Description

Brief Product Description

The Allen-Bradley 1761-NET-AIC is an Advanced Interface Converter (AIC+) that bridges DF1-compatible devices with DH-485 industrial networks. This module provides essential signal isolation and protocol conversion for legacy MicroLogix and SLC 500 controller families.

​Product Description

Versatile Network Bridging

The Allen-Bradley 1761-NET-AIC acts as a high-performance communication gateway, specifically engineered to connect RS-232 devices to a DH-485 multi-node network. By facilitating seamless data exchange, this adaptor allows MicroLogix 1000, 1200, and 1500 series controllers to interact with SLC 5/01, 5/02, and 5/03 processors. Because the unit provides full electrical isolation between connected equipment, it significantly reduces the risk of ground loops and signal interference in electrically noisy industrial environments. Consequently, operators can maintain stable communication across distributed PLC architectures.

Comprehensive Connectivity Options

This interface module features a flexible hardware configuration to accommodate various cabling standards. It includes a 9-pin D-shell RS-232 port, an 8-pin mini-DIN RS-232 port, and a specialized DH-485 Phoenix-style plug. Transitioning between different network speeds is straightforward, as the front-panel selector switch enables manual adjustment of the baud rate to match specific system requirements. Furthermore, the device supports point-to-point isolation and ASCII protocol bridging, making it a highly adaptable tool for integrating diverse automation hardware and operator interfaces.

Flexible Power and Installation

Engineered for industrial resilience, the 1761-NET-AIC offers dual power solutions to suit different cabinet setups. Users can provide power via a dedicated external 24V DC supply or draw current directly from the connected communication cable. A dedicated toggle switch ensures the module correctly identifies the power source, preventing operational inconsistencies. The compact housing supports both DIN rail snapping and direct panel mounting, allowing for efficient installation in space-constrained enclosures. Despite its legacy status, this adaptor remains a critical component for maintaining and expanding established Rockwell Automation networks.
