Terminal Blocks - Barrier Blocks

The 1519-ST is a versatile field wiring terminal block that facilitates secure connections between the control cabinet and the field. It is an effective way to easily connect multiple wires in one block, reducing installation time. This terminal block is often used in electrical, control, and instrumentation applications.

The 1519-ST terminal block consists of a base and a removable terminal module. It is designed with a top- and bottom-entry for external wires and allows these wires to wrap around the base and be quickly and easily connected to the terminal. The unit comes with clearance holes and studs for a variety of circuit components and offers desirable features such as higher current carrying capability, available ground connections, and the ability to quickly reconnect or modify signals.

The 1519-ST is a barrier terminal block, which is a type of terminal block designed to keep wiring components separate. Typically, barrier blocks are made of a plastic housing with two metal plates on either side. The metal plates are spaced apart and connected by a conductive barrier layer, thus providing an electrical barrier between the plates. This ensures that electrons cannot move from one plate to the other, therefore isolating the individual wiring circuits.

The working principle of a barrier block is simple. When a wire is connected to each plate, the connection is made without allowing any electricity to flow from one plate to the other. This provides an electrical isolation between the two wires, which helps to reduce interference or cross-talk between them. In addition, the barrier block prevents short circuits between either plate.

The 1519-ST terminal block offers several advantages in comparison to conventional terminal blocks. It is designed for quick and easy wiring of multiple wires with secure connections. Additionally, the internal partitioning of the terminal block provides reliable electrical isolation between each of the terminals, ensuring that the external connection is safe. Finally, the 1519-ST terminal block is also equipped with a variety of features such as built-in ground contacts, strain relief, and cable entry provisions.

The 1519-ST terminal block is an excellent choice for quick, secure, and reliable field wiring. It is easy to install and highly adaptable to different wiring requirements, making it an ideal solution for various control and instrumentation applications.
