PLC is a digital computer used for automation of electromechanical processes.
PLC can be programmed to perform a variety of tasks such as controlling machinery, processes, and more.
VFD is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the motor.
VFDs are commonly used in HVAC systems, conveyor belts, and other industrial applications to control motor speed and torque.
