Use Surge Suppressors
Because of the potentially high current surges that occur when switching inductive load devices,
such as motor starters and solenoids, we recommend the use of some type of surge suppression to
protect and extend the operating life of the controllers output contacts. Switching inductive
loads without surge suppression can
significantly reduce the life expectancy of relay contacts. By
adding a suppression device directly across the coil of an inductive device, you prolong the life of
the output or relay contacts. You also reduce the effects of voltage transients and electrical noise
from radiating into adjacent systems.
Refer to the Micro830/Micro850 Programmable Controllers User Manual, publication
, for suitable surge suppression methods and recommended surge suppressors.
