Terminal blocks are an important component in the automation and control industry as they are used as connectors for electrical signals. They offer a reliable and convenient way to join signals when quick disconnects are inappropriate. The 1821216 terminal block is a popular model used in many user applications. This article will discuss the application field and working principle of 1821216 terminal blocks.

Application Field

The 1821216 terminal block is mainly used in control systems for commercial and industrial use. Its wide application range, covering all kinds of industrial control, power distribution, process control, and communication systems, makes it ideal for many automation and electrical projects. It is commonly used in systems such as UPS, solar inverters, DC-DC converters, variable speed drives, MCUs, GPU-based robots, PC-based controllers and PLCs.

The 1821216 model is also popularly used in general electrical network applications and robotic control systems. Its reliable and quick connect design makes it suitable for many electrical connections within the same or different levels. It can also be used to connect different systems such as motor control, digital signals, and analog signals. It can also be used in mixed-signal systems for everything from PLCs to digital I/O, communication, programmable logic, and more.

Working Principle

The 1821216 terminal blocks feature a two-bolt fastening style that ensures maximum safety and dependability. The terminal block is made up of two pieces of stamping copper sheet. The inner core is divided into columns to carry current or signals, while the outer core is used as a grounding layer to ensure strong electrical connection. When two pieces of copper sheet are put together, they form a self-locking combination.

The 1821216 terminal block supports two kinds of wiring methods. The first is single wiring, which is used when a single core is connected, while the second is dual wiring, which is used when two wires are connected together. The two methods ensure reliable electrical connections and make the product suitable for a wide range of applications. The terminal blocks also feature insulation plates that protect against short-circuiting when connecting different components.

In addition, the terminal block boasts a patented push-in technology that requires no tools for installation. This makes the installation process fast and extremely convenient. The product also has a degree of protection of IP67, which makes it both dustproof and waterproof.

The 1821216 terminal block is a reliable and easy to use product with a wide range of applications. Its dual wiring and insulation plates make it suitable for a variety of control systems in the industry. Its patented push-in system ensures fast installation and ensures a strong and reliable connection without the need for tools. With its high degree of protection, it stands out as one of the most popular models of terminal blocks used in the automation and control industry.
