The Pilz PSSU E F BSW – 312230 is an advanced I/O module developed for use within the Pilz PSSu (decentralised modular I/O) system. Designed to provide reliable periphery supply and robust system protection, it plays a key role in extending the functionality and safety of distributed automation architectures.

At its core, the PSSU E F BSW is equipped with a 24 V DC periphery supply (U2), specifically dedicated to powering connected field devices. This ensures stable, uninterrupted operation of sensors, actuators, and other peripheral components, making it an essential element in maintaining system performance and uptime.

One of the module’s standout features is its ability to handle supply voltage fluctuations, operating reliably within a tolerance range of -30% to +25%. This wide range makes the module particularly valuable in industrial environments where electrical stability may be inconsistent, ensuring that connected devices remain functional even under challenging power conditions.

The PSSU E F BSW also provides 3050 V potential isolation between UINT1 and U2, offering strong electrical separation for enhanced safety. This isolation protects both the module and the connected periphery from cross-voltage interference, reducing the risk of faults, improving system reliability, and safeguarding operators and equipment.

As part of the Pilz PSSu system, the module is designed for seamless integration into modular and decentralised I/O architectures. Its flexible design allows it to be combined with a wide variety of digital and analogue I/O modules, as well as communication interfaces, creating tailored solutions for both safety-related and standard automation tasks. This scalability makes it suitable for applications ranging from small machine cells to large, networked production lines.

Installation and configuration are straightforward, with the module designed for space-efficient mounting in control cabinets or distributed field stations. Once in operation, it requires minimal maintenance, providing long-term cost-effectiveness while supporting continuous industrial processes.

Typical applications for the PSSU E F BSW include powering distributed I/O networks in packaging machinery, automotive production, process industries, and material handling systems. By combining robust periphery supply with strong electrical isolation, it ensures that automation systems remain both safe and reliable in dynamic industrial settings.

In summary, the Pilz PSSU E F BSW – 312230 provides a stable periphery supply, wide tolerance for voltage fluctuations, and strong isolation protection. Compact, durable, and fully compatible with the modular PSSu system, it delivers reliability and flexibility for distributed safety and automation architectures.
