Working principle of HMI touch screen
An HMI touchscreen works by detecting physical touch on the screen, converting that touch into digital coordinates, and then sending that information to a controller which translates it into commands to interact with the connected system, essentially acting as a visual interface for users to control and monitor a machine or process through a graphical display; this typically involves a touch sensor that detects the touch location, a controller to process the signal, and software to interpret the touch input and execute the corresponding action on the system.
- Touch detection:
The primary component is a touch sensor which can use various technologies like resistive, capacitive, or surface acoustic wave (SAW) to detect where a finger or stylus is touching the screen.
- Signal processing:
When a touch is detected, the sensor sends signals to a controller which processes the information to determine the exact coordinates of the touch on the screen.
- Communication with system:
The controller then sends this touch data to the connected system (like a PLC) through a communication protocol, allowing the system to react to the user’s input.
- Visual feedback:
The HMI screen displays relevant information like process variables, status indicators, and graphics to the user, providing visual feedback on the system’s operation.
- Industrial applications:
HMIs are specifically designed for industrial environments, with features like rugged construction, high brightness displays, and compatibility with harsh operating conditions.
- Integration with PLCs:HMIs often communicate directly with Programmable Logic Controllers (PLCs) to control and monitor industrial processes.

Chapter 4
Working principle of PLC independent power supply
A programmable logic controller (PLC) power supply’s working principle is to convert incoming alternating current (AC) line voltage to direct current (DC) and then use that DC voltage to power the PLC and its components:
Here are some details about how a PLC power supply works:
- Power supply
The power supply takes in AC line voltage and converts it to DC voltage. This process includes using a transformer to step down the line voltage, rectifying it to convert it to DC, and filtering it with capacitors.
- Backplane
The backplane is a base that all the other PLC components plug into. The power supply provides power to the components through the backplane, either through a bus system or by wiring each component individually.
- Power ratings
PLC power supplies come in different sizes and power ratings, depending on the PLC. Power supplies may be rated for 3 A, 4 A, 12 A, or 16 A.
- Battery backup
In addition to the main power supply, PLCs usually have a battery backup.
- Power for output modules
Output modules require higher currents, which are usually provided by external power sources.
PLCs can use both AC and DC power supplies, but they typically operate on DC voltage.

Chapter 5
Working principle of frequency converter
A frequency converter, also known as a variable frequency drive (VFD), changes the frequency of an alternating current (AC) to a different frequency and/or amplitude. It does this by converting the AC power to direct current (DC), filtering the DC, and then converting the DC back to AC.
Here are the main components of a frequency converter and how they work:
- Rectifier: Converts the AC input voltage to DC using a semiconductor bridge rectifier
- DC intermediate circuit: Filters and smooths the DC output from the rectifier to make it more stable
- Inverter: Uses semiconductor switching elements, like transistors, to convert the DC back to AC with a variable frequency
Frequency converters are often used to regulate the speed of motors that drive pumps and fans. They can also be used for:
- Testing products in foreign countries that use a different frequency
- Operating foreign equipment in a different country’s power grid
- In aircraft simulators
- Shore-to-ship services
- Avionics workshops
- Radar sites
Frequency converters have built-in safety features, like current sensors, voltage detectors, and thermal sensors, to prevent damage and unsafe working conditions.

Chapter 6
Working principle of soft starter
A soft starter works by gradually increasing the voltage supplied to an electric motor during startup, effectively limiting the initial inrush current and torque, allowing for a smooth acceleration instead of a sudden jolt, thus protecting the motor and connected machinery from damage; this is achieved by using solid-state switches like thyristors to control the voltage applied to the motor’s phases, essentially ramping up the power over time.
Key points about soft starter operation:
- Voltage control:
The primary function of a soft starter is to regulate the voltage supplied to the motor during startup, gradually increasing it from a reduced level to full operating voltage.
- Solid-state switches:
Typically, thyristors (silicon controlled rectifiers) are used as the switching elements within a soft starter, allowing for precise control over the applied voltage.
- Phase control:
Most soft starters control the voltage on all three phases of a three-phase motor to ensure balanced operation.
- Adjustable start profile:
Many soft starters allow users to customize the start-up profile, including the rate of voltage increase and the initial voltage level, to suit specific motor and application needs.
Benefits of using a soft starter:
- Reduced inrush current:
Minimizes the high initial current surge when a motor starts, protecting the power supply and electrical components.
- Extended motor life:
By reducing mechanical stress during startup, a soft starter can help prolong the lifespan of the motor.
- Improved operational smoothness:
Provides a smoother start-up for machinery, minimizing shock loads and vibrations.

Chapter 7
Working principle of servo drive
A servo drive’s working principle is based on a closed-loop control system that uses a feedback mechanism to maintain a motor’s operation within desired parameters. Here are the steps involved in how a servo drive works:
- Receive command
A servo drive receives a command signal from a control system, which can specify a desired velocity, torque, or position.
- Amplify signal
The servo drive amplifies the command signal.
- Transmit power
The servo drive sends an electric current to a servo motor to produce motion.
- Receive feedback
A sensor attached to the servo motor sends the motor’s actual status back to the servo drive.
- Compare and adjust
The servo drive compares the actual motor status with the commanded status, and then adjusts the voltage, frequency, or pulse width to the motor to correct for any deviation.
Servo drives are known for their high levels of precision and efficiency. They are commonly used in closed loop systems for precise position control in industrial and commercial applications.

Chapter 8
Working pinciple of Motor
A motor works based on the principle of electromagnetism, where a current flowing through a conductor placed within a magnetic field experiences a force, causing it to move, thus converting electrical energy into mechanical energy; essentially, when current passes through a coil of wire within a magnetic field, it creates an electromagnetic force that causes the coil to rotate, generating mechanical power.
Key points about motor operation:
- Electromagnetic Induction:
The fundamental principle behind motor operation is based on Faraday’s law of electromagnetic induction, which states that a changing magnetic field induces a voltage in a conductor.
- Magnetic Field Interaction:
When current flows through a coil of wire, it creates a magnetic field around it. This magnetic field interacts with the magnetic field produced by permanent magnets within the motor, causing a force that pushes or pulls on the coil, making it rotate.
- Commutator and Brushes:
In a DC motor, a commutator (a split ring) and brushes are used to reverse the current direction in the coil at the appropriate moment, ensuring continuous rotation.
- Torque Production:
The force generated by the interaction between the magnetic fields creates a torque, which is the rotational force applied to the motor shaft.

Chapter 9
Working principle of Contactor
A contactor is an electrical device that works by using an electromagnet to create a magnetic field that closes contacts to complete an electrical circuit. The working principle of a contactor is as follows:
- Current passes through the contactor
Current from an external control circuit passes through the contactor’s electromagnet, exciting it.
- Electromagnet creates a magnetic field
The electromagnet produces a magnetic field that attracts the contactor’s moving core.
- Contacts close
The moving core moves the armature, which closes the normally closed (NC) contact. This completes the circuit, allowing current to pass through to the load.
- Circuit opens
When the current is removed, the coil de-energizes, the magnetic field disappears, and the spring returns the core to its original position, opening the contacts.
Contactors are often used to control electric motors and lighting. They are designed to open and close very quickly to prevent damage from arcing that occurs when the contacts open or close. However, closing too quickly can cause contact bounce, which is when the contacts slam together and rebound, creating a secondary arc. This can also cause additional wear and open-close cycles.
