產品描述

This product has been discontinued.

The new OM-USB-2404 Series are high-speed USB data acquisition modules featuring four 24-bit simultaneous analog voltage inputs with a sampling rate of 50 kS/s per channel, and a ±10V (OM-USB-2404-10) or ±60V (OM-USB-2404-60) input range. These modules are fully compatible with both USB 1.1 and USB 2.0 ports. An anti-alias filter removes noise that may be present in the signals prior to conversion.

Full 250 Vrms channel-to-channel and channel-to-ground isolation protects the module and computer from ground spikes, and ensures a reliable data stream. An on-board LED indicates the status of the device. Field connections are made to four 2-pole, detachable screw terminals. The USB 2.0 high-speed driver transfers data at rates up to 480 Mbps. Power for the OM-USB-2404 Series comes from the 5V USB supply from your computer. No external power is required.

Software The OM-USB-2404 Series modules ship with an impressive array of software, including the new TracerDAQ?, a full-featured, out-of-the-box data logging, viewing, and analysis application. Driver support and detailed example programs are included for Universal Library programming libraries for Microsoft? Visual Studio? programming languages, and other languages, including DASYLab?, and ULx for NI LabVIEW? (comprehensive library of Vls and example programs compatible with 32-bit and 64-bit LabVIEW v8.5 through 2013) and InstaCal? installation, calibration and test utility-powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows? XP (32-bit only) and VISTA/7/8 (32-bit and 64-bit) operating systems.
