Relays consist of two parts that are completely independent from each other. The first part, which is actually the relay coil, which can exist independently of the relay base or in a compact form, and the second part of the relay, which is the same as the relay base.\r\n\r\nToday, relays are widely used in the industry, relays are mostly used in control circuits, almost all devices used in the industry, either openly or covertly, use relays. is One of the advantages of the relay is that by using it, you can get a high power output with a very low power. In other words, it can be said that the relay is also considered as an amplifier because the input with low current and the output with high current can be received from it. Depending on the type of construction, relays have 2 bases for feeding the coil and one or more COM blades (common), one or more closed blades (NC) and one or more open blades (NO).\r\n\r\n One of the important applications of relays can be in using the PLC output path. Because the PLC outputs that exist as relays inside the CPU, it is possible that if they are directly connected to the consumer, they will be defective due to current draw. As a result, the output of the PLC is connected to the coil of an external relay and the consumer is stimulated by the blades of the external relay. The good thing about this is that if something happens to the consumer, the external relay is damaged, in which case the relay can be easily replaced, but if the PLC\'s internal relay is faulty, it cannot be repaired easily.\r\n\r\n## Parts of the relay:\r\n\r\nspring\r\nCoil to magnetize the blades\r\nContact blades\r\niron core\r\nNote) Relays used to be mostly made electromechanically, but today, with the advancement of technology, electronic relays, including SSR relays, etc., have also been made.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n**[Click here to view Kaken products.](https://www.automation24.ir/product/list/search/?manufacturer_id=6&pageItems=120)**\r\n\r\n## Things to know when buying a relay:\r\n\r\nRelay coil excitation voltage and current\r\nTolerable voltage of contacts\r\nThe number of blades\r\nAppearance of the relay

Internal shaft with a diameter of 12 mm\r\n3. Easy installation in small space\r\n4. Easy rotation with minimum force\r\n5. Supply voltage: ±5% D 12-24 VDC \r\n6. Diversity in the type of output\r\n\r\nThe shaft encoder converts the angular movement of a shaft or axis into countable electrical pulses. Encoders are divided into two types, incremental and absolute, in terms of performance.\r\n\r\n### Incremental encoder\r\n\r\nIn this type of encoders, a pair of transmitter and receiver LEDs and a calibrated disc (black and white or perforated) are used, and the calibrated disc is placed between the transmitter and receiver sensor. During the rotation of the graduated disc, the signal between the transmitter and the receiver is cut off and connected successively, and we will have a set of pulses at the output. By counting the number of pulses, the amount of rotation and displacement can be calculated.\r\n\r\nThe more the number of pulses, the more accurate the movement calculation will be.\r\n\r\nBy counting the number of encoder pulses, the amount of movement or rotation of the shaft can be measured. But if we have a row of output pulses, it is not possible to detect the direction of rotation. Therefore, the encoders must have a second set of pulses, which is separate from the primary pulse.\r\n\r\n\r\nAlso, a single pulse that represents the rotation time of a complete cycle of the encoder shaft is also produced by the encoders. The first set of pulses is known as A, the second set is known as B pulse, and the third unit pulse is known as Z pulse. \r\n\r\nIf there is a set of pulse A before pulse B, the encoder rotates clockwise (clockwise), and if pulse B is earlier than pulse A, the shaft rotates counterclockwise (clockwise).\r\n\r\nEncoders are made to produce different number of signals according to usage needs. The most widely used rotary encoder is Atonix in 3 signal and 6 signal types. In the three-signal model, the supply voltage is 24V DC and the encoder has 3 wires. In model 6, the power supply voltage signal of the encoder is 5V DC and the encoder has three pulses *A, *B, and *C in addition to the pulses A, B, and Z, which are exactly the opposite of the primary pulses. That is, when pulse A is at logic level 1, signal *A is at point zero level.\r\n\r\n### Absolute encoder\r\n\r\nA major problem in incremental encoders is that the count of pulses must be stored in a counter, and if there is a malfunction in the counter for any reason, the encoder loses its position. In the incremental encoder, the zero point of movement will not be clear. To solve this problem, absolute encoders were created that will always know the position they are in and the distance from the starting point (zero point). The disk used in these encoders consists of a number of equivalent grooves, which generate specific codes by rotating them.\r\n\r\nFor example, if the encoder has 3 sets of disks, we will have a 3-bit output, and as a result, the encoder is able to detect 8 locations.

