The imc CRONOSflex Module (CRFX/HRENC-4) serves to measure signals whose time- or frequency information is to be captured. In contrast to the case with analog channels, to actual measurement
does not consist of repeated sampling at a fixed time interval. Instead, digital counters are used to determine either the count of pulses occurring or the time intervals between defined signal slope
events. For the time measurement/ maximum frequency, a resolution of approx. 3.9 ns (256MHz) is achieved. When using two-track sine/cosine signal encoders, conversion to digital values for determining the rotation direction and the absolute count of increments (full periods) is performed. Additionally, detailed information about the position can be gained by analog evaluation of
the sine/ cosine signal, which results in yet further increased resolution.

Highlights

• The HRENC-4 is both a digital comparator and serves the purposeof analog evaluation (sine / cosine signals).
• Fully conditioned (differential input and filter)
• 256MHz measurement time resolution
• Feedback of revolution speed etc. to precise time measurement

This amplifier is especially designed for sensors that are able to convert electrical, physical dimensions in frequency. These sensors spent in a "state of rest" (input parameter = 0) a frequency not equal
zero. The physical dimension combined with the scaling factor has to be entered into the basis card.
By means of taring in the dialog 'amplifier adjustment' this state of rest is tared as a zero position. Frequencies that are smaller than that state of rest will be notified as negative physical values.
