measure data from a single-ended sensor?
Yes. Single-ended sensors can be connected and measured. The best practice is to connect the ground wire to the negative input of the channel.

Can I measure Thermocouple temperatures?
Thermcouple temperature measurements would not be accurate using the DI-2108 and should not be attempted. Thermocouple measurements are non-linear and require special programming to provide accurate readings.

Is software included with the device?
WinDaq Data Acquisition and Playback Software is included free.

Where do I download the software?
Download ExcelLink at https://dataq.com/support/downloads/WinDaq-Acquisition-Add-ons-Setup.exe.

Download WinDaq at https://www.dataq.com/support/downloads/DATAQ-Software-Suite-Web-Setup.exe.

Does the DI-2108 include a calibration certificate?
All new DI-2108 instruments ship with an NIST-traceable calibration certificate.

Can I get the DI-2108 re-calibrated?
Recalibration service is available and can be ordered online.

How often should I get the DI-2108 re-calibrated?
The DI-2108 should be re-calibrated annually.

Is my sensor compatible with this device?
Maybe. Sensors with an output within the range of ±10 Volts can be used with the DI-2108. See how fine a measurement you can make with your sensor using the ADC Resolution Calculator. If you have any questions about compatibility just send your sensor information to our sales team at sales@dataq.com.

Is the DI-2108 Isolated?
The DI-2108 is not an isolated instrument. The armored analog inputs can withstand up to ±50 V without damage.

Does the DI-2108 include digital or analog output channels?
The DI-2108 has seven bi-directional digital ports that can be programmed as an input or switch..

My sensor requires a power source, can the DI-2108 provide that power?
Yes. The DI-2108 can provide +5V power by connecting the appropriate wire to the +5V pin.
