MODEL: M2PRU
most relay types, however, an external CR filter as indicated
below, could be added if the user need improvement. Limit
the input frequency to 10 Hz at maximum.

GENERAL SPECIFICATIONS
Construction: Plug-in
Connection: M3 screw terminals (torque 0.8 N·m)
Housing material: Flame-resistant resin (black)
Isolation: Input to output to power
Chattering protection: Filter provided for mechanical
contact input (time constant: approx. 1 msec.)
Input pulse sensing: DC coupled; capacitor coupling
(automatic trigger*) is field selectable with the side DIP
switch for the voltage pulse input.
*Capacitor coupling, with which the detecting levels are
automatically set within two peaks of the waveforms, is
effective way to detect those with DC offset. However, it
may be ineffective if the duty ratio is extremely high or low.
The automatic trigger method can compensate such
irregular pulses.
Scaling factor adjustment: 10-position rotary switch (front);
1.0000 × 10

Output pulse width adjustment: Single-turn screwdriver
adjustment (front); 5 μsec. – 400 msec. (one-shot type);
Factory set to 5 μsec. except for the mechanical contact
input set to 15 msec. or AC/DC switch output set to 500
μsec.
(Min. 400 μsec. recommended for AC/DC switch output of
which the internal voltage drop value may increase with a
shorter pulse width.)
Output pulse width range selector: Double-throw SW (front)
