The functions of DIP switch S1 and jumper CN15 are shown in the following table.
îš„ Sinking/Sourcing Mode
The input terminal logic can be switched between sinking mode (0-V common) and sourcing mode (+24V
common) by using the terminals SN, SC, and SP. An external power supply is also supported, providing more
freedom in signal input methods.
