The Pilz PSSU H FS SN SD-R (part number 315085) is a specialised power supply module developed for the PSSu modular I/O system, ensuring reliable energy distribution to both system modules and connected peripherals. With its robust 24 V DC supply, efficient power management, and dual supply design, it provides the foundation for safe and continuous operation in industrial automation environments.

A central advantage of this module is its ability to support two distinct supply purposes. The first, U1, delivers power to the module itself and the PSSu backplane, ensuring the stable operation of the system’s logic and I/O functions. The second, U2, is dedicated to the periphery supply, powering connected field devices such as sensors, actuators, or other external components. This separation enhances system safety and availability, as faults in peripheral circuits do not compromise the functionality of the core module.

Operating on a 24 V DC supply voltage, the PSSU H FS SN SD-R integrates easily into modern automation infrastructures, where 24 V DC has become the standard for control systems. Its design guarantees stable voltage delivery even under demanding conditions, reducing the risk of unexpected shutdowns or performance issues. With a DC power consumption of 16 W, it balances energy efficiency with robust performance, supporting long-term, cost-effective operation.

The module has been designed for seamless integration into the PSSu I/O platform, Pilz’s modular automation and safety system. This modular approach allows engineers to combine base modules, communication interfaces, digital and analogue I/O, and power supply modules into a customised solution tailored to specific applications. The PSSU H FS SN SD-R plays a critical role in this setup, ensuring that both the system core and its connected devices receive consistent, reliable power.

Durability and compliance with industrial standards are built into the design. The module is capable of handling continuous operation in challenging environments, making it well-suited for industries such as automotive manufacturing, robotics, packaging, logistics, and process automation. By supporting stable and redundant power delivery, it helps maintain high system uptime and supports compliance with functional safety requirements.

Practical applications for the PSSU H FS SN SD-R include safeguarding distributed I/O systems, supporting machine control platforms, and powering safety-critical field devices. Its dual supply capability makes it especially useful in applications where system integrity must be maintained even when peripheral circuits experience interruptions.

In summary, the Pilz PSSU H FS SN SD-R (315085) is a reliable and efficient power supply module for the PSSu I/O system. With its 24 V DC operation, 16 W power consumption, dual supply design, and seamless system integration, it ensures stable and safe operation of both core modules and connected devices, making it an essential component for modern automation and safety solutions.
