8.2 Timing Chart
The levels of each signal indicate the ON/OFF status of the contacts. In the case of the current
source (PNP) setting, the signal levels are the same as the voltage level of the EXT.I/O terminals.
In the case of the current sink (NPN) setting, the High and Low voltage levels are reversed.
