Data transfer unit is abbreviated as DTU, is a wireless data acquisition device specially used to convert serial port data to IP data or convert IP data to serial port data. It is transmitted through a wireless communication network. Today we are going to carry ou wireless control, between computer and varible frequency drive via to different model of DTU. This is varible frequency drive.

Three-phase unbalance refers to the inconsistency of the three-phase current (or voltage) amplitudes in the power system, and the amplitude difference exceeds the specified range. Due to the unbalanced load added by each phase power supply, it belongs to the fundamental wave load configuration problem. The occurrence of three-phase unbalance is related to the user's load characteristics, as well as the planning and load distribution of the power system. This article will introduce the method to solve the three-phase unbalance.

A laser machine is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". This article will introduce the structure of laser machine.

In addition to panel control and terminal control, we can also use the RS485 interface (Modbus RTU protocol) for remote control of ATO’s variable frequency drives. RS485 interface is quite useful for the centralized control and monitoring of equipment. This type of control plays an indispensable part in automatic industrial control. That's why we write this blog to illustrate how we can use the Modbus RTU protocol to control the VFD.

Can a three-phase 220V-240V motor work with a single-phase 220V supply? ATO single-phase VFD can do it. It can convert 1-phase 220V-240V into 3-phase to supply power to a three-phase motor, and can also reduce the inrush current when the motor starts.

Magnetic stirrers are very important in the laboratory and can be used to stir liquids or solid-liquid mixtures. Today we will introduce its characters compared with electric stirrers, and its own features and functions. We hope that after reading this article, you can know the features of magnetic stirrer.

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.

Butterfly valves are widely used, so the selection and purchase of butterfly valves is particularly important. Today, we will introduce the selection of butterfly valves so that you can buy a butterfly valve suitable for you. The plate of the butterfly valve is installed in the diameter direction of the pipeline. The butterfly valve is simple in structure, small in size and light in weight. It only consists of a few parts, and it can be opened and closed quickly by rotating 90°, and the operation is simple.

The gyroscope sensor is an easy-to-use control system for free-space movement and gesture-based positioning. It was originally applied to helicopter models, and has now been widely used in mobile portable devices such as mobile phones. Since the gyroscope sensor is so important, today we are going to introduce what is a gyroscope sensor to you. We hope that you can have a general idea about its work principle, characteristics and applications after reading.

A DC to DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low (small batteries) to very high (high-voltage power transmission). This is ATO DC-DC converter.

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.

There are three main methods of connecting fiber optics, each with its own advantages and disadvantages. And different methods of connection have different precautions, so make sure you understand the characteristics of each method and choose the one that works best for you. This time, we will show you how to connect and measure optical fibers.

ATO relay module adopts high-current relay (1NO+1NC or 2NO+2NC), available with 2 to 32 channel, LED indicator for working status, standard DIN rail mounting, widely used for all MCU control, industrial automation, PLC control, smart home control. 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.

A welding fume extractor is the equipment to use to remove welding fume created when working with metals used in welding applications. Metal fume created during the welding process is carcinogenic and can have dangerous long term effects if not properly removed from the breathing zone. Welding fumes are dangerous to all employees on the shop floor.

A power line filter, also known as EMI/ RFI power line filter, is an electronic passive device which is installed between the power line and the equipment in order to suppress electromagnetic interference (EMI) or radio frequency interference (RFI). Due to high attenuation performance, 1-phase and 3-phase EMI AC power line filters on ATO.com are good solutions for EMI suppression, which provide a reliable protection for a wide range of applications in the industrial areas.

A linear actuator is an electric drive device that converts the rotational movement of the motor into the linear reciprocating movement of the pushrod. It can be used as an executive machine in various simple or complex technological processes to realize remote control, centralized control or automatic control.

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.
