Holding circuit in plc

NettetSelf Holding Circuit (SHC) merupakan rangkaian yang dapat difungsikan sebagai rangkaian pengunci atau rangkaian Latch. Pada rangkaian Self Holding Circuit (SHC) sekali mendapat trigger maka output high (1) meskipun trigger tersebut dihilangkan (0). Sehingga fungsi self holding dapat mempertahankan kondisi output (1) secara konstan. NettetJesner v. Arab Bank, PLC, No. 16-499, 584 U.S. ___ (2024), was a case from the United States Supreme Court which addressed the issue of corporate liability under the Alien Tort Statute (ATS).

NettetThis problem can be solved by using timers. In this case we will use TON (ON Delay Timer). For explanation we consider one SWITCH for enabling the ON/OFF cycle and one lamp for output. When user presses the SWITCH then lamp will energize and remains ON for 5 seconds after that it will OFF for 5 seconds. This cycle will repeat itself.
