Product life of relay contacts
The standard life of the contact used for conductive AC loads, such as contactors and solenoid valves, is
500,000 times at 20 VA.
The following table shows the approximate life of the relay based on the results of our life test.
Test condition: 1 sec. ON / 1 sec.OFF

Introduction
35 VA
If rush overcurrent is shut off even under the above condition, the life of the relay contact is considerably
decreased.
Transistor output (sink type)
The output numbers in the table indicate the main unit terminal numbers. "Y010 or more" means the numbers
from Y010 to the largest number that the main unit has.
(The output numbers of FX3U-16MT/ S are Y000 to Y007.)
