CAUTION
INPUT SPECIFICATIONS
1) The M2PRU’s output waveform is not uniform due to its
scaling method. The user must be aware that it may be
inconvenient for certain types of application.
2) The M2PRU is designed to accept at the maximum of 100
kHz, which may cause errors due to chattering in the input
pulses.
Excitation: Shortcircuit protection; limited to approx. 40 mA
at shortcircuit
■ Open Collector
Frequency range: 0 – 100 kHz
Pulse width time requirement: Min. 5 μsec. for ON and OFF
Sensing: Approx. 24 V DC @2 mA
Detecting levels: ≤ 400 Ω / 0.8 V for ON,
≥ 1200 Ω / 2.4 V for OFF
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 need improvement. Limit
the input frequency to 10 Hz at maximum.
■ Mechanical Contact
Frequency range: 0 – 30 Hz
Pulse width time requirement: Min. 10 msec. for ON and OFF
Sensing: Approx. 24 V DC @2 mA
Detecting levels: ≤ 400 Ω / 0.8 V for ON,
≥ 1200 Ω / 2.4 V for OFF

levels
GENERAL SPECIFICATIONS
Construction: Plug-in
Input impedance: ≥ 10 kΩ
Connection: M3 screw terminals (torque 0.8 N·m)
Screw terminal: Chromated steel (standard) or stainless
steel
Max. input voltage across the terminals: ±50 V
Detecting levels
DC coupled: ≥ 2 V DC for high level; ≤ 1 V DC for low level
Capacitor coupled: ≥ 2 Vp-p
Housing material: Flame-resistant resin (black)
Isolation: Input to output to power
■ Two-wire Current Pulse
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.
Frequency range: 0 – 100 kHz
Pulse width time requirement: Min. 5 μsec. for high and low
levels
Detecting levels:
≥ 10 mA for high level
*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.

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.)

■ SCALING FACTOR

spectively to each digit of the decimals and exponential as
shown below.
Output Rate = Input Rate × 0. (A)(B)(C)(D) × 10 –(E)

1.0000 × 10 –0 thr. 0.0001 × 10 –6
■ PULSE SENSING TYPE
[Examples]
Provided only when the voltage pulse input is selected. Factory set
to ‘DC coupling.’
Scaling factor 0.1440:
(A) = 1, (B) = 4, (C) = 4, (D) = 0, (E) = 0
Scaling factor 1.0000 is special:
When the DC offset is too large to detect by DC coupling, switch to
‘Capacitor coupling.’
(A) = 0, (B) = 0, (C) = 0, (D) = 0
■ PULSE WIDTH
Factory adjusted to a suitable value. Use only when the output
device (counter) is not able to read the output pulses.

the internal voltage drop value may increase with a shorter
