Instrumentation & Control Engineering - Understanding of Logic Diagram (Part - 12M2)

A logic diagram is a graphical tool used to represent how a control system or safety system responds to specific inputs (like sensors, switches) to produce outputs (like alarms, trips, or motor starts). It is essential in instrumentation, automation, and electrical systems for designing, troubleshooting, and understanding control logic. Purpose of a Logic Diagram 1. Define the logical relationship between process conditions and control actions 2. Show how inputs are combined using logic gates (AND, OR, NOT) to control outputs 3. Used in PLC/DCS programming, safety shutdown systems, and automation logic Join this channel Membership to get access to perks: https://www.youtube.com/channel/UCtltPE0BZcU9QKrMyxdph4A/join Note: Keep watching our channel eFunda where we are creating videos related to Engineering and Project Topics and saved under separate play List. 1) Fundamentals https://www.youtube.com/playlist?list=PLLKo6f5HHKAdaT9ZgNsl3iO4i9qm05tTL 2) Project / Career https://www.youtube.com/playlist?list=PLLKo6f5HHKAcJ_NvjjUdmmjK-GIHF-fjo 3) Engineering https://www.youtube.com/playlist?list=PLLKo6f5HHKAfupB6q9S6a-RhBmNl2AMcb 4) Instrumentation & Control Engineering https://www.youtube.com/playlist?list=PLLKo6f5HHKAfCDQLRRC22u8flW7KFJjwF 5) Telecommunication Engineering https://www.youtube.com/playlist?list=PLLKo6f5HHKAf_rkZ-dexA3lwpHgOopPi_ 6) Procurement Engineering https://www.youtube.com/playlist?list=PLLKo6f5HHKAekFsAbWRAVQ6lClKU5b08x 7) Renewable Energy https://www.youtube.com/playlist?list=PLLKo6f5HHKAePEoCR3p7vrihnGpXFnfaS 8) Interview Questions https://www.youtube.com/playlist?list=PLLKo6f5HHKAcgaGl40RsVgWory_uZtZGN 9) Electrical Engineering https://www.youtube.com/playlist?list=PLLKo6f5HHKAc2nCUwAudvJyg5EoApK4yy 10) Mechanical Engineering https://www.youtube.com/playlist?list=PLLKo6f5HHKAcyb9d2ceBt9q9tFAZ5R9BH 11) Historical / Social https://www.youtube.com/playlist?list=PLLKo6f5HHKAfC0lYQKglDOfux9dRAjfrd Please follow us: eFunda Instagram – https://www.instagram.com/efundachannel/ Facebook - https://www.facebook.com/efundachannel/?ref=pages_you_manage Please LIKE, SHARE and SUBSCRIBE to our channel eFundachannel .
