The Pilz PSSU BS-R 1/8 C (part number 312653) is a robust base module designed for the PSSu modular I/O system, offering secure connectivity and dependable performance in safety and automation environments. Engineered with high-quality materials and a space-efficient design, this module ensures reliable operation in both standard and demanding industrial conditions.

At its core, the PSSU BS-R 1/8 C provides eight fixed terminals, making it an essential interface between field devices and the PSSu system. Its compact structure supports efficient wiring and contributes to streamlined installations in control cabinets or distributed systems. This makes it particularly valuable for engineers seeking to design modular systems that balance flexibility with space efficiency.

The module features cage clamp terminals, a proven connection technology that ensures vibration-resistant and maintenance-friendly wiring. Cage clamp terminals provide a secure hold on conductors, even under mechanical stress, while also allowing fast and straightforward wiring during commissioning or maintenance. This reduces setup time, minimises wiring errors, and ensures consistent performance throughout the life of the installation.

Durability is a central strength of this base module. Constructed from polyamide (PA) for the lower housing and polycarbonate (PC) for the upper section, the unit combines robustness with resistance to wear and environmental influences. These materials are widely recognised for their mechanical stability and insulating properties, ensuring reliable performance in harsh industrial environments.

The PSSU BS-R 1/8 C is designed to perform reliably in conditions of up to 93% relative humidity at 40 °C, making it suitable for facilities where condensation and moisture may be a concern. This resilience ensures system stability even in less-than-ideal conditions, supporting continuous operation without compromising performance.

As part of the PSSu I/O system, the BS-R 1/8 C integrates seamlessly with other Pilz modules, enabling flexible configuration to meet the exact needs of automation and safety applications. Its modularity allows engineers to tailor systems by combining digital inputs, outputs, communication modules, and base modules, all while maintaining compliance with international safety standards.

Applications for this module span machine automation, robotics, packaging, process industries, and distributed I/O installations, where reliable connections and robust performance are essential. It is particularly suitable for environments requiring high uptime, safety compliance, and secure wiring solutions.

In summary, the Pilz PSSU BS-R 1/8 C (312653) is a durable and reliable base module for the PSSu system. With its eight fixed terminals, cage clamp connection technology, robust housing materials, and ability to operate in high humidity, it offers engineers a dependable foundation for building safe, efficient, and long-lasting automation architectures.
