5.9 10-CH, Pulse Input Module (MX114)
Specifications
Style number: S3
Number of Inputs: 10
Input type: Pull up internally at approx. 5 V/approx. 5 kΩ, non-isolated
between channels
Measurement interval: Select 100 ms, 200 ms, 500 ms, 1 s, 2 s, 5 s, 10 s, 20 s, 30 s, or
60 s.
Input types: Contact (non-voltage contact, open collector), LEVEL (5-V logic)
Rated measuring range:
0 to 30000
However when using the SNTP time synchronization function,
the measurement interval becomes that when the next time
synchronization is executed, and the rated measuring range at
that time must not be exceeded.

60 s 54 s to 66 s
Measurement accuracy:
Count ± 1 pulse (note that time axis accuracy (time accuracy) is
not included).
For integration computation, the following accuracies are added.
Computation start: + no. of integrations in the MATH interval
Computation stop: + no. of integrations in the MATH interval
Resolution: 1
Filter: First-order lag filter (digital filter):
Measurement interval of 5 s or less: The wider of the ON/OFF
width of the interval of
approximately 75–90% of
the measurement interval.
Measurement interval of 5 s or more: The wider of the ON/OFF
width of approximately 4.5
seconds.
Chattering filter (analog filter)
Turn on to remove chattering (of up to 5 ms)
Can be turned ON/OFF on individual channels.
Measurement mode RATE (count instantaneous mode):
Outputs the input number of pulses at the specified interval.
Input range: 10000 count/s or less
(plus over if the count within the measurement range exceeds
31500)
Minimum input pulse width: 40 μs
Input threshold level: Contact (non-voltage contact or open collector):
Counts when changing from contact open (100 kΩ or more) to
contact close (100 Ω or less)
LEVEL (5 V logic):
Counts when changing from 1 V or less to 3 V or more.
Hysteresis width: Approximately 0.1 V
