The above diagram (PNP output) is a reference wiring diagram for connecting an input device with PNP
output to the SmartAXIS source input. By installing an external resistor, an input device with PNP output can
be connected. When installing an external resistor, note the following points when wiring and checking the
operation.
When the external power supply voltage is 24V DC, an external resistor with a resistance value of 1kΩ and a rated voltage
of 2W or more (safety factor more than 3 times) is recommended. In this case, the current flowing through the external
resistor is as follows.
When the PNP output of the input device is off: Approximately 4.15 mA
When the PNP output of the input device is on: Approximately 24.0 mA
For the digital input internal circuit (source input), see "Digital Input Internal Circuits" on page 2-12.
The on/off operation of the PNP output of the input device and the
source
input of SmartAXIS is reversed.
When the PNP output of the input device is off, the
source
input of SmartAXIS is on.
When the PNP output of the input device is on, the
source
input of SmartAXIS is off.
When the external power supply of the input device is off, the source
input of SmartAXIS
is on.
