Conformal Coating
Conformal coating is now available on select ControlLogix® products to help protect your automation systems from hostile and harsh environments. Rockwell Automation tested these products for the equivalent of 10 years in an ISA G3 Group A classified environment. These products are identified by the "K" suffix in the catalog number and they
- Help to protect circuitry against exposure to pollution, moisture, temperature variation, salt spray, organic attack (fungus), and aggressive chemicals and vapors
- Offer improved product life cycle when exposed to corrosive environments by maintaining long-term surface insulation resistance (SIR) ensuring operational integrity of the assembly
