Example
} Inductive load: 0,2 A
} Utilisation category: AC15
} Contact service life: 1,000,000 cycles
Provided the application requires fewer than 1,000,000 cycles, the PFH value (see techni-
cal details) 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 contac-
tors, use freewheel diodes for spark suppression.
We recommend you use semiconductor outputs to switch 24 VDC loads.
