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.
