the internal or external power supplies
The solution described herein feature the following structure:
–
the 24 Vdc power supply is delivered by the internal power supply AMS-ASM32 or
taken from outside source through the X30
–
the 24 Vdc power supply for the I/O user's modules (direct and cut power supply)
can be taken from the X106/SDM connector, at the disposal of the user.

a.
Carry out the circuit as shown in the outline wiring diagram in
power supply cutoff circuit on X106/SDM: outline diagram on page
b.
If necessary, depending on the user choice for the circuitry, deliver the 24 Vdc
power supply through the X30 connector. In that case the JP200 position shall be
adjusted (refer to
par. 7.3 Selecting the 24 Vdc power supply source on page
c.
Power the I/O modules taking the power supplies on the X106/SDM connector.
