MCC 172

IEPE Measurement DAQ HAT for Raspberry Pi®

KEY HIGHLIGHTS

The MCC 172 is a two channel DAQ HAT for making sound and vibration measurements from IEPE sensors like accelerometers and microphones. It features a 24-bit A/D per channel and a maximum sample rate of 51.2 kS/s/Ch. Up to eight MCC HATs can be stacked onto one Raspberry Pi allowing users to create high-channel count, multifunction solutions of different signal types.

All MCC DAQ HATs include easy-to-use C/C++® and Python™ open-source libraries and examples for taking reliable, quality measurements quickly.

NOTE: Raspberry Pi is not included with the MCC 172.

Answers

No, the MCC 172 does not have the circuitry for detecting a faulty accelerometer. The easiest way is to measure its bias voltage using a multimeter. You can use a splitter and connect a DC multimeter in line to measure the devices Bias voltage. If it’s at the supply voltage (23V) or at 0 volts, then there is a problem with your cabling or the device itself. If the meter reads somewhere in the middle, then your device is OK.

I would like to start an acquisition on multiple boards simultaneously but started by software. Does the master device send a trigger signal to the slaves like it works for the clock? If not, can I trigger it by a GPIO from the RPi on the shared trigger line (GPIO19?)?

Answers

The MCC 172 is designed to operate with one or a multiple of MCC 172s, but an external trigger signal to the Master ‘172 is a requirement. Connecting the TRIG input to an unused GPIO is possible however MCC does not provide support or suggestions on how to implement that.

I would like to connect an IEPE accelerometer to a RaspberryPi and i was wondering whether de MCC172 includes any kind on anti-aliasing filter in order to satisfy the Nyquist–Shannon sampling rule over a frequency band of interest

Answers

Yes, the MCC 172 includes an anti-aliasing filter. Alias-free bandwidth is calculated using the following formula: 0.453 * fS, Alias rejection 100 dB @ 51.2 kS/s. A description and specifications on the filters that are included with the MCC 172 can be found in our User’s Guide at: https://mccdaq.github.io/daqhats/overview.html#id37

What is the maximum sample rate that we can collect with Raspberry Pi 4? For single MCC172 and two.

Answers

For a single channel, the maximum sampling rate is: 51.2 kS/s/ch max. For a single MCC 172 HAT, 51.2 kS/s/ch × 2 channels: 102.4 kS/s max. For Multiple MCC 172 HATs: Up to 307.2 kS/s aggregate. This is dependent on the load on the Raspberry Pi processor and the SPI interface. Note: when using multiple MCC 172s on one RPi 4, 307.2 kS/s / 51.2 kS/s = 6 channels running at full speed. This equates to three, MCC 172 HATs operating at their maximum sampling rate per channel.

Hi, I’m trying to connect an accelerometer to Raspberry Pi. (accelerometer: https://ctconline.com/products/ctc-line/industrial-accelerometers/100-mv-g-standard-size/?prd=AC102 ) Is MCC-172 suitable for this application?

Answers

Yes, the MCC 172 will be compatible with the AC102 accelerometer that you listed in your question. The MCC 172 supports a 23 V max excitation source and a 4 mA constant current. As long as the accelerometer specifications falls in line with the MCC 172…which it does, you will be all set.
