Absolute Encoders on EtherNet/IP

Our EtherNet/IP™ Absolute Encoders are designed with an embedded EtherNet/IP switch and dual Ethernet ports to support linear networks and Device Level Ring topologies. By providing auxiliary feedback directly through an EtherNet/IP network, these encoders eliminate the need for point-to-point wiring. These encoders are designed for high performance and reliability in harsh industrial environments. Our encoder offerings include models that brings in the encoder as a feedback only axis for machine applications using integrated motion on EtherNet/IP. We also offer models designed for safety applications that require speed, direction, or position monitoring safety functions.

What's New

Our new 843ES CIP Safety over EtherNet/IP™ Encoders are designed for safety applications that require speed, direction, or position monitoring safety functions. These encoders support the GuardLogix controller-based safety functions, according to IEC 61800-5-2, in the Studio 5000™ Logix Designer application. By providing auxiliary feedback directly through an EtherNet/IP network on CIP Safety, it makes it easy to achieve the desired safety integrity or performance level by reducing the number of components needed and utilizing the already available advanced drive safety instructions. When used as part of an integrated safety system that includes a GuardLogix® 5580ES controller or Compact GuardLogix 5380ES controller, the 843ES CIP Safety Encoder provides safety ratings up to and including SIL CL3 and PLe Cat 3. (Studio 5000 Logix Designer® application version 31 or later is required.)

New Product Features

  • PLe capable according to ISO 13849-1 and 13849-2, and SIL 3 capable according to IEC 61800-5-2, IEC 62061, and IEC 61508
  • Safety-related communication performed via CIP Safety connections over EtherNet/IP
    • Reduces overall system wiring during installation and potential points of failure that results to less downtime and troubleshooting, saving time and money
  • Dual Ethernet ports to support linear and Device Level Ring topologies
  • Configurable resolution per revolution: 1…32,768 for the safety connection and 1…262,144 for the standard connection
  • IP67 protection class
