MCC 172 IEPE Measurement DAQ HAT for Raspberry Pi
MCC 172
IEPE Measurement DAQ HAT for Raspberry Pi
P/N: 6069-410-004 (MCC 172)
P/N:069-471-000 (MCC 172 with 2 coaxial cables)
The Measurement Computing MCC 172 is a voltage HAT (Hardware Attached on Top) designed for use with Raspberry Pi®. The MCC 172 features two channels for making sound and vibration measurements from IEPE sensors like accelerometers and microphones. The two 24-bit differential analog input channels simultaneously acquire data at rates up 51.2 kS/s. Users can turn IEPE excitation current on or off. Each channel has a dedicated A/D converter. Both ADCs share the same clock and are synchronized to start conversions at the same time for synchronous data. Multiple MCC 172 HATs can be synchronized to a single sampling clock. The clock is programmable for sampling rates between 51.2 kS/s to 200 S/s. The trigger input (terminal TRIG) is used to delay an input scan until a specified condition is met at the trigger input. HAT configuration parameters are stored in an on-board EEPROM that allows the Raspberry Pi to automatically set up the GPIO pins when the HAT is connected. The open-source MCC DAQ HAT Library of commands in C/C++ and Python allows users to develop applications on the Raspberry Pi using Linux. The MCC DAQ HAT Library supports operation with multiple MCC DAQ HATs running concurrently. Console based and user interface (UI) example programs are available for each API.
