FILTER
• The M2PRU is designed to accept at the maximum of 100
kHz, which may cause errors due to chattering in the in-
put pulses.
A filter circuitry (time constant: approx. 1 msec.) is in-
corporated to eliminate unwanted chattering when the
mechanical contact input is specified. It is effective for
most relay types, however, an external CR filter as indi-
cated below, could be added if the user need improvement.
Limit the input frequency to 10 Hz at maximum.
