3-1. Function of I/O Terminals
This section explains the function of I/O terminals.
3-1-1. Power cable terminals
Connect the power cable terminals to the 12 to 24V DC power supplies (Power capacity: 20W or more).
The terminals are ring-shaped for M4.
The following figure shows an example to connect the terminals to 12V DC switching power supplies.

3-1-2. Connecting the I/O cable
The end of an I/O cable is a ring terminal (for M3, only FG terminal: for M4).
The length of an I/O cable is 5 m. To extend the cable, use a terminal block, etc.
A label is attached to each I/O cable.
The following table shows the relationship between the label display and the function.
