Terminal Blocks - Barrier BlocksBarrier blocks are an important form of terminal blocks which is widely used in many industrial applications. The purpose of a barrier block is to break an electrical connection between two or more points, either in a permanent or temporary fashion. What is unique about these types of blocks is that instead of using set screw terminals, they utilize connection points that are physically covered by an insulating barrier, creating a physical divide separating the different points.Despite the name, barrier blocks are actually quite versatile and can be used to serve a number of different purposes. Some of the most common uses for these blocks are distribution of low voltage power, creation of signal lines, making devices easier to diagnose, and providing flexibility in device wiring and maintenance.In terms of application field, barrier blocks are most commonly used in industrial automation systems. These blocks are used in production lines where electrical signals and power need to be distributed across many different devices and controllers. They are also used to connect and separate devices within the equipment when necessary.In terms of working principle, barrier blocks use a simple but effective design. Physical barriers are placed in between the connection points to physically separate them. This can be done either through connectors with insulating material in between, or by utilizing small holes that are drilled through the body of the block. Each connection point is also provided with terminals for connecting wires and can be further secured by tightening screws.The advantage of using a barrier block is that it is much safer and easier to use in high voltage applications. The physical barriers provide an extra layer of safety as it prevents any short circuits from occurring. It also provides extra insulation in case of unexpected contact between the different terminals.Another benefit of using a barrier block is that it can be easily added to existing systems. It allows you to easily move components between devices without having to rewire anything. This makes it easier to do maintenance and setup as you don’t have to physically undo and redo connections every time.Overall, barrier blocks are a very useful and versatile form of terminal blocks. They are commonly used in industrial settings but can also be used in many other applications. They are simple to use and maintain, making them a great choice for many applications.
