Square D's PLC
Modicon Momentum programmable logic controllers are available with conformal coatings, allowing controllers to withstand corrosive and high humidity environments better than the company's standard PLCs. Conformal coating acts as a barrier against moisture, fungus, dust and other environmental contaminants in the water/wastewater and oil and gas industries. Instead of NEMA 4 or 4X enclosures, controllers with a conformal coating may be installed in less expensive NEMA 1 or 2 enclosures.
