0387090352 Application Field and Working Principle

A barrier block is a terminal block designed to provide more safety and flexibility in conveyor control and other similar applications. It combines a number of terminals in a single housing and has an internal insulation barrier to prevent contact with the high-voltage or current parts of the circuit. This ensures a high level of safety for personnel and equipment.

Applications

Barrier blocks are widely used in a variety of applications such as conveyor control, electromechanical relays, injection molding machines, industrial robotics, motor drives, robotics, and electrical control systems. They are ideal for controlling power sources such as furnace track switches, AC motors, DC drives, PLCs, HVAC systems, and other electrical or electromechanical equipment. They are also suitable for use in hazardous areas.

Advantages

• High safety – Barrier blocks have an internal insulation barrier to prevent contact with the high-voltage or current parts of the circuit, providing a high level of safety for personnel and equipment.
• Secure connection – The terminals of a barrier block allow secure connections without the risk of arcing or sparks.
• Compact size – Barrier blocks are low-profile, space-saving and easy to install.
• Versatility – Barrier blocks are available in various sizes and combinations, offering multiple connection possibilities with different wiring schemes.
• Ease of maintenance – Barrier blocks are easily serviced thanks to their simple construction and quick-disconnect terminals.
• Standardization – Barrier blocks meet the requirements of the EN 61984 (formerly VDE 0620) and IEC/PAS 61984 standards and are suitable for use in industrial, commercial, mobile, or domestic applications.

Working Principle

A barrier block consists of a number of terminals arranged in a line. The terminals, made of metal, are insulated from each other with a thin layer of insulation. The terminals are connected via a metal barrier, which provides additional protection against arcing and sparks. The barrier also helps to contain any sparks that may occur when connecting or disconnecting the terminals.

The terminals are connected to a main power source, which is typically a junction box. The output of the power source is then connected to the terminals on the barrier block. The terminals can be connected to another piece of equipment, such as a switch, relay, or motor, or to a number of different devices.

When connecting a device to the barrier block, the terminals must be firmly secured with a screwdriver to ensure a good connection and prevent arcing and sparks. The terminals can then be connected to the device’s power source via cables.

Barrier blocks are designed to be easy to service and maintain. The terminals are connected to the main power source via a quick-disconnect system, allowing the block to be easily disconnected from the power source. This makes the block easy to replace if it is damaged or if the terminals need to be rewired.

Barrier blocks are widely used in a variety of applications and can provide a secure and safe connection for controlling power sources and other equipment.
