In this article, what is a reed relay and nmp 69. How it works, in what areas this technology is currently used and its effectiveness. The functions of nmp 69 relays are explained in detail based on gerkon relays technology. Key words: nmp 69, reed relay, electromagnetic field, features and characteristics. Introduction In modern production technologies, reed relays are used in all market segments, including test and measurement equipment, medical electronics, telecommunications equipment, automation, security systems, and others. Consumption is growing, and the global production of reed relays cannot meet the growing demand for them. Being hermetically sealed, they can be used in almost any environmental conditions. Very simple in their design, they combine a variety of production technologies. A critical indicator of quality and reliability is tightness at the point of contact between the glass of the housing and the metal of the contact terminal. These materials must have exactly the same temperature coefficient of linear expansion. Otherwise, cracks and poor tightness of the flask may occur. Regardless of the sputtering or electroplating technology, the process of applying contact materials (usually rhodium or ruthenium) requires high precision and special cleanliness of the production facilities, similar in requirements to semiconductor production. Similar to the production of semiconductors, any foreign particles present during production will result in increased losses, quality and reliability of the products. external magnetic field . Issues such as the automation of transportation process control systems in the world, the introduction of systems implemented on the basis of microprocessor technologies in the continuous control of the state of train traffic control devices, the improvement of methods and technologies of control are taking one of the leading places. Therefore, in the process of ensuring security, it is necessary to introduce into practice diagnostic systems that increase the operational reliability of automation and telemechanics devices at railway stations, which are implemented on the basis of microelectronics technologies. In developed countries of the world, such as the United States, Germany, Japan, 164 ACADEMIC RESEARCH IN MODERN SCIENCE International scientific-online conference England, China and Spain, it is important to design and create railway automation and telemechanics systems, to ensure their stability, reliability and self-control, as well as to develop sophisticated microprocessor systems that give the necessary information about their technical condition. In this article, research on the implementation of NPM-69 block with the help of gerkon relay is carried out. The functional function of this block is to control and control the condition of the railway traffic lights on the road site, which are located at the entrance to the train and manyovr traffic lights. Let's consider the Compatibility scheme of the NPM-69 block (picture 1). The fourth scheme of the (BRRC) dialing group is the compliance scheme (SCH), which checks whether the steering rails are in the correct position and their actual position after the arrows are held. figure.1 Gerkon reley install instead of OP and PP reley with PVG in the NMP 69 block Figure. 1 can be seen from the picture, when the contacts of the OP Relay are in a current state, the Manba current goes to the PP relay through the NKN contacts, if the contacts of the PP Relay are in a current state, the train confirms that the traffic light relay is in a current state. Or the contacts of the PP relay in the non- toxic state confirm that the relay of the magnifying glass passes through the contacts of the KN relay in a non-toxic state. If the contacts of the OP relay sine are in a non-toxic state, then the Manba current through the contacts of the 165 ACADEMIC RESEARCH IN MODERN SCIENCE International scientific-online conference relays with the VK or VKM button, the electric chain of the comparison scheme goes to the minus library Relay unit NPM-69-M is a specialized electrical product for completing railway electrical circuits. It is available in several modifications, differing in the number of relays included in the relay and the mounting scheme. It is characterized by an increased service life, compact design and ease of maintenance. The unit is powered by a DC source with a rated voltage of 24.0 V. Relay units of NPM-69-M type provide route dialing in modular railway systems of electrical interlocking of control of actuators.Device and operation The device consists of a mounting plate on which relays and auxiliary components are fixed.The top of the device is closed with a transparent plastic cover.
