Specification

The Allen-Bradley 1794-FLA Extended Local I/O Adapter is a critical component for FlexLogix-based control systems, designed to interface seamlessly with Flex I/O modules in distributed automation networks. This adapter extends the local I/O capacity without requiring additional controllers, making it ideal for mid-range applications requiring modular expansion. Engineered for high reliability, the 1794-FLA supports up to 8 Flex I/O modules per adapter and communicates via the FlexLogix backplane at speeds up to 5 Mbps. Its compact form factor and robust enclosure allow deployment in control cabinets with limited space. The adapter features comprehensive diagnostic LEDs for rapid system health checks and is fully compatible with standard FlexLogix controllers and software tools such as RSLogix 5000. Below are the detailed technical specifications.
