The Original New SICK UE410-MU3T5 (6026136) is a main module for the Flexi Classic safety controller series, designed for machine safety systems requiring configurable logic and reliable protection control. It provides a central processing unit that combines safety inputs, switching inputs, and safety outputs with configurable logic functions, achieving SIL 3 (IEC 61508), SILCL 3 (EN 62061), PL e, and Category 4 (EN ISO 13849) safety performance. The module is configured via rotary switches for straightforward setup, supports modular expansion, and features plug-in screw terminals for fast module replacement. Powerful PNP semiconductor outputs (2 A each) allow the removal of external relays, while clear LED indicators simplify diagnostics and reduce downtime.
