By implementing the terminal block called IO Power (J8), you can supply power to the
digital I/O from an internal 24V power supply or external power supply. The left two
blocks are composed of internal 24V(INT_24V), GND and the right two blocks are
composed of external 24V(EXT_24V), GND. They can supply power from the outside
to the digital I/O.
Basically, internal 24V power is supplied for use. The basic power supply configuration
is as follows.
INV
Internal 24 V I/O power supply
Current limit: 2 A
Typ. DC 24 V
Min. DC 23 V
Max. DC 26 V
ING
Internal 24 V I/O GND
EXV
External 24 V I/O power supply
EXG
External 24 V I/O GND
If the digital I/O power supply provided from the inside of the controller is not
sufficient, then you can connect an additional power supply externally. If an
internal/external power supply is used, then the current limit of 2A is applied.
If the digital I/O requires more current, then you can connect an external power supply
as follows.
Note
If the current is over the upper limit, then the digital I/O fuse can blow off.
If the fuse is blown off, you need to replace it.
You can configure the terminal block called as Power Switch (J9) to use it as an external
power supply switch.
