Pulse relay, the device assignment and connection diagrams

In recent years more and more popular way of gaining control lighting from several points. And to implement it as the most simple and cheap way to apply impulse relays. In this article you will learn about what the pulse relay, as well as consider the scheme of its connection.

Which requires pulse relay

Pulse relay (it is also bistable) has two normal position and intended to enable and disable the load on the control input signal with pitch. As soon as the control pulse disappears, the position of the contacts in the relay remains in an altered state again until it is stopped by a control pulse.

How does the relay

At the moment, there are only two types of these relays:

1. Electromechanical.

2. Electronic.

Structurally, the electromechanical relay is made from the following elements: a coil, a group of contacts, a system of levers and springs.

In large electromechanical impulse relays, modular contactors like except that voltage fed to them only at the moment of switching, i.e. the energy consumption is carried out only when switching.

The electronic switch is also present board with microcontroller and output electromagnetic relay.

Let's look at each type of impulse relays in more detail:

The principle of operation of electromechanical relays lies in the following:

In short a pulse coil which generates a magnetic flux. He, in turn, moves the bar with a fixed group of contacts, and a locking mechanism anchoring the bar in an altered state.

In order to better understand the principle of functioning of the relay, let's break it down into three blocks:

- The first block. Officer - contact group onaya serves as a circuit - breaking the electrical circuit.

- The second block. Intermediate - consists of a coil, the core and the movable armature.

- The third block. Control - in this type of electromagnetic relay box serves as a control, which is formed by the incoming electrical signal to the coil.

This type of relay has an extremely high reliability and durability.

Another kind of impulse relay is an electromagnetic relay:

This type of relay is responsible for the work of the microcontroller, is either a coil or a semiconductor switch as an intermediate unit.

Electromagnetic pulse relay is extremely sensitive to all sorts of different voltage drops and interference in the network, as there is a limit on the length of the dial-up in this type of relay, but this product is quite possible to add, for example, a timer, which will set the time interval after which to light will be switched off without additional switching actions.

Scope and connecting circuit

As you probably guessed, these relays are mainly used in lighting, "smart home" for the implementation of the system.

So are widely used such as a relay type RIO-1 (relay pulse to illuminate the first type)

RIO Scheme-1 connection is as follows:

Now let's go over the circuit. Suppose that at the beginning of the lighting was turned off by pressing any pushbutton for a short time and the phase will go on terminal Y. As a result, this will trigger the relay closed contact (11-14) and the light will be turned on.

If we carry out the re-pressing the same button (or any other), then the phase will go back to the terminal pulse relay Y, which will lead to his deployment and contacts 11-14 will change their position - the light off.

But the lighting scheme using the pulse relay with a central control:

Here, when you press the ON button will turn the lights throughout the house, when you press off will not occur, and the light will turn off if you press the OFF button.

Most of these switches are installed at the entrance to the house, when you need to turn off the lights at once.

conclusion

That's all I wanted to tell you about the impulse relays. If the article was useful to you, then put his finger up and thank you for your attention.
