SCM-38I - RS-232/485 converter

19.11.2015

Digital signal conversion is widely used in industrial automation. RS232/RS485 converters are used to convert RS-232 interface signals to RS-485 interface signals during transmission and vice versa, for example, between a PLC and a personal computer or HMI panels.

RS-485 is a widely used interface in industrial networks due to reliable and at the same time cheap signal transmission between controllers and other microprocessor equipment over long distances (up to 1200 m without repeaters). RS-232 was originally used to exchange data between a personal computer and a modem at a distance of up to 15 m.

Autonics releases the SCM-38I converter designed for reliable conversion of RS232C to RS485 interface signals and vice versa.

Specifications:

Supply voltage - 12...24 V DC;
Switching speed 1200...115200 bps;
Type of communication - half-duplex;
Maximum distance - 800 m;
The number of plug-in modules - up to 32 pieces;
Connector on RS-232 side - D-SUB 9 connectors;
The connector on the RS-485 side is a 4-pin terminal with a screw fastening of wires.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Butterfly wings cooling 23.02.2020

In order to take off, a butterfly literally needs to warm up: if its muscles are not warm enough, they simply cannot contract at the speed that is needed for flight. Therefore, if the butterfly is too cold - for example, after a cold night - it crawls out into the sun and warms itself. But after all, not only her pectoral muscles are heated, but her whole body, and the wings too, and the wings heat up faster than the muscles. And it may happen that by the time the muscles are ready to take off as they should, the wings will be overheated.

Although the wings of butterflies seem to us inanimate - in the same sense in which bird feathers or our nails are inanimate - they still have areas of living tissue: these are the vessels penetrating the wing, through which the hemolymph (an analogue of blood in insects) flows, and the so-called androconia are groups of specialized scales that evaporate pheromones. Overheating for living areas of the wing would be inopportune. But butterflies have some tricks that allow them to cool their overheated wing.

Researchers from Columbia University, together with colleagues from other scientific centers, developed a special method with which it was possible to evaluate the heat radiation at different points of the butterfly's wing (a conventional infrared camera was not suitable here - it could not even distinguish the heat radiation of the wing from the heat radiation of the background). The new method was tested on 50 species of butterflies, and it turned out that the living areas of their wings are covered with special tubular nanostructures that serve as a kind of radiator; in addition, both vessels and odorous areas carry a thicker layer of chitin, which also helps to dissipate heat.

Some butterflies also showed an additional cooling system: for example, the male pigeons Satyrium caryaevorus and Parrhasius m-album have a vascular structure in their wings that pumps blood through odorous organs - these vessels contract several tens of times per minute. Such a pseudo heart in the wings makes them heavier, but the butterflies are apparently ready to put up with the extra heaviness in the wing, just to keep it from overheating and not letting their own source of pheromones deteriorate.
