Terminal function description
To provide 24V power supply, generally used as a
digital input and output terminal power supply and
external sensor power
The factory default setting is connected PLC with
+24V
Terminal for on-off input high and low level switch
When using the external signal to drive DI1~DI5, it
will disconnect the connector slip of PLC with the
+24V
