Product Overview
The Allen-Bradley 1794-ACNR15 FLEX I/O™ ControlNet Adapter enables deterministic, high-speed communication for distributed I/O systems. Designed as the central node for Rockwell's FLEX platform, this adapter interfaces up to 30 FLEX I/O modules via local backplane with ControlNet™ (CNET) connectivity at 5Mbps.
- Robust metal housing (-40°C to +70°C) features IP20 protection (IP65 with kit)
- Withstands 5g vibration per IEC 60068-2-6
- Supports dual-channel media redundancy
- Achieves ≤2ms cycle times for real-time control
- Integrated network diagnostics provide LED status for node health, channel errors, and module faults
- Compatible with Studio 5000® for plug-and-play configuration
Critical Technical Specifications
