Pilz: I/O Systems PSSuniversal – Two Solutions for Automation & Safety
June 15, 2026
PSSuniversal & PSSuniversal 2: Designed for Decentralized Networking and Transferring Safety-Related & Non-Safety-Related Signals at Field Level
Alongside the proven technology of the first generation, I/O systems PSSuniversal with head modules and corresponding I/O modules, the remote I/O system PSSuniversal 2 is continuing the success story. Improvements to mechanics, handling and diagnostics show the way to the new universal generation.
The communication modules PSSuniversal and PSSuniversal 2 are used for decentralized networking and for transferring safety-related and non-safety-related signals at field level. Using PSSuniversal, a wide range of applications can be implemented by connecting up to 64 I/O modules. You can connect the communication modules to the PLC controllers PSSuniversal or other higher-level controllers.
PSSuniversal – Proven Technology Used Worldwide
- Communication Modules for PSSuniversal: The decentralized I/O system PSSuniversal is the solution for your periphery expansion. It is connected to the higher-level controller as remote I/O.
- I/O Modules PSSuniversal: Using their I/O modules, you can adapt your controllers and I/O systems individually to your requirements.
- IP67 Modules for Cabinet-free Solutions: With PDP67 with protection type IP67, Pilz offers solutions for applications decentrally and directly in the field. You can install the modules directly on the machine. This optimizes your installation and wiring work. The module electronics are fully encapsulated. As such they are dust-tight and protected against temporary immersion. They save time, money and space in the control cabinet.
IO Link Master Meets the Challenge of Data Exchange 4.0
Thanks to the new IO Link Master module for the remote I/O System PSSuniversal 2, you can now connect IO Link devices to the system. The open, worldwide standardized IO technology supports networked production in the spirit of Industry 4.0. Your benefits: Automated parameterization and expanded diagnostics!
For communication between the remote I/O system PSSuniversal 2 and I/O Link devices such as sensors and actuators, Pilz offers the IO Link Master module PSS u2 ES 4 IOL. The open IO technology is standardized worldwide to IEC 61131-9 and enables networked production in the spirit of Industry 4.0. You can connect the IO Link Master module PSS u2 ES 4 IOL to PROFINET and to Ethernet/IP head modules.
Connection of up to four IO Link devices for standard applications is made via four Standard IO Link ports on the master module. The configuration of the IO Link devices can be stored in the IO Link Master and simply transferred when exchanging during service. This is timesaving and reduces errors as well as plant downtimes!
New Head Module with EtherNet/IP Interface for the Remote I/O System PSSuniversal 2
A head module with EtherNet/IP interface has been added to the remote I/O system PSSuniversal 2. So, the open system adapts perfectly to your existing system environment. Exchanging the head module is quick and easy: To do this, save your configuration data locally on a microSD card. Then you can easily transfer the data to the new head module with EtherNet/IP interface. The I/O modules can be used universally in an identical manner for the various safety protocols.
In the remote I/O system PSSuniversal 2, various technical and mechanical improvements have been implemented, which bring the user specific time and cost savings. Safety is a basic function of the system, as is always the case with Pilz. In addition to the EtherNET/IP head module with CIP Safety, there is a further head module available with PROFINET PROFIsafe interface.
PSSuniversal 2 – The Next Generation
- PSSuniversal 2 Communication Modules: The remote I/O system PSSuniversal 2 is the open solution for your periphery expansion. You can connect it to all common industrial communication protocols. This means it is ideally suited for incorporation into your existing control architecture.
- PSSuniversal 2 I/O Modules: Their electronic modules can be individually adapted to your existing system – simple, flexible and granular.

Industry Uses – Worldwide
Pilz I/O Systems Product Range
- PSSuniversal – Communication Modules for Decentralized I/O Systems: The PSSuniversal communication modules allow you to implement a wide variety of applications. In combination with the PSSuniversal I/O modules, you can use the modules as remote I/Os for the field level. The result is an optimum solution for customized periphery expansion. Connection to a higher-level controller is via common industrial communication protocols. The remote I/O function is also available with the special modules PSSuniversal I/O as part of the automation system PSS 4000.
- PSSuniversal – I/O Modules for Controllers and I/O Systems: The input and output modules can be combined individually to match your actual needs. A large selection of I/O modules is available for safety-related, non-safety-related, digital and analogue signal processing. When changes are made to the system at a later date, simply add new modules or exchange existing ones. This gives you an extremely high level of flexibility. PSSuniversal supports a unique mixture of safety and automation functions in one system.
- PSSuniversal 2 – Communication Modules for Remote I/O Systems: Communication modules from the remote I/O system PSSuniversal 2 are used as a head module, for connection to your existing system architecture. When combined with the I/O modules for PSSuniversal 2 you have a tailored solution for your periphery expansion. The Ethernet-based fieldbus modules are connected to the higher-level controller via standard industrial fieldbus protocols. The corresponding failsafe protocol is always supported in addition to the fieldbus protocol.
- PSSuniversal 2 – I/O Modules for Your Remote I/O System: A selection of I/O modules for safety-related and non-safety-related digital signal processing is available for the remote I/O system PSSuniversal 2. You can configure the system to fit your requirements, with a flexible mix of safety and standard functions. With PSSuniversal 2 it is very simple to adapt the system retrospectively. The configuration is performed in their software tool PASconfig.
- IP67 Modules: With the PDP67 modules, Pilz offers solutions for decentralized applications directly in the field. The modules have protection type IP67, meaning they are resistant to dirt and water. The decentralized modules optimize installation and wiring work.
