The Allen-Bradley 1761-NET-AIC, commonly known as the AIC+, serves as the essential bridge for networking legacy MicroLogix and other SLC-based controllers. This 100% Brand New advanced interface converter facilitates seamless protocol conversion between RS-232 and DH-485. It allows multiple devices—including controllers, HMIs, and PCs—to share a single DH-485 network. By providing isolated RS-232, RS-422, and RS-485 ports, the 1761-NET-AIC eliminates communication barriers in complex multi-drop or point-to-point industrial architectures.
The 1761-NET-AIC utilizes high-grade optical isolation to maintain signal integrity across diverse network nodes.

Protocol Flexibility: This module converts standard RS-232 signals into the DH-485 protocol. This allows modern programming terminals or PanelView HMIs to interface with MicroLogix 1000, 1200, and 1500 controllers without proprietary cable restrictions.
Superior Optical Isolation: The 500V DC internal isolation protects your controller's sensitive logic circuits from ground loops and electrical noise common in long-distance RS-48
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
