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

env

ironments 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

35.

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-CN2RXT module is used in a traditional 1756-A10 chassis, the

1756-CN2RXT module can withstand only the environment specified for the

traditional 1756-CN2R/B 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

requirements of the traditional ControlLogix component apply.
