The USB data acquisition module of the OMB-DAQ-2408 Series are designed for highly-accurate voltage or temperature measurements. Each device features up to 16 single ended (SE)/8 differential (DIFF)
analog inputs. Each device includes 8 digital I/O and two counter inputs. The OMB-DAQ-2408-2AO
also features two analog outputs. Each device in the series offers 24-bit resolution for ultra-accurate voltage or thermocouple measurements.

Analog Input
Each device includes 16 SE/8 DIFF analog inputs which you can configure for voltage or thermocouple input on a per-channel basis. Eight software-selectable voltage input ranges are provided. You can configure these ranges on a per-channel basis from ±10V to ±0.078V. When measuring thermocouples, configure analog inputs in DIFF mode. All devices also include open thermocouple detection to identify improperly working thermocouples.

Sample Rate
OMB-DAQ-2408 modules can sample analog input channels at up to 1 kS/s.

Digital I/O
Eight digital I/O channels are included with each OMB-DAQ-2408
and you can read from or write to each individual bit.

Counters
Two 32-bit counters are included with OMB-DAQ-2408 modules. The TTL level inputs
are capable of read/write rates of up to 500 Hz and an input frequency of up to 1 MHz.

Analog Output
(OMB-DAQ-2408-2AO Only)
The OMB-DAQ-2408-2AO includes two 16-bit analog outputs. Each output has a ±10V range.
Both outputs can be updated at a rate of up to 500 S/s per channel; one output can be updated
at a rate of 1 kS/s.

Software
The OMB-DAQ-2408 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 VIs and example programs compatible with 32-bit and 64-bit LabVIEW v8.5 through 2012) and InstaCalTM 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.
