Terminal Blocks - Barrier Blocks, as the name suggests, provide a barrier between two lines of conductors that are not meant to be connected. Generally, the application of these blocks is to provide a ‘firewall’ between two different systems, helping to prevent any accidental mismatching of the wiring.

The two components of a Barrier Block are a series of screws on one side, and a ‘jumper’ on the other side. The screws provide mechanical connection points for the lines that need to be separated, while the jumper bridges the gap and helps to eliminate any potential for inadvertently crossing the lines. This design also helps to provide good shielding against electro-magnetic interference.

Barrier blocks are commonly used in a variety of industries, including medical, automotive, manufacturing, and audio/video. They are often employed in applications that require a high level of safety, such as in pressure or temperature monitoring. Other applications include controlling power, data or communication links between two systems, and providing isolation for programmable logic controllers. In all cases, the Barrier Blocks are designed to eliminate the possibility of a short circuit or accidental crossing of the two separate lines.

In terms of their working principle, Barrier Blocks provide a type of circuit breaker. When two lines of conductors are connected, the resulting current flow may create a short circuit. This is where the Barrier Block comes in, providing a protective ‘firewall’ that guards against any potential short circuits. When the applied voltage exceeds a certain limit, the Barrier Block ‘trips’, meaning that the two separate lines are disconnected.

In summary, Terminal Blocks - Barrier Blocks provide a person with a safe and reliable way to separate two lines of conductors that are not meant to be connected. They can also provide good insulation to prevent electro-magnetic interference. These blocks are used in a variety of different industries and applications, in which safety is of paramount importance. Ultimately, Barrier Blocks provide a safer and more robust way of isolating two separate lines of conductors.
