Low-Cost 16-Channel DAQ Module Displays Flexibility

The DI-710 Data-Acquisition (DAQ) Module can be used as a standalone or a wire-connected product, bringing high performance at low cost. Crafted by Dataq Instruments, this 16-channel, 14-bit unit sports 512 Mbytes of memory on a removable module. It features a built-in channel gain-scan list as well as USB and Ethernet interfaces. Pricing starts at $399.

The standalone versions, which contain a removable multimedia card memory module, can be used with or without a PC connection. The tethered versions connect directly to the PC via USB or Ethernet ports.

The module boasts gain factors of 1, 2, 4, and 8 (H version) and 1, 10, 100, and 1000 (L version), along with eight digital I/O lines. Each of the 16 analog input channels is configurable for gain as well as for single-sided (16 channels) or differential (eight channels) operation. It sports a real-time clock and an 8-bit bidirectional I/O port as well. PC-tethered versions can stream data at 4800 samples/s, while standalone units store data at 7200 samples/s.

The DI-710 modules have removable 16-position screw-terminal access connectors. They come in a small enclosure comprising an aluminum base and end plates and an all-steel wraparound. The package measures 5.438 in. deep by 4.125 in. wide by 1.5 in. high. Input power ranges from 9 to 36 V dc, allowing for battery operation in remote or portable applications. An ac adapter is included as well.
