    What`s there to know about terminal blocks for control applications?

    What`s a component that forms the backbone of most motion or automation control systems but that often times goes unacknowledged? We`re talking, of course, about the hard-working terminal block. What exactly is a terminal block and what function does it serve in motion/automation systems? The most basic definition is that it provides an electrical connection point for two or more wires. Terminal blocks were originally referred to as screw terminals because a screw was used to secure wires to a conducting plate, making an electrical connection. In control systems, terminal blocks are used to connect panel-mounted equipment to power and field wiring. A typical control cabinet showing pluggable terminal blocks mounted to DIN rails with wire connections labeled for easy identification. A typical automation system inside of an equipment rack may contain any number of components (such as controllers, PLCs, I/O modules, etc.) mounted on DIN rails and connected together via terminal blocks.

    ​How to Properly Use a Terminal Block

    How to Properly Use a Terminal Block A terminal block is one method of connecting a selection of different electrical wires. They come in a variety of shapes and sizes so you can normally find one that will be compatible with whatever project you are carrying out. However, the difference between blocks can lead to problems if an incorrect type is used or if it is not connected properly. Follow the advice below so you never have to worry about encountering these issues. Step 1 - Terminal Block Type Look at the electrical equipment you are working on to see what type of connection it requires; normally you will have either a screw-in or plug-in connection. Screw-in wires are placed inside the terminal block and screwed into position, and they are most common for equipment that does not require high voltage protection. A variation on the screw-in connection is one held in place by a spring mechanism. This connector can reduce the time spent on the job because you simply clip it into place instead of removing and re

    Terminal blocks ensure safe currents as well as safe wiring of installations

    From control panels for industrial productions to fuse boxes in private homes: Terminal blocks ensure safe currents as well as safe wiring of installations. Plastics used to manufacture terminal blocks have to meet high requirements for fire protection and mechanical and thermal properties. In electrical engineering, terminals are used to connect wires and cables. Continuous safe contact has to be ensured for the connection – mechanical fixing ensures this. Terminal blocks can be arranged in any order on a mounting rail and installed with a simple snap. This defines the mechanical properties required for this material: plastics used in this application must exhibit high elasticity and good toughness – or run the risk of breakage when snapping. Connections require sufficient stiffness and strength. When handling electrical power, sparking and fires may occur. Other requirements include high temperature resistance and heat aging resistance Plastics have electrical insulating properties, which generally recommends them for electronic applications. Terminals are produced in extremely large quantities by injection molding. Economic production requires short cycle times and low maintenance cost for injection molding tools and machinery. It is also necessary to be able to produce very low (0.4 mm) wall thicknesses with the plastic. In addition, good colorability of the material plays an important role: Different colors of the terminal blocks serve to differentiate between different functions (e.g. neutral conductor, protective conductor, etc.) and ensure safe installation.
