Information About 1794-ASB
The 1794-ASB is part of the Allen-Bradley FLEX I/O 1794 series and serves as a Remote I/O adapter for integrating distributed FLEX I/O modules into RIO-based control systems. 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.
