If "Source Input” mode is selected, when the multi-function digital input terminal is short-circuited to PC or connected to
an external PLC, the function of this terminal is valid. In this mode, the current flows into the corresponding terminal
when it is short. Terminal “PC” is common terminal of the contact input signals. When the output transistor is powered
by an external power supply, use SD terminal as a common terminal to prevent malfunction due to leakage current.

 Wires connection
For the control circuit wiring, strip off the sheath of a cable, and use it with a blade terminal. For a single wire, strip off
the sheath of the wire and apply directly.
(1) Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur
with neighboring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.
