Recommended replacement cycle for
FA-M3
■
Recommended replacement cycle: 10 years
However, modules that use parts with service life have the
following cycles.
●
Modules that use aluminium electrolytic capacitors: 8 years
●
Modules that use relays
Electrical life: 100 thousand cycles,
mechanical life: 20 million operations
●
Modules that use photocouplers: 5 years
When used in high temperatures (about 45°C or higher)
IMPORTANT
・
Recommended replacement cycle is a time period for preventive
maintenance of parts with service life, but is not a guarantee against random
failures.
・
Recommended replacement cycle is a guide, and varies with operating
conditions.
