| Abstract: | t is known that when the inductive load is opened, the electric arc may be produced between the contacts of relay. Its producing reason is theoretically expounded and the preventive measures to eliminate its production are proposed.In cider to increase the reliability of programmable controller the protection of its output contacts should be taken. |
