Electrical and Mechanical Specifications
*1. Includes the End Cover, and does not include projecting parts.
*2. Includes the End Cover. The weight of the End Cover is 82 g.
*3. Includes an SD Memory Card. The NX Unit power consumption to NX Units is not included.
*4. The inrush current that occurs when the supplied power is changed to ON from a continuous OFF state.
The inrush current may vary depending on the operating condition and other conditions. Therefore, select fuses, breakers, and external power
supply devices that have enough margin in characteristic and capacity, considering the condition under which the devices are used.
In particular, in case when you insert a switch to turn ON/OFF the DC power supplied from an external power supply, if the duration of an ON-
OFF-ON cycle is one second or less, the inrush control circuit may not function, which cause an inrush current of approximately 30 A/0.3 ms.
*5. The amount of current that can be passed constantly through the terminal. Do not exceed this current value when you use a through-wiring for
the Unit power supply.
*6. When the type of the I/O power supply to NX Units you use is the supply from NX bus, an Additional I/O Power Supply Unit is required. Refer

NX-series NX102 CPU Unit Hardware User’s Manual
(W593) for details.
