FX3U-1PSU-5V Expanded Power Supply Unit Features
FX3U-1PSU-5V
Use this unit if not enough internal power capacity is available to supply power to the output expansion blocks or special expansion blocks added to an FX3G or FX3U sequencer (AC power type).
Use this unit if not enough internal power supply is available when the FX3 intelligent function unit is connected to an FX5U CPU unit.
FX5U CPU unit: Up to 2 units (FX5-1PSU-5V, FX3U-1PSU-5V) can be connected.
FX3G sequencer: Only 1 FX3U-1PSU-5V unit can be connected per system.
FX3U sequencer: Up to 2 FX3U-1PSU-5V units can be connected per system.
