The Pilz PSSU BP-C 1/8 S (312610) is a backplane module designed for the PSSu I/O system, serving as the foundation for modular expansion in both automation and safety-related applications. By providing a stable base for connecting up to eight I/O modules, it enables engineers to create tailored control architectures that are flexible, compact, and scalable.

This unit stands out for its robust housing construction. The lower section of the housing is manufactured from polyamide (PA), a material known for its strength and resistance to mechanical wear, while the upper section is made from polycarbonate (PC), offering excellent impact resistance and long-term durability. Together, these materials ensure that the backplane can withstand the rigours of industrial environments, maintaining reliability even under frequent use and demanding conditions.

Environmental adaptability is another key feature. With a humidity rating of 93% relative humidity at 40 °C, the PSSU BP-C 1/8 S is designed to function reliably in facilities where moisture and variable conditions are present. This makes it particularly suitable for industries such as food processing, packaging, and general manufacturing, where environmental fluctuations are common but consistent system performance remains essential.

The module uses screw terminal connections, providing secure and vibration-resistant wiring. Screw terminals are a proven choice for industrial applications, ensuring that connections remain tight and stable even under continuous operation or in environments subject to vibration. This contributes to both system safety and long-term reliability by reducing the risk of loose connections or signal failures.

With a height of 129 mm, the backplane offers a compact form factor that fits neatly into control cabinets. Its slim design makes it possible to achieve dense and efficient layouts, maximising the use of available space while still allowing for easy access during installation and maintenance. This compactness also supports the modular nature of the PSSu system, enabling engineers to combine multiple backplanes and modules as needed.

As part of the Pilz PSSu I/O platform, the PSSU BP-C 1/8 S integrates seamlessly with input, output, and communication modules to form a complete automation and safety system. This modularity ensures long-term flexibility, allowing expansions or reconfigurations without the need for major redesigns. For system designers, this translates into reduced engineering effort, cost efficiency, and future-proof investment.

In practical use, the backplane is ideal for machine building, process control, packaging systems, and distributed automation setups, where compact, flexible, and reliable modular systems are required.

In summary, the Pilz PSSU BP-C 1/8 S delivers compact modular connectivity, durable housing, reliable screw terminal wiring, and high environmental resistance. As a core component of the Pilz PSSu system, it enables the creation of safe, efficient, and adaptable automation solutions for a wide range of industries.
