Logical Controllers

PLC controller, or programmable logic controller, is designed to automate control processes in production plants and devices. It is used as an element of the control system for pumps, sensors, lighting, switches, pressure, fans. Learn more about our offer of controllers and choose the right solution for you.

They are made of the best quality materials, they are durable and reliable.

How do PLCs work?

PLC controllers consist of several elements. The heart of the controller is the CPU, or central processing unit. It is the CPU that monitors analog or digital inputs, collects information from them and handles the output logic. The power module converts available power into direct current, which is supplied to the central processing unit and the input/output module. The input and output module receives the signal and, through the programming environment, converts it into a set action.

What does this mean? When, for example, the appropriate button is turned on, the module will transmit a signal to turn on a specific valve, relay or lighting. The CPU module of logic controllers is equipped with ROM and RAM memory. They contain the operating system, applications, drivers, and store data. Thanks to this, the drivers can be freely programmed. The controller must also have a communication module. It is the communication module that connects the device to the computer.

Programmable Logic Controller – Division

Compact and modular controllers are distinguished by their construction. What is the difference between them and what functions do they have? Compact controllers are smaller and are mainly used in simple devices and installations. A single housing of a compact PLC controller contains a power supply, CPU and a small number of digital outputs and inputs. Analog inputs and outputs are usually not used in them. You cannot expand this type of controller with additional modules.

Modular controllers, on the other hand, allow you to freely configure and expand the set of controller configurations. This type of PLC controllers has a separate power supply and processor, to which you can attach a number of modules. If necessary, you can freely connect and modify the controller, expanding it with additional functions to adapt it to the machines and devices being programmed.

PLC controller – what are its advantages?

What advantage does a PLC controller have over systems? PLC controllers are a solution that will give you great freedom and convenience during use. You can use the program that supports the controller many times by copying. There is no need for separate programming for each controller, which significantly shortens the work.

Modern controllers can be programmed remotely, thanks to the connection to the Internet. When changing the control, you do not have to replace the wiring, as is the case with contactor-relay systems. Diagnostics of machines with logic controllers is easier. You can perform all diagnostics from the controller level.
