Terminal Blocks are a type of electronic component used to terminate electrical circuits, and come in a range of types including Din Rail, Channel, etc. In this article, we explore their application fields and working principles.

Din Rail Terminal Blocks

Din Rail terminal blocks are a type of terminal blocks consisting of two channels or strips that are pressed and released for connection or disconnection of power through electrical wires. As the name suggests, these two channels are mounted, secured and aligned to a DIN rail, and jointed to wires via screw nuts, bolts or other holding mechanisms. Din Rail terminal blocks are widely used in applications that require multiple power source connections. Common applications are buildings, HVAC systems, industrial control systems, basic automation, etc.

The working principle of Din Rail terminal blocks is quite simple. When the supplied electrical current is connected to the terminal, it gets distributed among the interconnected systems, provided they are correctly wired. This distribution of energy helps power a wide variety of applications and systems.

Channel Terminal Blocks

Another type of terminal block created to help with power distribution is a channel terminal block. These blocks come in two distinct variations, single channel or double channel blocks. Single channel terminal blocks have a single block connected to each other which is generally used for connecting one power source to the other. Whereas double channel blocks have two blocks connected which can easily join two different power/ electrical connections. As with all terminal blocks, channel terminal blocks are widely used to route power from a source to one or multiple loads.

The working principle of channel terminal blocks is also simple. Once a channel terminal block is wired, it establishes a secure connection between multiple power sources. Depending on the number of channels and the voltage or power supplied, each source can be connected, and provide a steady power output from the connected. This makes connecting power sources in an automated system convenient and simple.

Conclusion

Terminal blocks are an essential electronic component used in almost any automated system applications. From Din Rail terminals to channel terminals, they help establish secure connections between electrical circuits, and allow electrical to be routed from a source to other loads. No matter the application, it’s important to understand the type of terminal block being used for optimal results.
