IMPORTANT The ControlLogix-XT controllers function in the same way as the traditional
controllers. The ControlLogix-XT products include control and communication
system components that are conformally coated for extended protection in
harsh, corrosive environments:
• When used with FLEX I/O-XT™ products, the ControlLogix-XT system can
withstand temperature ranges from -20…70 °C (-4…158 °F).
• When used independently, the ControlLogix-XT system can withstand
temperature ranges from -25…70 °C (-13…158 °F).
