The CNT-Scan MiniModule is a high-precision measurement module for frequencies up to 300 kHz, for measurement of duty cycles/PWM signals, cycle/pulse duration measurement as well as event counting.

Speed measurement (RPM) is calculated directly in the module and displayed as value on the CAN bus. Additionally, the time/event offset between adjacent channels can be measured.  The inputs are completely electrically isolated and connected sensors can be powered directly from the module. Each measurement mode requires only one signal input, however, one signal input can simultaneously collect two measurement parameters from the same physical signal - thereby allowing for up to 8 logical channels.

User selectable per-channel triggering for On and Off signal levels is supported. The On-/Off-Trigger thresholds are individually adjustable for each channel. Switchable AC coupling allows for suppression of undesired DC offset of the input signal.
High frequencies as well as low frequencies are automatically captured with constant high accuracy.  This applies also to short and long periods and pulses.
