8/16 Channels USB Thermocouple and Voltage Input Module

The OM-DAQ-USB-2401 is a portable USB thermocouple/voltage input data acquisition module that can be used with either desktop or laptop PCs. This stand-alone module draws power from the USB port to operate and has 500V isolation to PC. An external power supply (optional) can be used. 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 or easily operated on a bench.

Software Configurable Channels
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.

Resolution and Speed
Even with it's high 24-bit resolution, all analog 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.*

A free Windows Software Suite that includes the DAQ Central menu driven Windows software is available for download from OMEGA. DAQ Central allows charting, data logging, file storage and virtual instrument viewing (digital meters, dial meters, 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 application program, the software suite includes a .NET driver for C#, Visual Basic and Visual C++.

If you are interested in temperature calibration, also select the appropriate temperature probes for the required number of channels.
