Description

The Allen-Bradley 1769-ADN is a CompactLogix DeviceNet Adapter module designed to interface 1769 Compact I/O modules with a DeviceNet network. This adapter allows for the expansion of I/O capabilities, enabling a remote 1769 I/O rack to communicate with a DeviceNet master controller. It is a compact, high-performance solution for distributed control applications requiring reliable fieldbus connectivity.

Features

• Supports up to 30 Compact I/O modules per adapter.
• Provides 180 words of input and 180 words of output data capacity.
• Single-channel DeviceNet interface for seamless network integration.
• Compact form factor suitable for space-constrained control cabinets.
• Designed for robust performance in industrial environments.
