4DB-R107-08

Terminal blocks are devices used for securing electrical loads, wires, and conductors. Barrier blocks are one type of terminal block and are used to create a physical barrier between power sources and other connected sections of a circuit. The 4DB-R107-08 is an example of a barrier block and this article will discuss the application field and working principle of this terminal block.The 4DB-R107-08 is a dual barrier terminal block, meaning it is composed of two terminal blocks connected together. It is designed for voltage control equipment, mid-size industrial controllers, and automation systems. It is also suitable for power control in a variety of applications, including motor control applications that require the use of relay contacts.The primary feature of the 4DB-R107-08 barrier block is its two-piece structure. It consists of a normally-open terminal that is connected to terminal 1 and a normally-closed terminal attached to terminal 2. This design helps isolate and protect the power supply from the load. Additionally, the two-piece structure facilitates convenient wiring and a versatile arrangement of components, making it ideal for various applications. The 4DB-R107-08 block is available in four different voltage and current ratings, so it is compatible with a variety of outputs.The 4DB-R107-08 barrier blocks are certified to UL and CSA standards, meaning they offer dependable performance and protection against shock and heat. It is constructed with a dustproof enclosure and a strong, lightweight body to protect the terminals from short circuits and other potential hazards.In operation, the 4DB-R107-08 functions similar to that of a relay control. When the wiring connected to the terminal is closed, the two barrier blocks form a connection allowing current to flow between terminals 1 and 2. This creates the necessary power supply for downstream components. When the switch connected to the terminal is opened, current will be blocked from flowing through the terminals, thus disconnecting the downstream components from the power supply.In conclusion, the 4DB-R107-08 is a dual-barrier terminal block designed for use in many different applications. It is UL and CSA certified and it features a two-piece structure that helps isolate and protect the power supply from the load. Additionally, it is available in four different voltage and current ratings and is easy to wire. In operation, it functions similar to that of a relay and when the switch connected to the terminal is open, it creates the necessary power supply and connection for downstream components.
