Product Overview

The 1797-CEC is a FlexEx Bus Connector (bus connector) in the Allen-Bradley 1797 FlexEx system. It functions as the interface between intrinsically-safe FlexEx modules and the standard Flex I/O backplane within a control system. Typically used in hazardous area installations to link safe I/O modules to the main bus while preserving intrinsic safety integrity, the 1797-CEC is often installed inside a suitably rated enclosure to maintain environmental and safety compliance.
