The Pilz PNOZ EF Multi Link (772120) is a powerful expansion module developed for use with the PNOZmulti 2 small controller platform. Specifically designed to extend the functionality and scalability of PNOZmulti systems, the EF Multi Link provides a flexible way to network multiple base units, creating a distributed yet unified safety architecture that meets the needs of complex machinery and multi-part installations.

At its core, the PNOZ EF Multi Link facilitates communication between different PNOZmulti 2 base units, allowing safety functions to be shared and coordinated across multiple machines or system segments. This capability is particularly valuable in large-scale production environments where modular machine design is common. By linking units, engineers can implement safety strategies that span across entire lines, ensuring consistent protection and streamlined control.

The module operates on a 24 V DC supply and is highly energy-efficient, consuming just 1 W during operation. This low power demand makes it suitable for installations with strict energy efficiency requirements, as well as large systems where numerous expansion modules are deployed. As with other modules in the PNOZmulti 2 series, the EF Multi Link sources its power directly from the system, ensuring simple integration and minimal wiring effort.

A key advantage of this expansion module is its compact, modular design. Intended for DIN rail mounting, it fits neatly alongside base units and other expansion modules, conserving valuable control cabinet space. Its streamlined installation process reduces setup time and simplifies wiring, allowing engineers to expand safety systems quickly and efficiently.

The EF Multi Link’s functionality extends beyond hardware connectivity—it also supports flexible configuration through the PNOZmulti Configurator software. Engineers can easily define how safety signals are exchanged between linked units, tailoring the system’s performance to the specific requirements of the application. This enables both scalability and adaptability, ensuring the safety system can evolve in line with production changes.

Applications for the PNOZ EF Multi Link are wide-ranging and include automotive manufacturing, packaging systems, process automation, and any environment where machines operate as part of interconnected systems. Its ability to network multiple base units makes it a cost-effective solution for maintaining safety integrity without overcomplicating system architecture.

In summary, the Pilz PNOZ EF Multi Link (772120) provides a simple, scalable, and efficient way to connect multiple PNOZmulti 2 controllers into a unified safety system. With its low power consumption, compact modular design, and support for distributed safety applications, it plays a crucial role in enabling flexible, future-proof safety architectures across modern industrial environments.
