Preface
About GuardLogix
Controllers
Two lines of 1756 GuardLogix controllers are available. These controllers share
many features but also have some differences.
Table 1 provides a brief overview
of those differences.
Extreme Environment Controllers
The extreme environment GuardLogix controller, catalog numbers
1756-L73SXT and 1756-L7SPXT, provide the same functionality as the
1756-L73S controller, but is designed to withstand temperatures of
-25...+70 °C (13...+158 °F).
Armor GuardLogix Controllers
The Armor™ GuardLogix controllers (catalog numbers 1756-L72EROMS and
1756-L73EROMS) combine a 1756-L72S or 1756-L73S GuardLogix
controller and safety partner with two EtherNet/IP™, DLR-capable
communication channels in an IP67-rated housing for mounting on a machine.
For more information on the Armor GuardLogix controller, refer to the Armor
GuardLogix Controller Installation Instructions, publication
1756-IN060.
Though the 1756-L72EROMS and 1756-L73EROMS controllers have
functionality identical to that of the 1756-L72S and 1756-L73S controllers,

IMPORTANT Logix-XT system components are rated for extreme environmental
conditions only when used properly with other Logix-XT system
components. The use of Logix-XT components with traditional Logix system
components nullifies extreme-environment ratings.
