Firetail DAQ releases new analogue input devices

Supplier News

Firetail DAQ , Australian Distributor of low-cost data acquisition products from Measurement Computing Corp (MCC), has released two new 8-channel USB analogue input devices, the USB-TC-AI and the USB-TEMP-AI.

These new products feature four differential temperature inputs, and four differential or single-ended voltage inputs with programmable gain and are modelled after the highly successful USB-TC and the USB-TEMP products, which have all eight input channels configured for temperature.

These new AI versions of our USB-TC and TEMP products fill a gap in the test and measurement community for accurate temperature and voltage measurements on a single USB device and provide flexibility and high performance.

The USB-TC-AI temperature channels support J, K, R, S, T, N, E, and B type thermocouples. The input ranges for the four voltage channels are software programmable for ±10 V, ±5 V, ±2.5 V, ±1.25 V.

The USB-TEMP-AI supports the same thermocouple types as the USB-TC-AI, plus RTDs, thermistors and semiconductor temperature sensors, and has the same voltage input ranges.

The USB-TC-AI and the USB-TEMP-AI are USB 2.0 full-speed, modules supported under current popular Microsoft Windows operating systems and are both fully compatible with both USB 1.1 and USB 2.0 ports.

Separate, 24-bit analogue-to-digital (A/D) converters are provided for each pair of analogue inputs.

And both devices, in addition to the temperature and voltage input capabilities, provide eight independent, TTL-compatible digital I/O channels to monitor TTL-level inputs, communicate with external devices and to generate alarms.

The digital I/O channels are software programmable for either input or output.

Both the USB-TC-AI and USB-TEMP-AI have an integrated cold junction compensation (CJC) sensor for thermocouple measurements.

The USB-TEMP-AI also has built-in current excitation sources for resistive sensor measurements.

The USB-TC-AI and USB-TEMP-AI ship with an impressive array of software included in the MCC DAQ Software CD.

The disk includes good applications, drivers and libraries that meet the needs of programmers and nonprogrammers alike.
