Counter/Encoder input connections
The DEWE-321x is suited with synchronous 32-bit advanced counter and digital inputs. In addition to the
basic counter function like simple event counting, up/down counting and gated event counting also period
time, pulse width, two-edge separation, frequency and all encoder measurements are supported.
All counter inputs can also be used as digital inputs. In addition to the basic counter input selections, the
ADC clock can also be used as counter source. The gure below shows the block diagram of the counter
and input overvoltage protection.
