Product Overview
The Allen-Bradley 1761-NET-AIC is an Advanced Interface Converter (AIC+) used in MicroLogix and SLC communication systems. It is designed to provide electrical signal conversion and network isolation between RS-232 and DH-485 networks, enabling reliable multi-device serial communication in industrial automation systems.
It is commonly used when multiple controllers or HMIs need to communicate over a DH-485 network where direct RS-232 point-to-point communication is not sufficient.

Function and Working Principle
The 1761-NET-AIC acts as a communication bridge between serial devices and DH-485 networks. Since RS-232 is point-to-point, the AIC allows multiple devices to share a common communication network by converting signals into a multidrop-compatible format.
It performs:
- RS-232 to DH-485 signal conversion
- Electrical isolation between devices
- Network expansion for MicroLogix and SLC controllers
- Multi-drop communication support
This makes it essential for older Allen-Bradley serial-based automation networks.
Industrial Role
The 1761-NET-AIC is typically used in:
- MicroLogix 1000/1200/1500 systems
- SLC 500 PLC networks
- HMI-to-PLC communication setups
- Legacy DH-485 industrial networks
- Multi-device serial communication systems
It enables multiple controllers and operator interfaces to communicate on the same network.
Installation and Integration
- Mounted on DIN rail or panel
- Powered by 24V DC supply
- Connected via RS-232 and DH-485 ports
- Requires proper node addressing for network communication
- Used alongside MicroLogix PLCs and HMIs
Compatible Systems
- Allen-Bradley MicroLogix PLCs
- SLC 500 controllers
- PanelView operator terminals
- Industrial PCs with RS-232 ports
- DH-485 network devices
