The 1761-NET-AIC (AIC+) Advanced Interface Converter from Rockwell Automation is a serial communication and protocol conversion module used in MicroLogix and SLC systems.
Its main role is to enable communication between devices that use different serial standards, especially:
- RS-232
- RS-485
- DH-485 network
It is commonly used when a MicroLogix PLC needs to communicate with multiple devices over a DH-485 multidrop network, or when isolating and converting serial signals in legacy systems.
Main Functions
The 1761-NET-AIC is used to:
- Convert RS-232 ↔ RS-485 electrical signals
- Enable DH-485 network communication
- Provide electrical isolation between devices
- Support multidrop serial networks (multiple PLCs/devices on one bus)
- Allow communication between MicroLogix, SLC 500, HMIs, and PCs
It is not a PLC module—only a communication interface device.
