Explanation of Functions
Pulse Input (/PM1 Option)
Contact or open collector signal pulses are input to the dedicated input terminals.
• Three inputs are available. However, the instrument can be expanded for up to 8
inputs.
• Pulses of 100 Hz or less whose Low (closed) and High (open) pulse widths are both 5
ms or more can be counted.
• The FX100 counts the following changes.
Contact signal pulse input: contact changes from open to closed
Open collector signal: input terminal level changes from High to Low
More than or equal to 5 ms each
Less than or equal to 100Hz

Counting Input Pulses
You can count and display the number of pulses input at each scan interval using
computation channels.
Sum Value
To display the pulse sum value, an equation is entered on the computation channels
to be displayed.
Number of Pulses per Unit Time
To display the number of pulses per unit time (1 s, 1 min, and 1hour), an equation is
entered on the computation channels to be displayed.
Using computation channels, sum of pulses are calculated and displayed.
For information about the computation function, see section 1.6, “
Computation Function and
Report Function (/M1, /PM1 Option)
”.
Note
The pulse detection interval is approximately 3.9 ms. If the pulse width is not 5 ms or greater,
the FX100 may not be able to detect it.
Pulse signal
This change cannot be detected.
Pulse detection interval (approximately 3.9 ms)
Less than 5 ms
