Description
DI-4718B-U USB Data Logger and Data Acquisition System for applications that require signal conditioning. Install up to eight DI-8B isolated signal conditioning modules on the printed circuit board using the removable front panel. Each DI-8B module protects, filters, amplifies, and isolates an input signal, providing an advanced signal conditioning solution for nearly any industrial measurement.
Model DI-4718B features 12- to 16-bit analog-to-digital resolution as a function of sample rate. Lower sampling rates deliver higher resolution readings. The maximum analog sampling throughput rate of the DI-4718B analog subsystem is 160 kHz, providing 12 bits of resolution. Resolution varies with respect to sample rate. Add up to 128 analog channels with ChannelStretch™ channel expansion, which is supported in all USB and Ethernet versions. Synchronize any USB DI-4718Bs, DI-4108s, DI-4208s, and/or DI-1120s to one PC or synchonize multiple DI-4718B Ethernet units. Acquire from as many as 128 analog and 112 digital channels at combined total throughput rates over 480 kHz.
Use a USB drive to record data in stand-alone mode. The DI-4718B can record to a USB thumb drive continuously using a circular buffer with pre-defined trigger conditions or a record-until-full approach supporting remote start/stop. A push button allows manual start/stop control over the recording process. With a flash memory card incorporating SLC technology, throughput rates up to 160 kHz can be achieved. That rate drops to 50 kHz when using pSLC card, and 20 kHz using a flash memory card incorporating MLC. The included WinDaq data acquisition software makes configuring the DI-4718B for stand-alone operation quick and intuitive. Use WinDaq to set up channels and create a reference file. That reference file can then be copied to the USB drive and used for quick setup.
