The world's first CIP Safety over Ethernet/IP Safety light curtain

Allen-Bradley-450L-GuardShieldHelp protect personnel and equipment with the new Allen-Bradley 450L GuardShield presence-sensing safety light curtains. This light curtain is the first to provide CIP Safety over EtherNet/IP.


Industrial companies can help protect personnel and equipment with new presence-sensing safety light curtains from Rockwell Automation. The Allen-Bradley 450L GuardShield safety light curtains are designed to improve productivity and increase efficiency while helping provide personnel safety. This light curtain is the first product of its kind to provide CIP Safety over EtherNet/IP.


CIP Safety over EtherNet/IP enables smart safety within a Connected Enterprise and provides rich data from the plant floor. The 450L GuardShield light curtains support linear, star, and DLR networks and are ideally suited for applications where safe, easy, and frequent access to the machine is required.


Rockwell Automation 450L GuardShield POC safety light curtains are unlike traditional safety light curtains, which are based on separate transmitter and receiver units. Patented technology allows each transceiver to be used as a transmitter or receiver via an innovative plug-in module. The 450L-B is the basic model with on/off functionality. The advanced 450L-E model features integrated laser alignment, cascading, and integrated muting.

Other benefits include:

  • An active protective field that senses the entire length of a transceiver
  • Reduced system cost - reduction in the wiring of the safety circuit
  • Increased flexibility and modularity of system design and safety zoning 
  • Enables communication of diagnostics and status information to Logix Systems
