Designed for connection to PLC-5, SLC 500, and FlexLogix platforms, it supports communication speeds of 57.6K, 115.2K, and 230.4K baud for reliable real-time data exchange. The adapter provides a maximum capacity of eight FLEX I/O modules, enabling scalable expansion in compact DIN rail–mounted control assemblies. Featuring rotary switches for convenient node addressing, removable terminal blocks, and LED indicators for diagnostics, the 1794-ASB simplifies installation and troubleshooting in industrial environments. Key Features: Remote I/O Network Integration: Connects FLEX I/O modules directly to Allen-Bradley RIO-based controllers. Supports Up to 8 Modules: Enables scalable distributed I/O configurations within a compact system footprint. High-Speed Communication: Operates at 57.6K, 115.2K, and 230.4K baud rates for time-critical applications. Convenient Addressing: Rotary node switches allow fast configuration during installation. Diagnostic LED Indicators: Provides clear feedback for power, network status, and module faults. DIN Rail Mounting: Ensures easy installation within control cabinets and modular enclosures. Industry-Standard RIO Cable Support: Compatible with Belden 9463 for robust long-distance communication. Rugged Environmental Ratings: Designed to withstand vibration, shock, and industrial temperature ranges. Compact FLEX I/O Architecture: Enables flexible configuration for process, machine, and distributed control systems. Backward Compatibility: Integrates with legacy RIO controllers still in operation. The 1794-ASB delivers the reliability and precision required for robust RIO-based distributed I/O architectures in industrial automation environments.
