How does Phase Sequence Relay works ? In this video, we explain how a Phase Sequence Relay works and why it is essential in protecting motors and industrial equipment. When power supply phases are accidentally swapped, motors can suddenly run in reverse. This is dangerous for applications like conveyors, pumps, and compressors where the motor must always rotate in the correct direction. We’ll cover: ✅ What is Phase Sequence and why it matters ✅ How motors behave without a Phase Sequence Relay ✅

The relay logic diagram consists of four rungs. Each rung contains various components such as normally open push buttons, relay coils (CR1 and CR2), normally open and normally closed contacts, solenoid coils (Sol 1 and Sol 2), and a 5/3 directional control valve connected to a cylinder. This setup facilitates the control of the cylinder’s movement using two buttons, a valve, and corresponding electrical components. #mechatronics #plcprogramming #programming #programmer #controlsengineering #auto
