Switching of inductive loads (relays, contactors, starters, electromagnets, electric motors, etc.) with the help of any relay can cause an arc discharge when opening the contacts, which causes electromagnetic interference, which can lead to failures and damage to various electrical equipment.
Additional measures must be taken to reduce the level of electromagnetic interference to connect the inductive loads to the relay outputs of Atom devices. Some of the most common and effective solutions are shown below in Pic. 1 for alternating current and in Pic. 2 for direct current.
