Precautions for Use
Compatible CPU Models
NJ-PA3001/NJ-PD3001 are dedicated for NJ-series.
Please make sure to use NJ-PA3001/NJ-PD3001 for all products including NJ-series CPU rack and expansion rack.
Power Supply Units Current Consumption
Checking Current Consumption and Power Consumption
After selecting a Power Supply Unit based on considerations such as the power supply voltage, calculate the current and power requirements for
each Rack.
Condition 1: Current Requirements
There are two voltage groups for internal power consumption: 5 V and 24 V.
Current consumption at 5 V (internal logic power supply)
Current consumption at 24 V (relay driving power supply)
Condition 2: Power Requirements
For each Rack, the upper limits are determined for the current and power that can be provided to the mounted Units. Design the system so that
the total current consumption for all the mounted Units does not exceed the maximum total power or the maximum current supplied for the voltage
groups shown in the following tables.
The maximum current and total power supplied for CPU Racks and Expansion Racks according to the Power Supply Unit model are shown below.
Note: 1. For CPU Racks, include the CPU Unit current and power consumption in the calculations. When expanding, also include the current and
power consumption of the I/O Control Unit in the calculations.
2. For Expansion Racks, include the I/O Interface Unit current and power consumption in the calculations.
