8 Channel High Speed Voltage Input USB Data Acquisition Module
8-Channel High Speed Voltage Input USB Data Acquisition Modules
- 4 Differential/8 Single-Ended Analog Voltage Inputs
- 13-Bit Resolution
- Up to 4 Analog Outputs
- 16 Digital I/O
The OM-USB-1208HS, OM-USB-1208HS-2AO and OM-USB-1208HS-4AO are USB 2.0 full-speed voltage input data acquisition modules (fully compatible with both USB 1.1 and USB 2.0 ports). These are stand-alone plug-and-play modules which draw power from the USB cable– no external power supply is required. All configurable options (including individual channel ranges) are software programmable, and the modules are fully software calibrated. All three OM-USB-1208HS modules provide 13-bit resolution, and 4 differential or 8 single-ended analog inputs. These modules support software programmable ranges from ±5 to ±20V in a differential configuration, and ±2.5 to ±10V, and 0 to 10V in a single-ended configuration. In software-paced mode, these modules can sample at a maximum of 4 kS/s. In hardwarepaced mode, they can sample at a maximum of 1 MS/s. The OM-USB-1208HS-2AO provides two 12-bit analog outputs, and the USB-1208HS-4AO provides four 12-bit analog outputs.
Both modules offer an output range of ±10V. Analog outputs update at a maximum rate of 5 kS/s in softwarepaced mode; in hardware-paced mode, each analog output updates at a maximum rate of 1 MS/s. On these modules, 16 digital I/O can be programmed on each individual bit as either inputs or outputs. Each module supports two 32-bit TTL-level counters that accept frequency inputs of up to 20 MHz. The packaging for the OM-USB-1208HS, OM-USB-1208HS-2AO and OM-USB-1208HS-4AO ensures ease of use in a variety of applications. The modules can easily be DIN-rail mounted for rack applications.
The OM-USB-1208HS, OM-USB-1208HS-2AO and OM-USB-1208HS-4AO 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.
The OM-USB-1208HS, OM-USB-1208HS-2AO and OM-USB-1208HS-4AO data acquisition modules are supplied with TracerDAQ software which is a collection of four virtual instrument applications used to graphically display and store input data and generate output signals:
• Strip Chart—Log and graph values acquire from analog inputs,
digital inputs, temperature inputs and counter inputs
• Oscilloscope—Display values acquired from analog inputs
• Function Generator—Generate waveforms for analog outputs
• Rate Generator—Generate waveforms for counter outputs
TracerDAQ PRO is an enhanced version of TracerDAQ. A comparison
of some of the feature included in TracerDAQ vs TracerDQ PRO is shown on the PDF.
