The Pilz PSSU BS 2/8 C (312657) is a high-quality base module from the PSSu modular I/O system, engineered to provide a reliable foundation for flexible and scalable automation solutions. Designed with durability, environmental resilience, and ease of use in mind, this unit serves as a key component in decentralised and centralised I/O architectures.

Built to withstand relative humidity of up to 93% at 40 °C, the PSSU BS 2/8 C ensures consistent operation even in harsh or moisture-prone environments. This makes it particularly well-suited for industries where environmental conditions can fluctuate, such as food and beverage production, logistics, or outdoor automation systems.

The housing construction combines PA (polyamide) for the lower section and PC (polycarbonate) for the upper section, ensuring robust protection for internal components. This combination delivers impact resistance, durability, and lightweight handling, all while maintaining long-term reliability in industrial environments.

For wiring efficiency and secure installation, the module uses cage clamp terminals. These terminals provide fast, tool-free connections, reducing commissioning times and ensuring a reliable electrical connection that is resistant to loosening under vibration or mechanical stress. This feature is particularly advantageous in applications where machinery is subject to continuous operation and high mechanical loads.

With its compact height of 129 mm, the PSSU BS 2/8 C offers a space-saving design that integrates easily into crowded control cabinets. Despite its modest footprint, it provides the structural foundation for connecting various input/output modules in the PSSu system, enabling engineers to build tailored automation solutions that meet specific application requirements.

As part of the Pilz PSSu I/O platform, this base module integrates seamlessly with digital, analogue, and safety-related modules. Its modularity allows system designers to expand functionality as needed, supporting both small-scale applications and large, complex installations. This scalability reduces system costs over time by allowing incremental upgrades instead of full replacements.

Typical applications include machine automation, robotics, process control, and safety system integration, where robust and reliable I/O bases are required. Its rugged design and environmental resilience make it equally suitable for standard factory settings and challenging environments, ensuring operational safety and efficiency.

In summary, the Pilz PSSU BS 2/8 C (312657) is a durable, compact, and efficient base module that enhances the flexibility and reliability of the PSSu modular I/O system. With its robust housing, cage clamp terminals, and environmental resistance, it provides engineers with a trusted foundation for building safe and scalable automation architectures.
