The principle of smart relay module analysis

The principle of smart relay module:

The intelligent relay module is the most basic unit module of the intelligent lighting control system. The name is based on the principle it adopts: the principle of the relay, that is, using weak electricity (usually 12V, 24V, 36V) to control strong electricity, strong electricity Controlling lighting fixtures and weak currents as a means of communication enable a variety of control methods.

The function of the smart relay module:

First, to achieve intelligent lighting control, intelligent relay module from the principle of analysis, the use of weak current control of strong electricity, weak communication can be expanded, in the traditional local control mode, can be extended to computer control, timing control, linkage control, automatic Logic control, wireless control, remote control, etc.

Second, improve energy efficiency. Using a variety of sensors, through the pre-set logic control, combined with the function of timing control, lighting fixtures in batches of management, so as to improve energy efficiency.

Third, improve management levels and reduce maintenance costs. The smart relay module converts traditional human-controlled lighting into intelligent management, improving the efficiency of managers, lowering the cost of manual operations, realizing cost-savings, and bringing about a certain return on investment.

Classification of smart relay modules:

We usually divide the intelligent relay module according to the number of circuits it connects to: 4, 8, 12; if you exceed this number of circuits, you can use the module to stack them flexibly. This does not affect the functionality. Because each module has a communication terminal, it can be connected.

According to the functional classification: ordinary type intelligent lighting module, magnetic holding type intelligent lighting module, current detection type intelligent lighting module; function is different, of course, the price is different, after all, depends on the different raw materials.

According to the power load classification: 10A intelligent lighting module, 16A intelligent lighting module; 20A intelligent lighting module; generally used is the latter three, 5A, after all, is relatively small.

Of course, there are also classified according to the module's size appearance, domestic and foreign manufacturers, bus types, etc. Here, we will not introduce them one by one. If the price is different, the price is very different depending on the function.

Wiring of smart relay module:

To understand the wiring of the smart relay module, you first need to understand the schematic system diagram, as follows:

The wiring of the module is divided into two types: the wiring of the weak end and the wiring of the strong end;

Weak terminal wiring: as shown below. Each smart relay module has bus terminals above it. In general, the wiring at the weak end is in accordance with the "bus type" wiring, which is what we commonly call: hand-in-hand. The bus mode generally uses two-core or four-core. Two of them are weak current modules, and the other two are the signal lines of the module (two cores are for weak currents, but also for signals).

Strong electric terminal wiring: strong electric wiring is relatively simple, generally two ports as a group, follow the "left into the right out, from top to bottom" principle, one end of the module into the line, one end of the module outlet (ie Wire to lighting fixtures)

Smart relay module installation:

All smart relay modules use standard 35mm rail mounting, as shown in the figure:

Smart relay module precautions:

1. Drawings designed in the drawings are only designed with a concept. Manufacturers who need to be instructed can deepen the design according to the drawings and the characteristics of the company's products;

2. The intelligent relay module is just the most basic driver unit composed of intelligent lighting control system. It needs to cooperate with the rest of the auxiliary system modules to realize the operation of the entire system.

3. Note that the number of smart relay modules on a bus should not exceed a certain number. In general, theoretically, there are 64 bus units.

4. Pay attention to the load condition of the power supply module, that is, the number of intelligent relay modules.

5. Pay attention to the load condition of the intelligent relay module. AC contactors can be used when the rated load is exceeded.

The Hydraulic Filter Element is used in the hydraulic system to filter out particulate debris and rubber impurities to ensure the cleanliness of the hydraulic system.

The Filter Element is for high pressure section, medium pressure section, oil return section and oil suction section.

In order to reduce the dimensions of the filter element and increase the filtration area, the filter layer is generally folded into a corrugated shape, and the layer is generally pleated below 20 mm.
