B&B Electronics 485ABOIC Optically Isolated RS-485 to RS-485 PLC Converter

The B&B Electronics 485ABOIC is an optically isolated RS-485 to RS-485 PLC converter designed to sit between two RS-485 devices or networks, providing galvanic isolation to protect equipment and reduce ground-loop noise while preserving differential signaling. This model handles RS-485-to-RS-485 connections and is powered from 24 V, aligning with common industrial control panels and PLC installations where 24 VDC is the standard supply, enabling straightforward integration with existing power rails. With two RS-485 interfaces, it allows you to connect an input RS-485 side to an output RS-485 side, extending network reach and isolating each side from potentially disruptive transients and common-mode voltage differences. Ideal applications include PLC-based automation, sensor and actuator networks, and any industrial environment requiring dependable isolation between RS-485 subsystems, ensuring signal integrity across noisy factory floors.
