The PSS67 PLC is the first safe and compact PLC controller with protection type IP67 for cabinet-free automation. It can be fully integrated into the automaton system PSS 4000 and it can be used for both safety and automation functions. http://www.pilz.com
For your automation project there is a large selection of I/O modules for safety-related, non-safety-related, digital and analogue signal processing. When individual changes are made to the system at a later date, simply add new modules or exchange existing ones. That gives you extreme flexibility.
The PLC controllers PSSuniversal are a part of the automation system PSS 4000, and they are available for simple and sophisticated automation projects. With the PLC controllers we offer control systems that enable you to control both automation and safety functions within a project. Our PLC control systems are modular, i.e. you can put them together to suit your requirement. To do this, various head modules (with the main processor) and numerous I/O modules for safety and automation functions are available. You can simply adapt the system structure to suit your requirements. You can add or exchange the modules at will. http://www.pilz.com
