Contact service life: 2 000 000 cycles
Provided the application to be implemented requires fewer than 2 000 000 cycles, the PFH
) can be used in the calculation.
To increase the service life, sufficient spark suppression must be provided on all output
contacts. With capacitive loads, any power surges that occur must be noted. With DC con-
tactors, use flywheel diodes for spark suppression.
