Terminal Blocks - Panel Mount provide a secure connection point between control panels and device access points. They are an ideal option for applications requiring reliable transmission of a controlled voltage, or the transmission of signals over long distances. Common applications for this type of panel mount are in the industrial automation, process control, and instrumentation sectors. This article will discuss the various application fields and the working principle of Terminal Blocks - Panel Mount.

Industries using Terminal Blocks - Panel Mount

Terminal Blocks - Panel Mount are primarily used in industrial automation, process control, and instrumentation sector. In the industrial automation sector, it is used to securely connect and control various motors and actuators as well as for transmitting signals between multiple control panels in a factory environment. Process control applications involve using panel mount terminal blocks to send various signals across a factory or chemical plant and enable the automated control systems to work in tandem. In instrumentation applications, terminal blocks are used to transmit analog and digital signals between multiple devices used for measuring and monitoring.[1]

Mechanical Construction of Terminal Blocks - Panel Mount

Terminal Blocks - Panel Mount consist of a terminal block, a base or mounting plate, and an electrical connector. The terminal block is made of a dielectric material and usually contains two parts - a contactor that accepts the incoming wire, and a connection point that receives the connector pin. This connection point is usually made of brass or stainless steel and is generally used to accept a screw-type connector.[2]

The mounting plate is where the terminal block is connected to the panel. Most of the time, the mounting plate is composed of aluminium or metal and can be attached to the panel either with screws or rivets. The electrical connector is the piece of equipment that connects the wires to the terminal block.

Methods of Connections for Terminal Blocks - Panel Mount

There are a variety of connection methods available for terminal blocks, including:

• Screw Connections: The screws on the terminal blocks are tightened with a screwdriver. It is the most common connection method for panel mount terminal blocks, as it provides a secure, electrical connection.
• Spring Connections: This type of connection uses metal clips that are either hinged or mounted on springs. Spring connections are suitable for panel mount terminal blocks and are good for situations where it is difficult to access the screw.
• Push-In Connections: Push-in connections use a small metal clip that needs to be pushed into the terminal block. This is suitable for panel mount terminal blocks as it provides a quick and easy connection.

Safety Considerations for Terminal Block - Panel Mount Usage

Before connecting any electrical wires to a terminal block, it is important to be aware of all safety concerns. Firstly, it is important to make sure that the correct voltage is being used for the application, as incorrect voltage can cause serious injury or damage the equipment. Secondly, be aware of the wire insulation, as any exposed wires may present an electrical hazard.

It is also important to note that all electrical connections should be properly secured with mechanical fasteners. This is to ensure that the wires do not come loose due to vibration or movement of the electrical components. Finally, be sure to use heat shrinkable tubes to protect exposed wires and connections from oxidation and corrosion.

Conclusion

Terminal Blocks - Panel Mount are widely used in industrial automation, process control, and instrumentation settings. They provide a secure connection point between control panels and device access points. There are various connection methods available for terminal blocks, as well as safety considerations that must be taken into account. With the right information and a quality product, terminal blocks can provide safe and reliable signal transmission for years to come.
