Wiring the external terminal module UB-10-OT32A:
Transistor-P (sourcing)
Voltage specifications
12~24 VDC, 0.1 A
Wiring the external terminal module UB-10-OR16B:
4.9 Wiring Digital Input/Output Terminals
4.9.1 Wiring Digital Input Terminals
NPN(Sink) and PNP(Source)
The input signal is the 24 VDC power input. Sinking and sourcing are current driving capabilities of a circuit. They are
defined as follows.
NPN(Sink)
PNP(Source)
Sinking=The current flows into the common terminal S/S.
Souring=The current flows from the common terminal
S/S.
