Product Overview

The 1756-PSCA2K is a conformally coated redundant power-supply chassis adapter module in the ControlLogix platform. The module interfaces dual power supplies to maintain chassis power continuity by connecting two power sources to the backplane. Typical industrial usage includes redundant power configurations in process control cabinets and harsh environments requiring conformal coating protection. 1756-PSCA2K supports power continuity in mission-critical installations.
