If the source input mode is selected, the function of the multi-function control; terminal is active when it
is shorted with PC or connected with the external PLC. At this mode, the current flows into the
corresponding terminal when it is ‘on’. Terminal PC is common to the contact input signals. When using
an external power supply for transistor output, please use terminal SD as a common to prevent
malfunction caused by leakage current.
