MCC USB-TEMP
The USB-TEMP is MCC’s 8-channel, 24-bit USB temperature device that reads thermocouples, 100 Ω platinum RTDs, thermistors and LM35-style semiconductor sensors, with 500 VDC isolation and eight digital I/O lines. Labs buy it when one box has to handle a mix of sensor types.

Sensor types and channels
The USB-TEMP has eight differential inputs, with one 24-bit converter for each pair of channels. You set the sensor category in software. Supported types are thermocouples (J, K, R, S, T, N, E and B), 100 Ω platinum RTDs and thermistors in 2-, 3- or 4-wire connections, and semiconductor sensors such as the LM35 or TMP35. Throughput is 2 S/s per channel, 16 S/s across all eight. Field wiring is isolated from USB to 500 VDC minimum. The RTD calculator converts Pt100 resistance to temperature if you want to check a reading by hand.
USB-TEMP vs USB-TC
Both share a family datasheet, the same 2 S/s per channel rate and the same isolation rating. The USB-TC reads thermocouples only and costs less, $430 at Digilent against about $645 for the USB-TEMP at Mouser at the time of writing. Pick the USB-TEMP if any channel needs an RTD or thermistor. Digilent also sells the USB-TEMP-AI, which mixes temperature and voltage inputs.
Software on each operating system
On Windows, InstaCal handles configuration and DAQami logs data, with the Universal Library for programming. On Linux and macOS, uldaq lists the USB-TEMP as supported, so it is scriptable in C or Python, though MCC ships no logging app there. The thermocouple measurement guide covers wiring for the thermocouple channels. DAQAtlas, which is in development, reads the USB-TEMP through uldaq and can log it on one timeline with voltage hardware from other vendors.
Questions
Can the USB-TEMP read RTDs and thermocouples at the same time?
The sensor category is software-programmable on the device, which supports thermocouples, 100 Ω platinum RTDs, thermistors and semiconductor sensors. Check MCC’s user guide for how channels are grouped when mixing types.
Does the USB-TEMP work on Linux or macOS?
Yes. MCC’s uldaq library supports the USB-TEMP on Linux and macOS. InstaCal and DAQami are Windows only.
How fast does the USB-TEMP sample?
2 samples per second per channel, 16 S/s total across all eight inputs.
