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
ATTENTION: Prevent Electrostatic Discharge
This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation.
Follow these guidelines when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.
ATTENTION: Personnel responsible for the application of safety-related programmable electronic systems (PES) shall
be aware of the safety requirements in the application of the system and shall be trained in using the system.
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 are 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.
