Based on the “PLC digital input circuit”, continue to improve the input circuit. Specific requirements: 1. The S8-S13 devices are limit switches located outside the control cabinet, so selection is not performed at this time; 2. The diagram includes devices inside and outside the control cabinet, and it is required to label the connection terminals … Read more
Introduction **Hello everyone!** Today we are going to discuss a seemingly simple yet crucial aspect of automation control — the correct connection of PLC and limit switches.Don’t underestimate this small switch; it is the “eye” of automation equipment, directly affecting the reliability and safety of equipment operation.Red Alert: If connected improperly, it can lead to … Read more
