Terminal Blocks - Barrier Blocks:Terminal blocks, also known as connectors, are connecting elements that are widely used in various automated systems and instrumentation applications. This article will discuss the application field and working principle of barrier blocks, one of the types of terminal blocks.Barrier blocks are specially designed for applications that require a large number of connection points from multiple power sources. They consist of a separate insulated conductor and pressure bar, and are connected to one another using solderless or impervious splices. This design allows for more secure connection points, which minimizes the risk of short-circuiting and other potential risks.In practice, barrier blocks are used in applications that involve power and signal connection between two or more circuits, such as between controller boards and relay controllers. They can also be used as power distribution blocks, or as signal input or output (I/O) connectors.The working principle of barrier blocks is actually quite simple. When two barriers are connected, the current travels from the negative voltage source through the connection bar and into the positive voltage source. This connection allows for both low voltage and high voltage connection points to be safely made, as any excess electricity is safely diverted away from the barrier block.Barrier blocks are also extremely useful for installations that require multiple power sources, as they provide a single, secure connection point for multiple systems. Additionally, they can be used as a safety device, as the different insulated barriers protect the components from short-circuiting. As a result, barrier blocks are often used in power distribution systems, motor control, and instrumentation systems.In conclusion, barrier blocks are a useful and versatile terminal block type, and are suitable for a wide range of automated systems and instrumentation applications. They feature a simple design that allows for safe and secure connection points, and provide a single, secure connection point for multiple systems. Therefore, they are a great choice for any system that requires multiple power source connections.
