FX2N-64CL-M CC-Link/LT Master Block System Configuration 4
4-4
4.3 Installation concept and condition of power adapter or dedicated power supply
At least one power adapter or dedicated power supply is required for each CC-Link/LT system.
4.3.1 Power adapter installation concept
When constructing a system using only one power adapter, the following three conditions
should be satisfied.
1) Total current consumption of remote modules, I/O equipment and the master block
receiving power from power adapter (including current consumption at startup)
≤
5 A
2) To operate the system in a stable environment, the voltage drop* should be equivalent to or
less than 3.6V.
3) As the minimum operating voltage from the power adapter is 20.4V for each remote module,
Supply voltage to power adapter - Voltage drop*
≥
20.4 V
If the total current consumption or voltage drop* is large, the power adapter position should be
changed or additional power adapters should be installed.
It is necessary to consider the maximum output voltage, rated output current and maximum
output current for the general-purpose power supply connected to the power adapter.

* Voltage drop from the power adapter to the master station and remote modules (when
operating temperature is 20
°
C)
4.3.2 Power adapter installation condition
The condition for installing the power adapter supplying the power to the CC-Link/LT varies
depending on the connected equipment and wiring length. For details on the condition for
installing the CL1PAD1 (power adapter), refer to the separate document "CC-Link/LT: Power
