Terminal blocks (also known as barrier blocks) are electrical components used in industrial automation systems and instrumentation configurations. They serve to provide a convenient, standardized connection point between two pieces of equipment. Commonly, the terminal blocks in the application field are composed of two parts, an insulative part, and a contact part, connected together by screws, rivets, nuts, and bolts. The insulation part is provided for grounding purposes and to protect against electric shock.The primary function of a terminal block is to provide an electrical connection point for two or more wire conductor(s). They provide an accessible method for connecting wires to devices such as sensors, electric current sources, and a wide variety of electronic components. They also provide a mechanical and electrical connection between two devices.Terminal blocks can be divided into two categories, barrier blocks and disconnect blocks. Barrier blocks, which are most commonly used, consist of a metal framework with a series of sliding contacts inside and an external terminal for connection to another piece of equipment. Disconnect blocks have a built-in break-away feature that isolates the connection when the lever is pulled or the button is released.The most important feature of a barrier block is that it prevents short-circuiting between its two poles. The terminal block is designed to contain a pair of accompanying electrical contacts located on the edges of a frame, which are bridged together by two sets of sliding plates. When the boundary between the two contacts is satisfied, the plate between them can easily slide along the length of the frame and form an electrical connection. The contact surfaces remain isolated from each other when the plate is not sliding, thus preventing short-circuiting between the two contacts.The working principle of the 1546700-8 terminal block is simple. When the connection is made, the contacts inside the barrier block are bridged and the electrical circuit is complete. Any changes in the contact arrangement are resulting from manual adjustment to the sliding plates along the length of the frame. The operating procedure is also straightforward. The contacts are pressed together and arranged in the desired configuration. The sliding plates are then adjusted and secured to form the electrical connection between the contacts.In conclusion, the 1546700-8 terminal block is an effective component for constructing reliable electrical connections in industrial automation systems and instrumentation configurations. It is easy to use and provides a safe, robust connection between two components. It is an invaluable piece of machinery in ensuring the efficiency of electrical installations.
