Product Overview
The 1794-OB8 is an Allen-Bradley Flex I/O digital DC output module designed for sourcing current applications within the Flex, Flex Ex, and Flex XT I/O system platforms. It provides eight sourcing outputs at 24 V DC nominal and is typically used to interface control systems with discrete field devices such as indicators, relays, or solenoids. The module mounts on Flex I/O terminal base units and is suitable for manufacturing, material handling, and general machine control systems requiring compact and removable output modules. 1794-OB8.
