SICK UE4400 series IP 67 remote I/O bus nodes integrate safety sensors and actuators into a flexible control system using DeviceNet Safety. Units are designed with 6 dual channel safety inputs and 2 dual channel bipolar safety outputs. SICK machine safeguarding devices such as C4000 Safety Light Curtains and S3000 Safety Laser Scanners can be intelligently integrated into the DeviceNet Safety™ field bus network using SICK Safety Data Link (SDL) technology on the UE4450 product types. This provides customers with advanced diagnostic capability and reduces the number of DeviceNet Safety node addresses required. Configuration can be done locally or remotely though DeviceNet.
