          *1 N-bus is the name of KEYENCE's wiring-saving system for sensors.
          *2 Varies with the sensors connected.
          *3 Indicates the current that can be supplied to the NU-PD1 and to the sensors linked to the NU-PD1.
          *4 Be sure to be used within the supply-voltage range of the sensor connecting to the NU-PD1.
          *5 Exclusive of the current supplied to the sensors connected.
          *6 1 to 2 units connected: -10 to +55 °C 14 to 131 °F, 3 to 10 units connected: -10 to +50 °C 14 to 122 °F,
          11 to 16 units connected: -10 to +45 °C 14 to 113 °F
          When a two-output type of sensor is connected, the sensor is counted as two units.
