*1 When using the power PoE power receiving function, use the STP cable or Category 5 or higher UTP cable. 2. The number of connectable units is not limited when using a switch. *2 When using the switch, there is no limit on the number of units that can be connected. *3 'N-bus' is the name of KEYENCE's wiring-saving system for sensor amplifi ers. *4 Depends on the sensor amplifi ers connected. 5. Value for the current which can be supplied to this unit or to a sensor amplifi er unit connected to this unit. *5 This is the current that can be supplied to the main unit or to the sensor amplifier connected to the main unit. *6 Varies according to the working ambient temperature. (-20 to 45 °C: 360 mA or less, 45 to 50 °C: 260 mA or less, 50 to 55 °C: 140 mA or less) *7 Power which can be supplied to the sensor amplifi er when using the PoE power receiving function. 7 *8 Current to be supplied to the connected sensor amplifi er is not included.
