CPU Power Supply
The CPU Power Supply is mounted to the rightmost slot of the CPU Rack.
Three models of Power Supplies are available: 100 to 120 VAC, 200 to 240
VAC, and 24 VDC. The following table summarizes the output capacity of the
three models and the current available for I/O Units mounted on the CPU
Rack.

Note
Be sure to keep the total power consumed by all the Units mounted
on a Rack within the value stated in the table above. For example, do
not mount I/O Units with a total current consumption of 6 A to a Rack
supplied by a 7 A Power Supply. As shown in the table above, the
available current for I/O Units is only 5 A. For details concerning cur-
rent consumption, refer to

START input
RUN output
Connect a 100 to 120 VAC or 200 to
240 VAC power source.
Short these terminals to select 100 to
120 VAC. Open them to select 200 to
240 VAC.
Ground this terminal at a resistance of
less than 100
Ω
to improve noise im-
munity or prevent electric shock.
Ground this terminal at a resistance
of less than 100
Ω
to prevent electric
shock.
Use these terminals to supply power
to DC Input Units. Use a separate
Power Supply if the I/O Unit requires
more than 0.8 A. If a current higher
than 0.8 A is output, the PC stops.
These terminals are short-circuited as
a factory-set condition. Remove the
short-circuit bracket to start or stop
the PC with an external signal. Nor-
mally, leave them short-circuited.
These terminals are turned ON dur-
ing RUN operation.
