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/O

FF widths of the

detection period (approximately 75 to 90% of the measurement interval)
