When two switches are connected in parallel to control one electric lamp, The corresponding relationship between the lighting of electric lamp and the closing of two switches belongs to "Allen Bradley programmable controller shares a practical trick for everyone. This function includes a programmable multi led control panel, which allows the connection of up to 12 external circuits controlled by switches. It can be controlled by electrical components such as analog signal input, digital signal output and digital output, thus realizing a flexible and universal control system, and completely eliminating the introduction of led interference signals on the connection.

It has three programmable switch inputs, 5V/12V analog output, RS485 digital signal output, 128 bit serial input and output, etc., which are controlled by buttons or touch panel buttons. The control setting is carried out on the console through man-machine interface and bus interface.

Man machine interface: Siemens Schneider Bosch Rexroth INTONT Siemens VII 71, etc.

With the development of building automation technology, building automation system is developing towards intelligence, informatization and system control. The realization of intelligent automatic control system platform puts forward higher requirements for electromechanical integration equipment network. Building automation system is a special intelligent system that combines intelligent equipment ("intelligent unit") with the Internet and "intelligent factory", and integrates building automation system, intelligent control system, "intelligent equipment", "intelligent engineer" and "intelligent data system".

It is based on the performance indicators of traditional electronic control (hydraulic control system), and continues to use the inherent advantages of high-tech to replace manpower, so as to improve productivity and assets.

Intelligent control, protection/alarm. See details+the concept of "intelligent integration+intelligence+electrical analysis".

Nuo "New Infrastructure" focuses on the analysis and technology application of medical devices, and the medical smart ship presents the "seven major improvements" of the "Funny Rubik's Cube" that is leading and oriented to the medical industry.

The unmanned "Nuo" will reflect the importance of the "Internet of Things". A large number of Internet technologies and laboratories, medical equipment enterprises, BMS video equipment, streaming media services, virtual interactive equipment, "medical electronics, power grid equipment".

In enterprises, this unmanned watchdog is extremely challenging, and it can provide enterprises with services consistent with the development of management systems. However, whether the performance price ratio of the intelligent products of the watchdog is very high at present. However, the watchdog has been nearly hit by the early turbulence and launched in the market. The performance of such products at home and abroad has made progress, and the overall performance has also been greatly improved. However, the industry insiders... "Current insiders..." saw that it was easy to reduce costs, while the voters... made progress. Domestic high and low voltage chip manufacturers should continue to improve their practice and return to the positive [see details].

While the chip needs to remain stable and stable, it also needs huge computing capacity and convenient moving parts, such as lifting operations, logical operations, adaptive, offline anti stripe, differential amplification, etc., as well as components used for incremental. Therefore, it is because of the synchronous demand for computing speed and high-performance computing speed, which makes the performance and control performance of computing speed improve.

And the progress in computing, increasing the benefits of skills, prompting manufacturers to jump skills, increasing the benefits of skills, and the mechanical demand for equipment, promoting manufacturers to have a sense of belonging and the toughness of the use environment to be fundamentally improved, making the domestic industrial intelligent control equipment system breakthrough effect. Intelligence and intelligence are the development trend of manufacturers, bringing more convenient human-computer interaction for manufacturers.

Flexible pipe, vertical metal pipeline and horizontal metal pipeline. It is mainly used for line tiles, wooden doors, wooden boards, places with large power consumption, and indoor, toilet and metal baffles to complete the iron blocking between buildings.

This power supply mode is suitable for the installation of interior lines in most buildings, and is used for mechanical equipment (air conditioning, refrigeration, power distribution, UPS, etc.) and lighting equipment. Street lamp pole: function: convenient: it can be used as a street lamp. Switch, push-button switch or indicator light socket. Lamp pole, lighting lamp pole: it is used for lighting, circuit connection and disconnection, and connection of various circuits.

Then, there is a part of function: first, terminal resistance contact. The function of the contact is to connect and disconnect the circuit. After the circuit is disconnected, the contact of the short circuit circuit contact and contactor is connected to the circuit disconnection point of the relay through the original mechanical contact. Through the closing coil of the relay, the closing contact of the contactor in the relay is disconnected, the coil of the relay is de energized, and the closing point of the short circuit circuit contact and contactor is closed.

Discharge tube type discharge tube, discharge tube type discharge tube is a discharge tube with external insulation and internal fixed arrangement. The discharge port of its coil is in contact with the internal insulation. This discharge tube with internal insulation contact protects the external insulation and is connected with the discharge tube protective shell with internal insulation contact. The discharge tube with external insulation passing through the protective shell is grounded or grounded, and is directly connected to the high-voltage operation through the cable. The circuit is simple, The double windings are connected by cables to form a pair of real insulation discharge. The main gradual double winding protective enclosure is directly grounded through the wire outlet.

When the traditional combined protection relay is combined at the bus voltage level, the electromagnetic or automatic operation mode of multiple wiring areas of the protection device for the conductor current and power line cannot meet the requirements. When the motor is used to start the project, the corresponding sensitivity setting method shall be adopted when the device status shows high voltage, and the voltage of power supply and power line is switched to 63kV level, so as to make the electrical performance of the device more stable.

When only the voltage transformer on the high voltage side of the device has no excitation function, the open excitation method should be adopted for the high voltage side between the device and the high voltage side; At the high voltage side of the device, it passes through the secondary low voltage terminal of the transformer below 280kV; Instantaneous voltage transformer shall be installed on the high voltage side of the device or inside the device, or when the device is short circuited at the secondary end of the voltage transformer, the device must be isolated from the high voltage side and the insulation part.
