Introducing the USB-2408 Series
Overview: USB-2408 Series features
The USB-2408, USB-2408-2AO includes the following devices:
 USB-2408
 USB-2408-2AO
These devices are USB 2.0 full-speed devices that are supported under the following operating systems:
 Microsoft Windows® 8/7/Vista®/XP (32-bit or 64-bit)
 Macintosh (32-bit or 64-bit)
 Linux (32-bit or 64-bit)
Each USB-2408 Series device provides the following features:
 16 single-ended (SE) or eight differential (DIFF) 24-bit analog inputs with sampling rates up to 1 kS/s.
Each channel is software-configurable as SE or DIFF. For each DIFF channel pair, you lose one SE
channel.
 Analog input ranges of ±10 V, ±5 V, ±2.5 V, ±1.25 V, ±0.625 V, ±0.312 V, ±0.156 V, and ±0.078 V.
 Up to eight analog inputs can be configured as DIFF thermocouple (TC) inputs, which include built-in
cold-junction compensation and open TC detection.
 Computer protection provided through a minimum of 500 VDC input isolation between field wiring and the
USB interface.
 Eight lines of digital I/O and two 32-bit counters.
 Screw terminals for field wiring connections
The USB-2408-2AO also provides two 16-bit analog output channels. You can pace a single channel at rates of
up to 1 kS/s. You can pace both channels simultaneously at rates of up to 500 S/s.
