2-2-3 Wiring
Power Supply
Apply 100 to 240 VAC or 12 to 24 VDC to terminals 8 and 9.
Open Collector Input
Connect the pulse output from sensor A to terminal 1.
Connect the pulse output from sensor B to terminal 2.
Terminals 10 and 11 are exclusively used for a power supply with an output of
80 mA at 12 VDC to sensors A or B. If power is supplied to the sensors A or B
from a different power source, do not use terminal 10. Do not connect a sensor
with open collector output to terminal 10.
Refer to the following for sensor connections.
Sensor (with NPN output)
Sensor (with PNP output)
+12 V
+12 V
·
Residual voltage with sensor turned on: 3 V max.
·
Current leakage with sensor turned off: 1.5 mA max.
·
Switching load current: 20 mA or greater. Must be able to dependable switch
a load current of 5 mA max.
Photoelectric sensors, proximity sensors, rotary encoders, and relays can be
connected as sensors to the K3NP.
Voltage Pulse Input
Connect the pulse output of sensor A to terminal 3.
Connect the pulse output of sensor B to terminal 4.
Terminals 10 and 11 are exclusively used for a power supply with an output of
80 mA at 12 VDC to sensors A or B. If power is supplied to the sensors A or B
from a different power source, do not use terminal 10. Do not connect a sensor
with voltage pulse output to terminal 10.
Refer to the following for sensor connections.
Sensor
+12 V
H level (sensor output ON): 4.5 to 30 VDC
L level (sensor output OFF): --30 to 2 VDC
Auxiliary Power Supply
Terminals 10 and 11 are exclusively used for power supply to sensors with an
output of 80 mA at 12 VDC
