Product Description

The 1794-OB8 Module, part of the Allen-Bradley Flex I/O family, is an 8-Channel Digital Output module designed for industrial automation systems. It provides eight isolated output channels, supporting 12-24V DC sinking or sourcing configurations, and integrates seamlessly with Flex I/O adapters via a removable terminal block. The module operates within a temperature range of -20°C to 60°C and requires a 24V DC power supply. Compatible with networks like EtherNet/IP through adapter modules, it is widely used in manufacturing, process control, and material handling. Key advantages include high channel density, rugged design for harsh environments, and easy configuration via Rockwell Automation software. A limitation is its dependency on external adapters for network communication. The module lacks onboard diagnostics but offers reliable performance for discrete output tasks in distributed control applications.
