PULSE AMPLITUDE (rotary switch)

  (*) Factory setting

For voltage pulse input, select the pulse amplitude (V p-p) 
among the switch positions 0 through 6.  For open collector, 
mechanical contact or two-wire current pulse input, set the 
switch to 7.  DO NOT SET to 8 or 9.  The power supply to the 
unit must be turned off when changing the setting.

‘High’ noise filter is usable for the input frequency 10 Hz or 
lower range, and ‘Low’ filter is usable for 500 Hz or lower.  
For a mechanical contact input, ‘High’ setting is recom-
mended in order to eliminate unwanted counts caused by 
chattering.

 

EXAMPLE 1: VOLTAGE PULSE with Amplitude 5V p-p, DC Offset 2.5V, Count Range 0 – 1000
