Beskrivelse
The OM-DAQ-USB-2401 is a USB
2.0 full speed thermocouple/voltage
input data acquisition module (fully
compatible with both USB 1.1 and
USB 2.0 ports). This stand-alone
module draws power from the host PC's USB
port to operate. An external power
supply is also included, to allow use with non-powered USB hubs. All
configurable options (including
individual channel input type and
range) are software programmable.
The OM-DAQ-USB-2401 is user programmable for thermocouple types J/K/T/E/R/S/B/N and voltage input ranges from ±30 mV to ±10V full scale.
The compact, modular
packaging ensures ease of use in a variety of applications. Units
can be DIN rail or wall mounted with
the included hardware and also have rubber feet for bench-top use. All analogue input channels can be measured sequentially at about 1 ms per channel. A total of 1000 samples per second can be taken, divided across all active channels.*

Omega's DAQ Central software for real-time display and data logging is included
DAQ Central software allows charting, data logging, file storage and virtual instrument viewing (digital meters, dial gauges, bar graphs) of data in real time. No programming is required - simply point, click, and drag desired display options to create a virtual display screen. Additionally, for those users who would like to design and develop their own custom applications, the software suite includes a .NET driver for C#, Visual Basic and Visual C++. |
