Interlocking in general is called protocol action. It means defined bunch action to be taken when certain conditions occur. In a view of PLC, Interlocking is an action that is defined in the PLC program to control the process when certain conditions occur f.e. temprature exceeding its limit, flow below requirement or any parameter exceeding beyond its safe operating limits.
Do you know how to program the PLC interlocking program? Follwing the steps below and you will program it quickly.

Load cell junction box is used for load cell, which has 2/3/4/6/8/10 inlets and 1 outlet, which is easy to assemble and debug. Each channel can be adjusted balance to prevent damage to the sensor caused by inductive lightning and surge signals. So let’s learn about how to test the load cell junction box with a digital panel meter.

Soft starter is a motor control device that integrates motor soft start, soft stop, light load energy saving and various protection functions. It not only realizes the smooth and shock-free starting of the motor in the whole starting process, but also adjusts the parameters in the starting process, such as current limit value and starting time, etc., according to the characteristics of the motor load. In the normal working state of the ATO soft starter, the motor runs normally after pressing RUN, and the bypass contactor is normally closed. Next let's setup the soft starter.

This blog shows that how does PLC control relay module.

The AC current sensor is a device for detecting AC current, which can sense the information of the AC current being measured, and can convert the detected and sensed information into electrical signals or other required forms of information output according to certain rules. It can meet the requirements of information transmission, processing, storage, display, recording and control, and is the primary link to realizing automatic detection and automatic control.

The heated magnetic stirrer is a laboratory instrument for liquid mixing, mainly used for stirring or simultaneously heating and stirring low-viscosity liquid or solid-liquid mixtures. The basic principle is to use the magnetic field of the same-sex repulsion and opposite-sex attraction principle, and use the magnetic field to push the magnetic stirrer placed in the container to rotate in a circle, so as to achieve the purpose of stirring the liquid. With the heating temperature control system, it can heat and control the sample temperature according to the specific experimental requirements, maintain the temperature conditions required by the experimental conditions, and ensure that the liquid mixing meets the experimental requirements.

The ball valve is a valve that uses a ball with a circular channel as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action. The opening and closing part of the ball valve is a ball with a hole, which rotates around the axis perpendicular to the channel, so as to achieve the purpose of opening and closing the channel. Ball valves are mainly used to open and close pipelines and equipment media.

3-phase induction motor is an electromechanical energy conversion device which converts 3-phase input electrical power into output mechanical power. 3-phase induction motor consists of a stator and a rotor.

The gas detector is used in the occasions where mobile fast detection and reading of various gas concentrations, temperature and humidity measurements on site, and alarms for exceeding the standard are required. The clear color screen is used to display the concentration in real time, and the electrochemical or infrared and catalytic combustion products that are the best in the current industry are selected. , thermal conductivity, PID photoion principle gas sensor, precision capacitive digital temperature and humidity sensor, simulation icon display menu function, pump suction measurement, built-in replaceable water vapor and dust filter, protection grade IP67, rain and short-circuit proof time to soak.

The vibration motor is an excitation source that combines the power source and the vibration source. A set of adjustable eccentric blocks are installed at each end of the rotor shaft, and the excitation force is obtained by the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block. The vibration motor has many advantages, including high utilization rate, low energy consumption, low noise and long service life. Next we will introduce how to use a DC vibration motor.

ATO offers a diverse range of spur gear motors, planetary gear motors and worm gear motors with power options falling between 30W and 2000W, voltage between 12V and 48V DC, torque between 0.1Nm and 300Nm, providing you with highly efficient gear motor solutions that can meet any application requirements.
What we have here today is a 30W DC gear motor that operates at 24V and 1 to 60 gear ratio.

The magnetic powder clutch is based on the electromagnetic principle and the use of magnetic powder to transmit torque. It has a linear relationship between the excitation current and the transmission torque. It can transmit a certain torque regardless of the slip. It has the advantages of pollution, no noise, no shock and vibration, energy saving, etc. Magnetic particle clutch is a multi-purpose and superior automatic control element. However, how to replace sealing ring of water-cooled magnetic powder clutch?

The digital panel meter displays the voltage, current value or other standard signal transmission display value in the electrical circuit by digital direct reading; the product has the advantages of good stability, strong anti-interference, high cost performance, and the product is small in size and can be directly replaced original pointer meter. It is widely used in voltage stabilizers, spot welding machines, calibration benches and various electrical equipment and control systems that have certain restrictions on the size of the instrument. Now we will introduce how to use a digital panel meter.

When we use a conventional contactor to control the rotation of a 3-phase motor, we usually need to exchange two of the three terminals to reverse the rotation.The output shaft rotates clockwise when L1, L2 & L3 are connected to U, V, W.

A single phase induction motor consists of a single phase winding on the stator and a cage winding on the rotor. When a 1 phase supply is connected to the stator winding, a pulsating magnetic field is produced. In the pulsating field, the rotor does not rotate due to inertia. The structure of the 1-phase motor determines that the reverse rotation is generally completed by hardware.

A garage door opener is a motorized device that opens and closes a garage door controlled by switches on the garage wall. It is common equipment in homes and factories. This article will introduce specific measures when garage door opener fails.

Optical fiber communication technology has developed rapidly in the last 20 years. Since optical fiber communication transmits a large amount of information at a fast speed, and it can transmits digital signals, which makes it possible to transmit information such as broadband image signals and computer networking. Thus, optical fiber measurement has entered into a new period of digitization.

Digital timer relay has the advantages of accurate measurement, simple setting, multiple protection functions and high speed, etc. It is an ideal substitute for traditional electromagnetic and static relays. Digital time relay is generally used in automation equipment electrical cabinet, street lamp control, water pump timing operation control, equipment timing start and stop control and other occasions. In this article, we will experiment to see how it is set up and works.

The position control mode of the servo motor is very common in the precision movement of industrial automation. The principle is that the servo motor drive carries out precise control of the motor movement after receiving the position pulse and direction pulse of the pulse generator (PLC, single chip microcomputer). Servo motor has three control modes: speed control, position control and torque control. This time we will introduce the position control mode of ATO new servo motor, using PLC to pulse.
