Topic
ATTENTION: Do not attempt to install this device unless the
installation instructions have been studied and understood. This
document acts as a guide for a typical installation.
Introduction
Use this publication when an application includes the Bulletin 843ES
CIP Safety™ Encoder. This publication is to help with proper
installation of the CIP Safety encoder. It provides publication
references and guidelines, product specifications, technical data, and
cabling recommendations.
It is required that installation is in accordance with these instructions
and implemented by qualified personnel.
Technical Specifications
This device is intended to be part of the safety-related control system of
a machine. Before installation, a risk assessment must be performed to
determine whether the specifications of this device are suitable for all
foreseeable operational and environmental characteristics of the
application. See
Specifications on page 1
and ratings.
Use appropriate screws, bolts, or nuts that are fitted by tools to mount
the flange of the encoder to avoid the risk of tampering. Do not over
torque the mounting hardware.

Product Overview
The Bulletin 843ES CIP Safety encoder is a SIL 3, PLe rated safety
encoder that complements the Integrated Architecture® system by
monitoring drive safety applications as a safety connection directly on
an EtherNet/IP™ network. The networked position-tracking device on
EtherNet/IP provides data to the safety controller via CIP Safety. The
Bulletin 843ES encoder was designed to help simplify safety
applications with the use of controller-based monitoring functions.
This encoder helps make it easier to achieve the desired safety integrity
level (SIL) or Performance Level (PL) because it allows the
GuardLogix® 5580 or Compact GuardLogix 5380 safety controllers to
monitor position and velocity input values directly.
