Comparison of Logo Siemens and Zelio Logic Schneider Electric programmable relays

In the modern era of high technology, it is not at all surprising that some of the production and control processes in many enterprises are fully automated. To implement the process of automation, there are a huge number of complex mechanisms and clever devices, a small part of which are small devices called programmable relays.

The scope of their application is very wide, but most often they are in the service of enterprises, where it is necessary to logically control incoming signals, in other words, to coordinate the actions of electrical equipment. In turn, such electrical equipment can be small machines and devices, electric motors, lighting systems, devices for maintaining the level of humidity in the air, etc.

There are quite a number of programmable relays on the market today. But due to their functionality, they are significantly superior to other relays Logo Siemens and Zelio Logic Schneider Electric. Their principle of action is identical.The external qualities of both relays have undergone significant changes compared to previous models.

As for the technical characteristics of the presented models, they have the same number of digital and analog inputs / outputs (depending on the model, products with the Siemens logo have several types of programmable relays), they have LCD displays with a keyboard, which makes it possible to creating schemes not only using a computer, but also directly.

They have the same programming technology, as well as the types of logic elements on the basis of which control circuits are built (triggers, counters, the simplest logic gates AND, OR, NOR, XOR).

But despite the above similarities, programmable relays have differences. It makes no sense to consider those of them that refer to the design, color, shape, because the buyer is more interested in the technical characteristics.

Zelio Logic Schneider Electric Programmable Relay

Relay Siemens Logo has a slightly different programming language than Schneider Electric's Zelio Logic (which also has two). But an ordinary user can be calm - this practically did not affect the principles and basics of programming. The changes only affect interactions with computer models and the type of operating system installed.

But the Siemens logo has a distinct advantage. The program is completely Russified, and this is sometimes the main criterion for those who do not have programming as their main profession.

The number of programmable elements in the programs is slightly different Zelio Logic Schneider Electric — 160 rows, each row has five contacts and one coil, the Siemens Siemens relay can perform up to 200 functions in a program.

The Siemens Logo programmable relay has the possibility to additionally connect a text display with the following characteristics:

— 4 lines of 12 or 24 characters each;

— Support for 9 languages, including Russian;

— Construction of bar charts;

— Degree of protection of the front panel IP65;

— Connecting cable included in delivery.

At the same time, the Zelio Logic Schneider Electric LCD display has a large screen that can accommodate 18×5 letters. An important feature of Logo Siemens is the possibility of remote programming, which Zelio Logic Schneider Electric cannot boast of.

The application sector of these relays is exactly the same, since they are not highly directional relays. They are used in the industrial, administrative and economic sectors. Due to their high cost, these relays are not recommended to be used to perform relatively small logic operations.
