CAN CNT MiniModules

The CAN-based CNT MiniModules (CNTMM) “classic” and “pro” are high-precision measurement modules designed for measuring frequencies, pulse widths, incremental displacement measurements, rotation angles, position measurement, event counting and period measurements.

Both module versions feature four electrically isolated measurement inputs for measuring:

  • Frequencies: 0.1 Hz to 300 kHz
  • Cycle / pulse duration: 1 µs to 100 s
  • Duty cycle / PWM: 0 % to 100 %
  • Event counting: 0 to 65535 (CNTMM 4 classic), 0 to > 4 billions (CNTMM 4 pro)
  • Speed: 0.01 rpm to 60,000 rpm
  • Time offsets: 1 µs to 100 s
  • In addition, CNTMM 4 pro provides up and down counting via pulse/direction or quadrature signal.

Each physical channel can read two measurement values simultaneously, which means that CNTMM modules provide eight logical channels. On/off trigger thresholds are adjustable per channel and feature a switchable AC coupling. Also, these modules are equipped with a galvanically isolated sensor excitation.

Measurement of analog voltage from sensors

Regardless of whether it involves measurements of oil circuit pressure, the flow rate in the cooling circuit or a vehicle's ground clearance, many sensors convert their respective measured quantity into an analog voltage which can be processed in one of CSM's analog measurement modules.
