2-4 Input Wiring Diagram
1.NPN photoelectric sensor wiring
；
The equipment defaults to the initial logic. The photoelectric sensor shall be NPN type,
and the photoelectric sensor shall be connected to signal terminals 1, 2 and 3. The
corresponding line sequence is shown in the table:

Note: The high level voltage of input terminal is ranged from 5v to 24v
。
2.Switch connection
；
The switch connection defaults to the initial logic. Connecting the switch to signal
terminals 2 and 3, and when the switch is pressed, the trigger takes effect. The line
sequence is shown in the table below

3.Relay trigger wiring
；
The equipment defaults to the initial logic and the relay is connected to signal terminals 2
and 3. When the rated voltage is applied, the trigger takes effect. The corresponding line
sequence is shown in the table below
