Measurement Computing adds “universal input” module to its USB-2404 line

May 2009: Adept Scientific (Letchworth, Herts) is pleased to announce the release of Measurement Computing’s (Norton, Massachusetts) universal analogue input module to the USB-2404 series of simultaneous data acquisition devices. The new module provides four channels of 24-bit universal analogue input with integrated signal conditioning.

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 USB-2404-UI can perform the following measurements:

·    Voltage
·    Current
·    Thermocouple
·    RTD (4-wire and 3-wire)
·    Resistance (4-wire and 2-wire
·    Bridge-based sensors (quarter-, half-, and full-bridge).

Measurement ranges vary for each type of measurement.

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 analogue 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 analogue 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.
