Terminal Blocks - Barrier Blocks

0387012608 Application Field and Working Principle

Barrier blocks are used to connect multiple devices to a larger circuit in terms of both power and communication. This type of terminal block can, for example, be used to connect several power supplies to a larger bus system, as well as in distributed control systems for communications. Barrier blocks are designed to provide an easy and efficient way of connecting multiple devices to a larger circuit. The most common model uses a type of insulation barrier which is inserted between each pair of connections to prevent a direct electrical connection between them.Barrier blocks are available in a wide variety of sizes, shapes, materials and terminations, to meet various customer needs. The design of these barriers can range from basic terminal blocks, to more advanced models, depending on the application. In general, these terminal blocks have a metal or plastic body, and are either surface or DIN rail mounted. The front can feature pre-punched holes for the connection of wires, or solder blocks to allow for the connection of multiple devices.The working principle of a barrier block is relatively straightforward. Wires are connected to each individual terminal, with the insulation barrier between them providing an independent barrier between each circuit. As power is supplied to the individual blocks, the barrier prevents any electricity from moving between the two circuits, thus avoiding any potential circuit overload.Barrier blocks are also used extensively in industrial control systems, for the connection of multiple devices to a single circuit. By using multiple terminal blocks, one can create a “daisy chain” of devices, enabling the connection of multiple components, without the need for multiple wiring assignments. This allows for a quicker and more efficient system installation process, as well as a more reliable connection between all the devices. In addition, these types of blocks can also be used for parallel connections, with multiple blocks connecting multiple devices.The advantages of barrier blocks make them ideal for a wide variety of industrial applications. From powering multiple devices, to connecting multiple signals, to providing data communication between multiple devices, this type of terminal block offers a versatile and efficient way to connect multiple devices. As such, these blocks have become an essential component of industrial control systems, providing a reliable and efficient way to manage and control multiple devices.
