[example] (sink logic)

Note1)The above is a method to perform analog input(O/OI) by voltage input. It is necessary for SW6

on the board to be set for voltage input(default).

Note2) If you want to connect a relay to an intelligent output terminal, please connect a surge

absorbing diode in parallel with the relay. The output circuit may malfunction by voltage surge.

(3) Switching the input control logic

- In the factory setting, and intelligent input terminals is the sink logic.

To switch the input control logic to the source logic, remove the jumper connecting terminals P24 and

PLC on the control circuit block, and then connect terminals PLC and L with the jumper.
