842E EtherNet/IP Absolute Encoders - technologybsa.com

1 842E EtherNet/IP Absolute EncodersDual Port Ethernet with Embedded Switch and DLR Allen-Bradley Encoders are a high-quality complement to Rockwell Automation PLC-based motion control. Our Encoders provide Absolute feedback for position control and high resolution incremental feedback for speed control. They also offer preferred compatibility with other Allen-Bradley servo positioning controls to deliver a complete application Port EtherNet/IP EncoderThe latest addition to the Allen-Bradley offering is the 842E with industry-standard EtherNet/IP interface.

2 This new encoder comes standard with dual port Ethernet and M12 connectors thus providing customers with an easy, money-saving installation. It also includes an embedded EtherNet/IP switch to connect additional E/IP capable product in series and/or support a Device Level Ring (DLR) for Ethernet media redundancy. Targeted for high performance and reliability in harsh industrial environments, the 842E EtherNet/IP encoder provides high resolution Absolute positioning. Available in single-turn 18 bit resolution and multi-turn 30 bit resolution, this new high-resolution Absolute encoder is ideal for automotive, material handling, general factory automation applications.

7 The size of a machine s footprint is becoming very important today. With the introduction of the the kinetix 5500 , Rockwell Automation has greatly reduced the footprint required for the control panel. By utilizing a single network, the 842E-CM contributes to this footprint reduction by placing aux feedback requirements out of the panel and right on the Allen-Bradley 842E-CM encoder is a creative solution for these applications that complements the new kinetix 5500 architecture. By providing auxiliary feedback directly through the EtherNet/IP network, the 842E-CM eliminates the need for point-to-point wiring while allowing customers to use the encoder in a variety of network topologies.

8 What also makes this product truly unique is that it takes advantage of CIP Sync and CIP Motion Technology, a time synchronization extension for the Common Industrial Protocol (fully compliant with IEEE-1588). Using CIP Sync and CIP Motion Technology, the encoder provides a timestamp associated with all data delivered to and from the controller to allow it and the entire system to be synchronized with the master clock reference on sub-microsecond to Premier Integration between the 842E-CM and Allen-Bradley Logix controllers provides a seamless user experience.
