SICK UE4400 IP 20 remote I/O bus nodes integrate safety sensors and actuators using DeviceNet Safety. UE4400 series IP 20 remote I/O bus nodes are configured using an EDS file via the DeviceNet Safety network. Versions include semiconductor safety inputs only, a combination of semiconductor safety inputs and safety outputs and semiconductor inputs with relay-based safety outputs.

• Solving applications up to SIL3 (IEC 61508)
• Easy upgrade of sensors and actuators on DeviceNet Safety
• Multiple safety sensors and actuators are supported
• Decentralized evaluation of safety sensors and actuators
• Easy installation using clamp-style, pluggable connectors
• IP 20 enclosure for DIN rail, panel mounting
• Only one safety field bus address for up to 16 sensors and actuators
