National Instruments says it has introduced the industry's first 80-channel USB DAQ devices, together with the BNC USB M-series devices and a USB-9237 C-series module. The 80-channel USB M-series devices are said to deliver the highest channel-count among USB multifunction DAQ devices; the BNC USB M-series devices provide direct BNC connectivity; and the USB C-series modules offer less expensive and more portable hardware, according to NI.

Using the 80-channel USB M-series devices, engineers can collect more data with less equipment because the devices provide high-channel-count application solutions in a single device. The NI USB-6225 and USB-6255 offer 80 channels for analogue inputs and up to 1.25MSps (750KSps aggregate) sampling rates per channel. The devices feature NI signal streaming and provide up to 48 digital I/O lines and two counter/timers.

The NI USB-6221, USB-6229, USB-6251 and USB-6259 BNC USB M-series devices include the standard M-series features along with direct BNC connectivity that provides up to 16 differential analogue inputs, four analogue outputs, eight digital I/O BNC connectors and up to 60 screw terminals. The BNC devices offer up to 1.25MSps (750KSps aggregate) sampling rates per channel, support NI signal streaming technology, provide up to 48 digital I/O lines and feature two counter/timers.

The USB-9237, based on the NI C-series platform, offers high-speed in a compact form factor for low-channel-count applications including strain, load, pressure and other bridge-based measurements. The bus-powered module removes the need for an external power supply and offers NIST-traceable calibration and quarter-, half- and full-bridge completion. Other features include 24bit resolution, direct connectivity, 50KSps simultaneously sampled analog inputs, up to 10V internal excitation, and transducer electronic data sheet (TEDS) smart sensor compatibility.

Pricing for the 80-channel USB M-series devices starts at Rs.64,676.82 ($1,599); for the BNC USB M-series devices it's from Rs.64,676.82 ($1,599); and for the NI USB-9237 it starts at Rs.52,542.33 ($1,299).
