0200046 Application Field and Working Principle of Terminal Blocks - Accessories - JumpersTerminal blocks - accessories - jumpers are accessories used in the automation industry for achieving efficient electrical switching between two or more electronic devices. Combining the functions of isolation, safety, and wiring with the added benefit of avoiding complicated manual labor, terminal block accessories provide a convenient and reliable means of making electrical connections.Terminal block accessories are most commonly used in control systems that rely on power and signal transmission, such as programmable logic controllers (PLCs), electric motors, digital input and output devices (I/O), and discrete input and output devices (D/I/O). For example, terminal blocks used in PLCs may be used to connect the device to an external power source, connect digital input devices to the PLC, or connect various digital output devices to the PLC.In the past, traditional screw terminals, such as multi-pin terminals, were used for such connections. However, modern terminal blocks with snap-in contacts offer more convenience in making electrical connections. Furthermore, they provide multiple safety features such as insulation, overload protection, and anti-vibration protection.Jumpers are often used in combination with terminal blocks to connect two or more conductor blocks together. Depending on the model, these jumpers can be inserted or withdrawn in a matter of seconds.In addition to being used for connecting multiple power and signal cables, terminal blocks - accessories - jumpers can also be used for controlling or monitoring electrical equipment. Examples of this application include lowering or raising a heat control device, adjusting a speed control circuit, or monitoring a temperature.Terminal blocks - accessories - jumpers are also useful for monitoring electrical current. This is achieved by mounting small miniature circuit breakers or current sensing breakers on the terminal blocks. These devices are able to measure the current drawn from the circuit and send an alarm if the current suddenly drops or rises beyond specified limits.Terminal blocks - accessories - jumpers provide a safe, efficient, and reliable way of connecting power and signal cables when building or configuring control systems. By combining multiple safety features with snap-in contacts, these systems allow quick and easy installation or removal of conductors. Furthermore, they can be used for controlling and monitoring a variety of electrical systems.
