Compact safety controllers – samos® PRO
samos® PRO combines programmable safety logic, safe inputs and outputs, communication interfaces and modular expansion in a compact controller platform. Configure systems with COMPACT controllers, digital or analogue I/O modules, gateways and compatible accessories to match machine size, network architecture and required safety functions.
SOFTWARE-PROGRAMMABLE SAFETY CONTROLLER
samos® PRO is the most compact, modular and programmable safety controller for machine and plant engineering. Safety functions are parameterised in compliance with standards using the intuitive and licence-free samos ® PLAN6 software. The focus is on user-friendly, standard-compliant implementation and simple integration into higher-level systems. The control system offers integrated Ethernet protocols and interfaces for this purpose.
