Dažnio keitiklių paaiškinimas: jų vaidmuo HMI ir PLC sistemose

If you’ve ever been to a factory, you may have noticed some odd boxes that make a buzzing noise. These boxes are known as frequency converters. They are key to making machines run better and faster. Let’s take a look at what frequency converters are, and their functionality in factories.

What are Frequency Converters?

A frequency converter is a particular sort of electronic circuit that can convert electric power at one frequency to the power of anotherhmi ls frequency. The electricity that makes machines go is like a river with flow at different speeds. In factories, frequency converters regulatehmi elements the speed of machines, conserve energy, and provide smooth, safe operation.

Why Are Frequency Converters Important?

Automation is the catch-all term to describe how machines and computers exert control over processes in factories. Back in the day,hmi machine machines were operated by people which was time-consuming and laborious. In the current day and age, thanks to automation, machines can function independently. This allows the work to be much more efficient and safer for all parties involved.

Two main systems concerning frequency converters are HMI and PLC. The person-machine interface system (HMI) facilitates human communication through screens that convey information and buttons to press to control devices. It’s like speaking to a machine in a language it knows. The other one is the PLC system, a kind of brain for the machines. It relies on programmed instructions on how the machines run.
