Safety measures Conforms to cULus and EC Directives.

*1. Disconnect the Power Supply Units LG terminal from the GR terminal when testing insulation and dielectric strength.
       Testing the insulation and dielectric strength with the LG terminal and the GR terminals connected will damage
       internal circuits in the CPU Unit.
*2. Supported only when mounted to CPU Rack.
*3. The inrush current is given for a cold start at room temperature. The inrush control circuit uses a thermistor element
       with a low-temperature current control characteristic. If the ambient temperature is high or the PLC is hot-started, the
       thermistor will not be sufficiently cool, and the inrush currents given in the table may be exceeded by up to twice the
       given values. When selecting fuses or breakers for external circuits, allow sufficient margin in shut-off performance.
*4. Maintain an ambient storage temperature of −25 to 30°C and relative humidity of 25% to 70% when storing the Unit for
       longer than 3 months to keep the replacement notification function in optimum working condition.
*5. Change the applied voltage gradually using the adjuster on the Tester. If the full dielectric strength voltage is applied
       or turned OFF using the switch on the Tester, the generated impulse voltage may damage the Power Supply Unit.
*6. CJ1W-PD022 is not insulated between the primary DC power and secondary DC power.
*7. Internal components in the Power Supply Unit will deteriorate or be damaged if the Power Supply Unit is used for an
       extended period of time exceeding the power supply output capacity or if the outputs are shorted.

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.

Power Supply Units Max. current supplied Max. total power supplied
5 V 24 V (relay driving current)
CJ1W-PA205R 5.0 A 0.8 A 25 W
CJ1W-PA205C 5.0 A 0.8 A 25 W
CJ1W-PA202 2.8 A 0.4 A 14 W
CJ1W-PD025 5.0 A 0.8 A 25 W
CJ1W-PD022 2.0 A 0.4 A 19.6 W

Conditions 1 and 2 below must be satisfied.

Condition 1: Maximum Current

(1) Total Unit current consumption at 5 V ≤ (A) value
(2) Total Unit current consumption at 24 V ≤ (B) value

Condition 2: Maximum Power

(1) × 5 V + (2) × 24 V ≤ (C) value

Example: Calculating Total Current and Power Consumption

Example: When the Following Units are Mounted to a CJ-series CPU Rack Using a CJ1W-PA202 Power Supply Unit

Result 1.92 A ( ≤ 2.8 A) 0.096 A ( ≤ 0.4 A)
Power consumption Total 1.92 × 5 V = 9.60 W 0.096 A × 24 V = 2.304 W
Result 9.60 + 2.304 = 11.904 W ( ≤ 14 W)
