Rockwell Automation Guardmaster Allen-Bradley 440R-S35001 - Preface

Rockwell Automation Publication 440R-RM003A-EN-P - July 2021 5
Preface
A number of older Allen-Bradley Guardmaster® safety relays are discontinued
and no longer available for sale. This publication suggests examples for how to
convert these existing safety relay applications to safety relays with the latest
technologies.
The products that are described in this publication can be used in various
ways. Therefore, you must verify that each application and use of this control
equipment meets all performance and safety requirements. Designers must
consider applicable laws, regulations, codes, and standards.
The wiring diagrams in this publication are intended as examples. Because
many variables and requirements are associated with any particular
installation, Rockwell Automation does not assume responsibility or liability
for actual use that is based on these examples.
The following MSR safety relays will continue to be offered for the foreseeable
future (five or more years).
