Sinking/Sourcing Mode (NPN/PNP Selection)
The input terminal logic can be switched between sinking mode (0-V common, NPN) and
sourcing mode (+24V common, PNP) for digital inputs S1 to S7 by setting jumper CN1. An
external power supply is also supported in both sinking and sourcing modes, providing more
freedom in signal input methods.
