CAUTION
The W5PA is designed to accept at the maximum of 100 kHz, which may cause errors due to chattering in the input pulses.
A filter circuitry (time constant: approx. 1 msec.) is incorporated to eliminate unwanted chattering when the mechanical contact input is specified. It is effective for most relay types, however, an external CR filter as indicated below, could be added if the user needs improvement. Limit the input frequency to 10 Hz at maximum.
