Shape coating
Form coatings are currently available on some ControlLogix® products to help protect automation systems against harsh environments. Rockwell Automation tested these products in the ISA G3 Group A classification environment for the equivalent of 10 years of use. These products are identified by the "K" suffix in the product catalog number, which
Helps protect circuits from exposure to pollution, moisture, temperature changes, salt spray, organic corrosion (mold) and corrosive chemicals and vapors
Insulation resistance (SIR) is maintained for a long time to ensure the operational integrity of the unit and has a long product life cycle when used in corrosive environments
