PLC Integrated Interlock System

Description: The PLC Integrated Interlock System is a programmable safety and control module that manages logical sequencing, interlocking, and safety shutdowns across critical equipment.
It ensures that pumps, valves, motors, and sensors operate in the correct sequence and that unsafe conditions automatically trigger alarms or system isolation.
The system combines the reliability of industrial PLC hardware with custom-configured logic for automation, safety, and compliance in fuel handling, chemical processing, and industrial control applications.
