Introduction

Terminal blocks, also known as Din Rail, Channel or connecting systems, provides a secure attachment point on the digital industrial networks. Terminal blocks are mainly used to link different field terminal blocks (FTBs) to an automated system. They provide a safe abstraction of the connection between two FTBs when needed.

Application Field

Terminal blocks are used in a variety of industrial and domestic applications. In industrial settings, Terminal blocks are commonly used in electronic and process automation. They are a fundamental building block in modern automated systems. In addition, they are frequently used in controlling power distribution and providing electrical signal conduction pathways in industrial and engineering systems.In addition to its usage in industrial applications, Terminal blocks can also be used in residential settings. Residential usage mainly involves acting as a junction box for electrical circuits. With this application, various electrical circuits can be connected to give additional options and convenience. These junction boxes are mainly used to provide power and data connections to various household appliances and home automation systems.

Working Principle

Terminal blocks operate on the principle of providing a secure electrical connection between two FTBs. The terminal block provides a platform where wires can be effectively bundled and maintained in an organized manner and securely held in place.In addition to its primary function, the terminal block is also used to provide electrical signalling. This is done by connecting the FTBs in a series in order to provide a continuous electrical signal between devices. Each terminal block is fitted with conductor bars, which are bridged by metallic contacts. This ensures that the electrical current flows in the desired direction. The terminal blocks are also used to protect any electrical device from over voltages and over currents. This function is achieved by the use of fuse holders or surge protectors, which are embedded in the terminal blocks. Fuse holders are used to detect excessive electrical currents, which cause fuses to blow, thus providing protection to the connected devices. Surge protectors, on the other hand, detect a sudden increase in voltage, thus protecting electrical devices from damage.

Conclusion

In conclusion, the Terminal Blocks, also known as Din Rail, Channel or connecting systems, provide a secure form of electrical and power connection between two FTBs. They are used in both industrial and residential settings, providing safe abstraction of the connection between two FTBs. Terminal blocks work through the use of conductor bars and metallic contacts. They also provide protection against surges and over currents by the incorporated fuse holders and surge protectors.
