Fig.3-23 External power supply open collector NPN connection
ATTENTION:
When external power supply is utilized, the jumper between +24V and PLC must be removed.
The voltage range of external power supply should be DC20～30V, otherwise normal operation could
not be assured and/or hazard of equipment damage exists.
