Product Description P/N: 1794-ACN15
Description
The Allen-Bradley 1794-ACN15 is a FLEX I/O ControlNet communication adapter designed to interface FLEX I/O modules with ControlNet networks at speeds up to 5 Mbps. The 1794-ACN15 converts incoming 24 VDC power to FlexBus backplane power while providing reliable, deterministic network communication. Its single ControlNet port, onboard diagnostics, and support for up to eight FLEX I/O modules make it a versatile option for distributed control system architectures.

Information About 1794-ACN15
The 1794-ACN15 is part of the FLEX I/O family and serves as the ControlNet communication bridge for FLEX I/O node configurations. It connects FLEX I/O modules to a ControlNet coaxial network using RG-6/U cabling and provides FlexBus output current to power adjacent modules. The adapter supports redundant media operation through Comm A and Comm B diagnostic indicators and includes dedicated LED feedback for I/O status. Designed for rugged industrial environments, the 1794-ACN15 offers wide operating temperatures, strong vibration and shock ratings, and hazardous-lo
Key Features
- ControlNet Communication Adapter: Enables high-speed 5 Mbps communication for FLEX I/O systems.
- Supports Up to Eight I/O Modules: Provides backplane power and network connectivity for modular FLEX I/O assemblies.
- Single ControlNet Port: Uses RG-6/U coax for deterministic, real-time data exchange.
- Integrated LED Diagnostics: Comm A/B and I/O status indicators monitor network health and module operation.
- Wide Power Input Range: Operates from 19.2–31.2 VDC with built-in conversion to 5 VDC FlexBus power.
- Industrial Environmental Ratings: Withstands shock, vibration, and temperatures up to 55 °C.
- DIN Rail or Panel Mounting: Supports standard industrial installation practices.
- Hazardous Location Approved: Meets North American and European Zone 2 requirements.
The 1794-ACN15 delivers the reliability and precision required for efficient ControlNet communication within FLEX I/O distributed automation systems.
