Relay Logic Controller (RLC) – Fundamentals to Applications
Course Overview:
This course provides a comprehensive introduction to Relay Logic Controllers (RLCs) — the foundation of industrial automation before the rise of PLCs. You will learn how electromechanical relays are used to create control circuits, design logic-based operations, and implement automated tasks without microprocessors.
The course bridges theory and hands-on practice, making it ideal for beginners, technicians, electricians, and engineers who want to strengthen their basic industrial control knowledge.
Course Objectives:
By the end of this course, learners will be able to:
Understand the principles of Relay Logic Control.
Read and create Relay Logic Diagrams (RLDs).
Design basic to complex control circuits using relays, timers, and switches.
Troubleshoot relay control circuits efficiently.
Compare Relay Logic and Programmable Logic Controllers (PLCs) for automation tasks.
Key Topics Covered:
Introduction to Relays and Contactors
Symbols and Standards for Relay Logic Diagrams
Basic Control Circuits: Start/Stop, Interlocking, Latching Circuits
Designing Sequential Control Systems
Use of Timers, Counters, and Overload Relays
Troubleshooting and Maintenance of Relay Systems
Safety Considerations in Relay-based Control Panels
Transition from Relay Logic to PLC Systems
Course Format:
Lectures with visuals and examples
Hands-on workshops (designing and wiring circuits)
Assignments and mini-projects
Quizzes to test understanding after each module
Who Should Enroll:
Fresh engineering and diploma students (Electrical/Instrumentation/Automation)
Working technicians and electricians
Industry professionals shifting from manual operations to automated control
Hobbyists interested in learning automation basics
Prerequisites:
Basic knowledge of electricity and circuits
Ability to read simple electrical schematics (helpful but not mandatory)
Duration:
4 Weeks (flexible for crash course: 1 Week)
