Relays are an electronic control device with a control system (that is, an input loop) and a controlled system (output loop), and are usually used in automated control circuits. The relay is actually an "automatic switch" that uses a small current to control the operation of a large current. It plays the role of conversion circuit, automatic adjustment and safety protection in the circuit.

The transmitter is a device that converts physical measurement signals or ordinary electrical signals into standard electrical signals (4~20mA, 0~20mA, 1~5V, 0~ 10V, etc.) output or can be output by communication protocol (CANBUS, MODBUS, PROFIBUS, etc.) ATO offers high-performance current transmitters, level transmitters, voltage transmitters, temperature transmitters, load cell transmitters, pressure transmitters, temperature and humidity transmitters, and PH transmitters.

Blowers are equipment or devices which increase the velocity of air or gas when passed through equipped impellers. They are mainly used for flow of air/gas required for exhausting, aspirating, cooling, ventilating, conveying etc. Air blower machines are a simple and effective electrical device used in homes and industries to blow away dust from every nook and corner. For gadgets and electronics that have delicate parts that cannot be cleaned with a cloth, this is when you need air blowers to remove dust with its continuous air pressure. This durable and efficient machine saves a good amount of time and effort consumed in cleaning and dusting tasks.

An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. When a failure occurs in a primary power system, the ATS invokes a standby power source, such as an uninterruptable power supply. An ATS can also start up more long-term backup power systems, such as local diesel generators, to run electric equipment until utility power is restored.

Shunt means parallel. In simple words, the capacitor is connected in parallel with a load or power supply is called shunt capacitor. The series and parallel combination of a no. of shunt capacitors is called shunt capacitor bank. So shunt capacitor is not a special device. It is a normal capacitor only, it is called a shunt capacitor because of its parallel connection with the load. Shunt capacitors are used in transmission lines, power systems, with inductive loads. So AC or non-polarized capacitors are used as shunt capacitors. For DC circuits or DC applications polarized capacitors are used.

Laser is a major invention of the 20th century, known as "the fastest knife", "the most accurate ruler" and "the brightest light". The word "laser" is an acronym for "light amplification by stimulated emission of radiation", which describes the principles of how lasers are produced.

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.They can be used on any rotating object to transfer power, control circuits, or analog or digital signals including data such as those found on aerodrome beacons, rotating tanks, power shovels.

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.

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.

ATO time relay is a very important component in the electrical control system. In many control systems, time relays are required to implement time delay control. It is an automatic control electrical appliance that uses the principle of electromagnetic or mechanical action to delay the closing or breaking of contacts. Its characteristic is that there is a delay from the time when the attracting coil gets the signal to the action of the contact, which is generally used for the motor starting process control with time as a function.

Surge protection device, also known as SPD, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When a surge current or voltage is suddenly generated in an electrical circuit or communication line due to external interference, the surge protection device can conduct the shunt in a very short period of time, thereby avoiding the damage of the surge to other equipment in the circuit.

Pneumatic solenoid valves are electromechanical devices that control the flow of air or process gas. They are mostly used for controlling pneumatic actuators such as cylinders, turbines (pneumatic motors), diaphragms, and tubes. ATO.com online store provides a series of pneumatic solenoid valves to control the flow of air with internal pilot operated, including 2 way, 3 way, and 5 way.

ATO has 12V / 24V DC, 2 ~32 channel relay modules. These relay modules can save a lot of space occupied by traditional relays, which is the preferred alternative to traditional relays. Now, we will introduce an ATO 12 / 24V DC relay module.

The full name of RTD is Resistance Temperature Detector. RTD is a special kind of resistor whose resistance value increases as the temperature increases and decreases as the temperature decreases. RTD is used as sensor in industry to measure temperature, so RTD is also called "thermal resistance". RTDs are more linear than thermocouples and are the most accurate and stable temperature sensors available. But because the change of resistance takes time, its response speed is slow. At the same time, its price is relatively expensive, and it is suitable for occasions where there are certain requirements for accuracy and the cost control is not strict.

At present, with the continuous improvement of people's living, various industries pay more and more attention to the temperature and humidity management environment of product production, equipment and warehouse storage. Therefore, it is necessary to use the temperature data loggers. The temperature and humidity data logger measures the temperature and humidity parameters and stores them in the recorder according to predetermined time intervals or uploads them to the computer cloud platform through Bluetooth or USB. The data logger can be exported and analyzed to ensure that whether there are any incidents that endanger the safety of the product during the storage and shipping. However, which industries need temperature and humidity monitoring systems?

The full name of OTDR is Optical Time Domain Reflectometer. An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It is the optical equivalent of an electronic time domain reflectometer. OTDR is widely used in the maintenance and construction of optical cable lines, and can measure optical fiber length, optical fiber transmission attenuation, joint attenuation and fault location.

Hybrid stepper motor is a stepper motor designed by combining the advantages of permanent magnet and reactive. It is divided into 2 phase, 3 phase and 5 phase. The two phase stepping angle is generally 1.8 degrees, the three phase stepping angle is generally 1.2 degrees, and the five phase stepping angle is generally 0.72 degrees.

DIP switch, short for dual in-line package switch, is an electrical switch that can be turned by hand. Its pitch includes 2.54mm and 1.27mm. There are two pins on the back of each position, all on ON side, which is turned on, and then disconnect. These pins are independent and there is no association with each other. Such products are mostly used for binary coding.

A molded case circuit breaker, also known as an installation circuit breaker, is an electrical protection device used to protect a circuit from overcurrent, which can cause an overload or short circuit. All parts are sealed in plastic housing, auxiliary contacts, undervoltage releases and shunt releases are mostly modular. Due to its very compact structure, molded case circuit breakers are basically impossible to repair. Most of them use manual operation, and large-capacity can choose electric switching. Due to the application of electronic overcurrent release, molded case circuit breakers can also be divided into two types: class A and class B. Class B has good three-stage protection characteristics, but due to price factors, the use of thermal magnetic release Class A products have a higher market share.

Hall effect magnetic proximity sensor can achieve the largest detection distance with a small switch volume. It can detect magnetic objects (usually permanent magnets), and then generate a trigger switch signal output. Since the magnetic field can pass through many non-magnetic objects, this triggering process does not necessarily require the target object to be directly close to the sensing surface of the magnetic proximity switch, but the magnetic field is transmitted to a long distance through a magnetic conductor.
