5.8.23 Pro-Comp-16 Rev. A
The input module Pro-Comp-16 Rev. A provides 16 input channels with a com-
parator each. The analog signals are acquired parallel and converted with a
10-bit resolution. Depending on switching thresholds, which are separately
adjustable by software for each channel, digital signals are generated from
these measurement values (1/0).

The input voltage range of the module is between -2V…+8.23V, other voltage
ranges on request. The signals are acquired with 20MHz per channel.
Providing information Information about the acquired signals is available per software:
– The digital signals (1/0) of all input channels
– The current converted measurement values
– The maximum and minimum of the acquired measurement values
– The last 1024 measurement values of 2 selected channels
– The digital signals (1/0) of measurement differences
After all measurement values have been acquired they are evaluated
quasi-differential, which means that for all 8 channel pairs (1/2, 3/4, ...,
15/16) the differences of the measurement vaues is calculated. Depend-
ing on the switching thresholds, digital signals (1/0) are generated from
these differences, which can be selected via software.
