Whereas the USB-2404-10 and USB-2404-60 modules measured voltage only (±10 V and ±60 V, respectively), the USB-2404-UI can be used to measure a variety of signal types, from such sensors as RTDs, thermocouples, load cells, and other powered sensors.
Each of the four channels has a detachable six-position spring terminal, which is individually configurable, so a different measurement type can be performed on each channel. All channels are measured simultaneously at up to 100 S/s per channel.
The device features built-in current and voltage excitation, which is protected from both overcurrent and overvoltage fault conditions. Each channel also has a built-in thermistor for cold-junction compensation (CJC) calculations when measuring thermocouples.
An analog prefilter removes noise that may be present in the signals prior to conversion. With 250 VAC channel-to-channel and channel-to-ground isolation, the USB-2404-UI protects the individual channels and connected computer and ensures a reliable data stream. The status of the device is indicated by an on-board LED.
Each channel has a detachable six-position spring terminal for field wiring connections. Additional connectors are available for purchase. A strain relief kit is also available to secure signal wires. The USB-2404-UI ships with a 2-meter USB cable and is powered by the +5 volt USB supply from your computer. No external power is required.
“The real excitement with the USB-2404-UI lies in its universal analog input feature,” observed Jim Stevens, Measurement Computing’s vice president of R&D, “Users can simultaneously acquire four channels of data, choosing from any of six measurement types. That makes a pretty nice package. And, as always, the price is right.”
The USB-2404-UI series 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; Universal Library™; and InstaCal™ installation, calibration, and test utility—powerful software solutions for programmers and nonprogrammers alike.
The USB-2404-UI operates under Microsoft Windows 2000/XP/Vista® (32-bit) operating systems.
