The PSSuniversal – the NEW Modular Safety and Standard Remote I/O is the first distributed I/O platform that works with all major bus systems, as well as SafetyBUS p, the world's first safe fieldbus technology. With modular I/O slices you can stack together just a few, or as many as you need. Yellow modules are used to monitor safety-related functions; grey modules are used for standard control functions.

Pilz offers block switching where de-centralized I/O nodes can be controlled by both standard and safety PLCs, reducing the need for 2 separate I/O networks. Cabling and assembly time is dramatically cut. The PSSuniversal is lean & safe, providing tremendous cost savings and setting a new standard in I/O design.

PSSuniversal - The future-proof platform for safety AND standard

Modular structure

Modular, decentralized digital input/output modules provide a future-proof platform for safety and standard. PSSuniversal gives users an individual, economical and decentralised automation solution. Innovative, open, flexible and practical.

The modular system consists of:

• One head module
• At least one supply voltage module
• Up to a max. of 64 input/output modules for safety-related and standard applications, which can be installed in any order
• An end bracket at the start of the system to secure the system on the mounting rail
• A terminating plate with integratable end bracket at the end of the system to secure the system on the mounting rail.

System design

The head module connects the PSSuniversal to master controllers via various standard fieldbus systems. It also connects the modular system to the safe, open bus system SafetyBUS p. The head module establishes communication with all connected modules – for safety-related and standard modules.

Base modules are the carrier units for the supply voltage and input/output modules. They are used to connect the field wiring. With screw connection or cage clamp terminals.

Electronic modules are inserted on to the base modules. The benefit: they can be inserted and removed independently from the base module. They determine the function of the supply voltage or input/output module and communicate with the head module via the respective module bus.
