About ControlLogix-XT Systems
The ControlLogix-XT products include control and communication
system components that, when used with FLEX I/O-XT products,
provide a complete control system solution that can be used in
environments where temperatures range from -20...70 °C
(-4...158 °F).
When used independently, the ControlLogix-XT system can withstand
environments where the temperature ranges from -25...70 °C
(-13...158 °F).
ControlLogix-XT with Traditional ControlLogix Components
For more information about standard ControlLogix component
specifications and installation requirements, see the resources listed
in the Additional Resources table on
page 24 .
IMPORTANT
ControlLogix-XT system components are rated for extreme
environmental conditions only when used properly with other
Logix-XT system components. The use of ControlLogix-XT components
with traditional ControlLogix system components nullifies
extreme-environment ratings.
If a ControlLogix-XT module is used with traditional ControlLogix products,
that is, ControlLogix products not designed for extreme environments, the
ControlLogix-XT module can withstand only the environments specified for
the traditional ControlLogix version of the module. For example, if a
1756-EN2TXT module is used in a standard 1756-A10 chassis, the
1756-EN2TXT module can withstand only the environment specified for the
traditional 1756-EN2T module.
The ControlLogix-XT system components are designed to meet the same
and greater operational and environmental requirements as traditional
ControlLogix products.
When a ControlLogix-XT component is used as a replacement for a
traditional ControlLogix component, the functional and environmental
specifications of the traditional ControlLogix component apply.
