  • Page 20: Protective Wiring Of Relay Outputs

    Protective Wiring of Relay Outputs Protective Wiring of Relay Contacts Relay contacts are subjected to electrical erosion. Especially with inductive and capacitive loads, the service life of the contacts will be reduced. For suppression of sparks and arcing, components such as RC combinations, nonlinear resistors, series resistors and diodes should be used.
