Terminal Blocks - Barrier Blocks

SEFX-9 is a specific type of terminal blocks, also called barrier blocks. It is typically used in industrial control applications, especially for isolated circuits. The block has several benefits, such as easy setup, simple isolation and reliable electrical contact.

In a barrier blocks system, the individual sections are typically bridged by a conductor which passes through a designated hole in the blocks themselves. This conductor can be a copper strip, a multi-core cable or even a single wire. There are also some models which feature slot connectors, and these can be used for both power and signal. In regards to physical structure, the blocks typically come in an extending U-shape.

The primary benefits of using SEFX-9 barrier blocks are the easy and hassle-free setup, even with inexperienced personnel. Moreover, their isolation is reliable due to their rigid construction. Additionally, since the block system provides an almost-complete electrical contact, the probability of arcing is much lower in comparison to a system using soft insulation. As a result, the user can rest assured that the risk of electric shocks and fires is much lower, so safety is increased.

In terms of its working principle, the SEFX-9 system follows a basic logic. At first, power is supplied to one end of the block, with common being connected to another and each other section taking on a separate outgoing power supply. Depending on the design, a separate signal might be supplied to each section. Then, the common power is used to power the internal connections, while each connected device is then directly powered through these connections. This allows for a much more efficient and dependable setup.

Overall, the SEFX-9 barrier blocks are a great choice for industrial control applications, due to their easy setup, reliable isolation and dependable electrical contact. Moreover, their working principle is much more efficient in comparison to a traditional insulation system. Thus, it is no surprise that the SEFX-9 has become such an important part of contemporary industrial control systems.
