Explanation of Functions
1.7 Functions of the 10-CH, High-Speed Digital
Input Module (-D05, -D24)
The -D05 module is equipped with ten inputs and measures non-voltage contact, open
collector, and 5-V logic inputs at a minimum measurement interval of 10 ms.
The -D24 module is equipped with ten inputs and measures 24 V logic inputs at a
minimum measurement interval of 10 ms.

Measurement Interval
You can select a measurement interval of 10 ms, 50 ms, 100 ms, 200 ms, 500 ms, 1 s, 2 s,
5 s, 10 s, 20 s, 30 s, or 60 s.
Filters
The module detects ON/OFF as shown below to prevent receiving chattering effects. If
the measurement interval is set at a value greater than four times the chattering period,
measurement is possible in which chattering effects are avoided.
• Measurement interval of 5 s or less: Use the wider of the ON/OFF width of the
detectionperiod(approximately75%to90%ofthemeasurementinterval)
