Data transfer unit is suitable for many and scattered and complicated geographical environments. It can be connected to data terminals such as PLC, RTU, rain gauge, liquid level gauge, etc. Data transfer unit is widely used in power, environmental protection, LED information release, logistics, hydrology, meteorology and other industries. In the follow, the article will introduce remote transmission of data transfer unit.

This is because the structure of the inverter is AC-DC-AC. Whether single-phase 220V or three-phase 380V, the input AC power must first pass through a three phase rectifier bridge or a single-phase rectifier bridge to convert the AC power into DC power, and then use the point The capacitor filter is removed, and  it becomes a DC power supply with relatively flat ripples. Next, the three-phase bridge-type urinal controlled by the chip converts the DC power supply into a three-phase AC power supply whose frequency and voltage can be controlled arbitrarily.

A pressure sensor is a device that can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain law. It usually consists of a pressure-sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. ATO pressure sensor is the most commonly used sensor in the industry. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electricity, ships, machine tools, pipeline and many other industries.

A Digital counter is an LED control instrument, which can be used for distance measurement, packaging counting and position control. The input signal can be various waveform pulse signals and sensor signals. The input signal can be various waveform pulses and sensor signals, such as grating, proximity sensor, photoelectric sensor, contact switch, encoder, etc. (NPN, PNP). The digital counter can be directly connected to the computer and PLC. It is widely used in food, machinery, packaging and other industries.

VFD is generally a power control device that converts a power frequency power supply into another frequency by using the on-off function of power semiconductor devices. The main circuit of the variable frequency drive can be roughly divided into two categories: the voltage type is a frequency converter that converts the DC of the voltage source into an AC, the filter of the DC circuit is a capacitor; the current type is a frequency converter that converts the DC of the current source into an AC, its DC loop filter is inductance.The following ATO will introduce you how to set 120V to 220V VFD panel

The automatic holding circuit is often used in various electrical cabinets and is a simple logic circuit. Of course, this simple logic circuit can be built in a large number of PLCs, it is the basis of PLC logic instructions.

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.

Selecting the right butterfly valve requires a comprehensive consideration of factors such as media characteristics, pressure, and structure. Choosing the wrong specification can lead to frequent maintenance and costly system downtime.

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.
