24V I/O can be managed in the following ways:
◊ Direct : 24VI supply with pins 5 - 6 of PS being free (see paragraph
3.2.2 figure
a )
J1 connector: jumpers of I/O and ADC cards to be made in position 1-2.
◊
Indirect
: 24VI supply with pins 5 and 6 of the PS: make jumpers or cut them out
from a contact (see paragraph
3.2.2 figure b
).
24VI supply, which in this way can be cut out from the outside (enabled/disabled),
is re-closed on 24VE line.
◊
External
: with external 24V supply connected to pin 6 and pin 7 of the PS (see
paragraph
3.2.2 figures c and d )
.

24VI is cut off on the PS between pin 5 and pin 6. Thus, 24V supply of I/Os can be enabled and
disabled independently of the control device.
