*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.
