Description
The AC power supply has [L] and [N] terminals.
The DC power supply has [+] and [-] terminals.
For external wiring, refer toPage 172 Power Supply Wiring.
The 24VDC service power supply has [0V] and [24V] terminals.
Between [0V] and [0V] terminals and between [24V] and [24V] terminals of the FX5U-64M and FX5U-
80M (AC power supply), the terminals are connected internally, and an external short-circuit is not
required.
The DC power supply type does not have a 24VDC service power supply. [] indicates vacant terminals.
Do not wire [] terminals.
Both AC and DC power supply types have the same input terminals;
however, the external input wiring differs from each other.
One common terminal covers 3 or 4 output points. For external wiring, refer toPage 175 Input Wiring.
Output points covered by one common terminal are as follows.
• FX5S CPU module, FX5UJ CPU module: 3 or 4 points
• FX5U CPU module: 4 or 8 points
The output numbers (Y) inside the thick "divider lines" are connected to common.
For transistor output (source) type, the "COM" terminal is the "+V" terminal.
