POINT I/O | Allen-Bradley | 1734-ACNR /A Point I/O ControlNet Network Adapter

Product Description: Allen-Bradley 1734-ACNR

The Allen-Bradley 1734-ACNR is a ControlNet communication adapter used within the POINT I/O system. It allows POINT I/O modules to communicate over a ControlNet network, supporting both scheduled and unscheduled messaging in real-time control applications. This adapter is ideal for integrating distributed I/O into ControlNet-based systems, offering high-speed deterministic communication for mission-critical industrial automation.
