Note
1. V terminals and G terminals are respectively connected internally. When the
I/O power is being supplied, the power can be supplied to the input devices
from the V terminals and G terminals. Current supplied in this way, however,
must be less than 1 A.
2. Make sure there are no more than 12 inputs are turned ON at the same time

Note
The vertical center of the Unit is 4.9 mm lower than the center of the DIN track.
The Unit therefore extends downward 41.4 mm (including the mounting hook)
from the DIN track center.
