SICK UE45-3S13D330 Safety Relay

SICK UE45-3S13D330 Safety Relay is a 24 V DC–coil safety relay module that provides three normally-open safety contacts (3PST / 3 Form A) with a per-contact rating up to 6 A, enabling multi-channel safe switching of guards, interlocks, E-stop circuits, and other safety devices in hazardous zones. It accepts two safety input signals (IN: 2) and offers three safety switching outputs (OUT: 3), supporting compact, fail-safe control paths for guarding architectures and safety controllers or PLCs. As part of the UE45 family, the device is designed to integrate with compatible safety devices and systems to deliver reliable isolation and fault detection across multiple channels. The UE45-3S13D330 is commonly used where multiple independent safety signals must be monitored and switched in parallel or series configurations, such as door interlocks, safety gates, and protective guards on industrial machinery.
