In the I/O circuit drive, you can use a built-in service power source (24 V DC, 200mA or less).
If connecting a load with capacity exceeding 200mA, use an external power source.

The I/O signal circuits (terminal No.3 to 22) is insulated by a photocoupler from the controller internal circuit.
However, the service power source (24 V DC) is connected to the controller internal circuit (primary side
commercial power source and secondary side circuit are insulated).
As a result for the I/O signal circuit wiring, use an external power source as necessary.

Be careful about applying excess voltage or noise, etc., to each terminal.
