Power Supply Module Cat. No. 1794-PS13
Wiring
Terminals A, B, and C are 120/230V supply terminals. Terminals D, E,
and F are available to daisychain this 120/230V power to other
1794-PS13 power supplies. If supplying 120V ac to the power supply,
you can also power the ac modules in the adjacent system.
1. Connect the 120/230V ac power to the left side terminals on
the connectors on the left side of the module as follows:
2. Connect terminal G (+24V dc) to the +24V dc terminal on the
first adapter.
3. Connect terminal H (+24V dc common) to the +24V dc
common terminal on the first adapter.
4. Repeat steps 3 and 4 using terminals I and J for the second
adapter.
5. Connections D, E and F are used to pass 120/230V ac power
to adjacent 1794-PS13 power supplies.

ATTENTION
!
The 1794-PS13 power supply provides sufficient
24V dc power to operate up to 4 adapter
modules. Do not attempt to operate an entire
FLEX I/O system with this power supply.
