Timing Chart
Each signal’s level indicates whether the contact is in the on or off state. When using the current
source (PNP) setting, the signal level will be the same as the EXT I/O connector’s voltage level.
When using the current sink (NPN) setting, the HI and LO voltage levels will be reversed.
Timing from the start of measurement to acquisition of judgment results
