SICK’s UE4470 Safety Network Controller devices integrate and evaluate any combination of safety input and actuator devices into DeviceNet Safety networks using local or remote safety capable inputs and outputs. Safety devices can now be logically combined for coherent machine safety control strategies. Applications include packaging machinery, robot cells, machine tools and transfer lines.

Status, diagnostic and error information can be easily accessed locally or through the network. Integrated basic and application specific function blocks are provided for simple and complex control capability. Logical operations include: AND, OR, Exclusive OR, Exclusive NOR, NOT, ON Delay timer, OFF Delay Timer, Restart Inhibit, External Device Monitoring (EDM), Emergency Stop, Safety Gate Monitoring, ESPE/AOPD (e.g. Safety Light Curtain), Enabling Switch, Two-Hand Control, Automatic/Manual Reset, and User Selector Switch.

• Solving applications up to Category 4 (EN954-1) and up to SIL3 (IEC 61508)
• Local/Remote connection of safety sensors and actuators
• Decentralized evaluation of safety sensors and actuators
• Easy upgrade of installed base sensors and actuators
• Easy implimentation of safety rated logic and control
• Large library of approved safety rated function blocks
• Remote configuration of SICK intelligent safety devices via the network
