Overview
The Allen-Bradley 1761-NET-AIC Series B is an AIC+ Advanced Interface Converter engineered to facilitate seamless communication between MicroLogix 1000 controllers and networked devices. This compact conversion module functions as both a point-to-point isolator and an RS-232 to RS-485 isolator, making it essential for maintaining signal integrity in DH-485 network topologies. The 1761-NET-AIC bridges legacy automation equipment with modern control architectures, simplifying integration in retrofit and modernization projects.
