What is the difference between 2U industrial control chassis and 4U industrial control chassis?

Industrial computers are all based on U, and U all represent the height standard of the industrial computer chassis. The standard height of 1U is 1.75 inches, which is 4.445 cm. Usually there are 1U, 2U, 4U, these kinds of standard industrial computer. The height difference between the 2U industrial computer chassis and the 4U industrial computer chassis is 2U, which is about 8.89 cm.

What is a 4U chassis?

A 4U chassis is an industrial control chassis. All server chassis have the same length and width. A 1U chassis means that the chassis needs to occupy one cell above the rack. 4U is 4 cells, which is 4 times the thickness of a 1U chassis.

U is a unit that represents the external size of the server, and is an abbreviation for unit. The detailed size is determined by the American Electronics Industry Association, which is an industry group. The specified dimensions are the width and height of the server. Racks that meet this requirement are sometimes referred to as "19-inch racks" because they are 19 inches wide. The thickness is based on 4 and 445cm

The size of the cabinet where the industrial computer is placed also adopts this general industrial standard. Usually 22U to 42U. A 1U height, removable sliding bracket is also installed in the cabinet. Users can flexibly adjust the height according to the elevation of the industrial computer to store 1U industrial control server chassis, industrial control chassis, and hub equipment.

2U industrial control chassis v.s.4U industrial control chassis

Compared with the 4U industrial computer chassis, the 2U chassis is much smaller and looks better. At the same time, the space occupied by the 2U chassis is relatively small, so the cost of hosting is low, while the 4U chassis occupies a large space, so the cost of hosting is higher. The tower type is more expensive, but its heat dissipation is good.

The 4U industrial computer chassis has a large space, many air holes, and the exhaust fan that can be installed is more optional, and the heat dissipation is much better than that of the 2U chassis with relatively small space. If the temperature is too high, it will easily affect the performance of the chassis. Therefore, when choosing industrial control chassis and server chassis, the fan heat of the chassis is also a very important reference condition.

When you need to add more things to the case, only a 4U case can hold it.

4U IPCs are generally used in harsh environments such as dust, smoke, high temperature, low temperature, humidity, vibration, and corrosion. As a result, the requirements for 4U IPC chassis are more stringent, and they must be more practical in a variety of harsh environments. Make sure that all accessories in the 4U IPC chassis can work normally.

Therefore, when purchasing 2U industrial computer chassis and 4U industrial computer chassis or server chassis, you should comprehensively consider various factors, as well as the additional costs that will be brought after purchase. Choose the 2U chassis or 4U chassis that best suits you.
