Product Overview

The 1794-OA16 is a 16-point AC digital output module in the Allen-Bradley Flex I/O family. It provides non-isolated AC switching outputs for control system field devices. The module mounts to Flex I/O terminal bases and communicates via FlexBus. It is applied in distributed control systems for energizing relay coils, contactors, solenoids, pilot lamps, horn/siren circuits, and similar 120 VAC loads. The 1794-OA16 integrates into Flex I/O racks to support modular system expansion.
