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
immunity 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 operate
on more than 0.8 A. If a current higher
than 0.8 A is output, the PC stops.
These terminals are used to supply
external DC Input Units. If the Unit re-
quires more than 0.8 A a separate
supply must be used. The PC shuts off
