NPN and PNP Digital Inputs Configuration
Cerus X-Series drive control can be configured to Sink (NPN) or Source (PNP) modes by providing proper
wiring and installing/removing jumper on ter24, COM and DCM.
The picture above shows four possible digital inputs configurations:
1.
Sink (NPN) mode with internal 24VDC power source (Default).
Install jumper b24 and COM
terminals. Connect dry contact or NPN transistor output from external control device to desired digital
input and DCM terminals. When contact is closed or transistor is in conducting state, digital input will
be activated by internal power supply.
2.
Source (PNP) mode with internal 24VDC power source.
Install jumper between DCM and COM termi

nals. Connect dry contact or PNP transistor output from external control device to desired digital input
and +24 terminals. When contact is closed or transistor is in conducting state, digital input will be acti
-
vated by internal power supply.
3.
Sink (NPN) mode with external 24VDC power source.
Remove any jumpers b24 and COM or
DCM and CM terminals. Connect positive terminal of external power supply to COM terminal. Connect
dry contact or NPN transistor output from external control device to desired digital input and negative
terminal of external power supply. When contact is closed or transistor is in conducting state, digital
input will be activated by external power supply.
4.
Source (PNP) mode with external 24VDC power source.
Remove any jumpers b24 and COM
or DCM and CM terminals. Connect negative terminal of external power supply to COM terminal. Con

itive terminal of external power supply. When contact is closed or transistor is in conducting state,
digital input will be activated by external power supply.
