Using the I/O Receptacle
Insert a small slotted screwdriver into the upper or lower
slot of the hole you want to connect a wire to (AWG No.
26 to 20). Hold down the screwdriver and insert the wire,
then release the screwdriver.
Do not use excessive force when inserting the screwdriver
into the slot. Doing so may result in damage.
Repeat this procedure to connect all required wires.
Wiring Diagram 1 for Sensor Input
Wiring Diagram 2 for Sensor Input
When the wiring diagram 2 is used, the NSR is not
electrically isolated, so be sure to construct external
circuits that will not produce noise, excess voltage, or
overcurrents.
