USB data-acquisition line grows
Staff -- Test & Measurement World, 9/1/2005
National Instruments' line of USB data-acquisition modules includes eight new models, all of which run at USB 2.0 speeds. The line includes a 24-bit, four-channel thermocouple model ($395); a 24-bit, four-channel, 50-ksample/s model ($1295); and a 16-bit, 100-ksample/s, four-channel, simultaneous-sampling model ($475). Two 12-bit, eight-channel analog-input modules are also available: one samples at 500 ksamples/s ($595), while the other can handle ±60 V at 800 ksamples/s ($745). Digital I/O modules include eight-channel input and output modules and a relay module ($295 each).
All models feature 250 Vrms channel-to-ground isolation. Analog-input units include software for logging data or controlling digital I/O. Connection options include screw-terminal connectors for temporary hookups or 25-pin D connectors for more permanent connections.
