Output module
Low battery alarm
(lamp or buzzer)
This relay turns on
when the CPU module
starts running by SM403.
Power to the output
devices is shut off
when the stop switch
turns off.
The circuit is
interlocked with
RA1
(run monitor relay).
Signals are input
when DC power
establishes
the rated voltage.
Start/Stop circuit
The stop switch turns off
by an emergency stop
or a stop caused by
exceeding a limit value.