Before contactors were made, connections were made by manual switches, which were of different types of blades, tongues and rollers, but with the arrival of contactors in the market, almost all the uses of simple switches Out of class, contactors were considered faster and more reliable.\r\n\r\n## Compared to simple keys, the contactor has characteristics such as:\r\n \r\n1. Command from several points \r\n2. Remote control \r\n3. Being economical \r\n4. Automatic shutdown in case of power failure \r\n5. The possibility of designing automatic circuits \r\n\r\n\r\n### contactor building:\r\n\r\nIt can be said simply that the contactors are a series of metal contacts that are insulated from each other and also made of a bobbin to attract and repel these contacts.\r\n\r\n\r\n\r\n\r\n**[Click here to view LS products.](https://www.automation24.ir/product/list/search?keywords=&in_description=1&category_id=0&inc_subs=1&manufacturer_id=24&pfrom=&pto=)**\r\n\r\n\r\n### Principles of contactor work:\r\n\r\nWhen the fixed bobbin is electrified by the control key, it acquires magnetic properties and attracts the moving part of the core like a magnet, since there are contacts in the attraction area that are in charge of turning off and on the electricity, when The attraction of the two cores of these contacts is connected and the contactor is connected.\r\n\r\nThere are springs between the two cores. The application of these springs is when the contactor is disconnected, so that when the coil is not fed by the control circuit, the electricity is cut off and the spring separates the two cores from each other.\r\n\r\n## Some important specifications listed on the contactor plate:\r\n \r\n1. Rated working voltage (ue): It is the voltage that the contacts can withstand with the rated current Ie.\r\n2. Nominal insulation voltage (ui): specifies the insulation strength between connecting members.\r\n3. Nominal supply voltage (uc): It is the amount of voltage that must be given to the contactor coil to trigger the contactor, and its value is usually written on the contactor.\r\n4. Rated working current (Ie): The rated working current of a contactor is a current that expresses the condition of using the contactor and is related to the type and amount of voltage.\r\n\r\n\r\n## Items that must be observed when buying a contactor:\r\n\r\n1.

Transformers are available in various types according to their applications, which include general-purpose transformers and special-purpose transformers. Transformers that are used in most electrical systems and are not designed for a special purpose are called general purpose transformers. which includes dry and oil transformers here. Transformers designed for a special purpose are called special purpose transformers. \r\n\r\nwhich includes: auto trans, trans measurement, trans scat and level balance, trans test. It should be mentioned that transformers with special applications, such as measuring transformers, have separate base names.\r\n\r\n### The basis of CT work:\r\n\r\nLike all transformers, CT is composed of two primary and secondary coils. The primary coil has a wire with a large cross-sectional area and fewer turns due to the high current, and on the other hand, the secondary coil has a wire with a small cross-sectional area due to the low current. And the number of turns that is connected to the ammeter is high. If we assume that a current of 1000 amperes enters one turn of the primary coil, then we will have a current of 1 ampere for every 1000 turns of the coil in the secondary. So we see that the current of 1000 amperes which could not be measured became one ampere which can be easily measured with a normal ammeter. Therefore, in this example, if we see a current of 1 amp on the ammeter, it means that our real current is 1000 amps, and if we see 1.5 amps, it means that our real current is 1500 amps. It was a better article, but usually in CTs, this ratio is 1000/5. Another point is that the CT is placed in series in the circuit.\r\n\r\n\r\n**[Click here to view Harris products.](https://www.automation24.ir/product/list/search?keywords=&in_description=1&category_id=0&inc_subs=1&manufacturer_id=66&pfrom=&pto=)**\r\n\r\n## Current transformers are divided into two types in terms of the core:\r\n1- Current transformers with measuring core\r\n2- Current transformers with protective core\r\n\r\n1- Current transformers with measuring core have the duty to be accurate within the nominal and normal current of the network. And these types of cores should go to saturation in short connecting currents and prevent the increase of current in the secondary and as a result preventing the burning and damage of measuring devices on the secondary side.\r\n2- Current transformers with protective core:\r\nThey should be able to be careful even in short circuit currents and reach saturation later so that they can show it in the secondary in proportion to the increase in the current in the primary, and by detecting this excess current in the secondary by the protection relays, they will cut off the command.
