0.005s
goes from OFF to start.
(Note that the ON-OFF status changes when the
designated time has elapsed during the execution of
the program.)
0.05s

0.1s
turned ON or a CPU module reset is performed,
goes from OFF to start.
(Note that the ON-OFF status changes when the

designated time has elapsed during the execution of
the program.)

• This relay alternates between ON and OFF at
intervals of the time (unit: s) specified in SD414.
• When Programmable Controller power supply is
turned ON or a CPU module reset is performed,
ns goes from OFF to start.
