Terminal Blocks - Barrier Blocks

Barrier blocks provide power on one side and signal on the other, while permitting both high current and high-frequency signal transmissions. They are a mainstay in the engineering of control panels and the protection of signal-level circuitry. This article will explore the applications and working principles of the specific type of barrier blocks identified by the part number 0387890064.

Applications of 0387890064 Barrier Blocks

The 0387890064 barrier blocks, designed by leading industrial supply manufacturer Phoenix Contact, offer a wide array of applications for panel-level circuit design. Designed to bridge large and small current carrying pins, these versatile terminal blocks are especially suitable for combination voltage and signal blocks. This makes them ideal for use in a variety of circuits with both high-current and high-frequency pass-throughs.

For example, these blocks are often used in alarm and security circuits, as they provide a dependable way to bridge the electrical translation between two systems. In addition to alarm and security systems, the 0387890064 is also commonly used to integrate signal-level circuitry with current-level circuitry for power transfer applications. These blocks can withstand higher currents and higher frequencies than other barrier blocks, making them an ideal choice for high power circuits with both high-current and signal-level circuitry.

Working Principle of 0387890064 Barrier Blocks

The 0387890064 barrier blocks are designed to allow large DC and AC currents to pass through two different circuits. The primary DC current is sent from the power source and flows through the internal components of the block. The small AC current is sent from the signal source and passes through the insulation on the interior of the unit. This insulation helps to ensure that the signal current is not affected by the DC current.

The block is made up of two separate sections, the lower and the upper part. The lower part contains two high-current carrying pins which are lined up with each other in a narrow slot. The upper part contains two signal pins which are also lined up with each other in a narrow slot. Both portions are insulated from each other and securely fixed to the frame, ensuring that they don’t short out.

An electric surge arrestor, also known as a breaker, is also included in the product. This is used to protect the block from any sudden voltage peaks or surges. The breaker is set to trip at a certain voltage level, cutting off the power to the unit and preventing it from becoming damaged.

Conclusion

The 0387890064 barrier block is a reliable and versatile tool for bridging large and small current carrying pins, making it ideal for combination voltage and signal blocks in security and alarm systems. Its insulation helps to ensure that the signal current is not affected by the DC current, and its surge arrestor provides added protection from voltage peaks. With its wide array of applications and dependable working principles, this block helps to ensure safe, efficient signal and current transfer.
