RELIANCE 802803-RX Autobus Interface Module

RELIANCE 802803-RX Autobus Interface Module is a vintage interface device designed to link a Rockwell/RELIANCE controller with a Reliance Autobus fieldbus in Reliance Automate installations. The part number 802803-RX appears in Reliance 45C35 configurations, signaling its role in older automation networks that rely on Autobus I/O modules for sensing and control. As an Autobus interface, the module acts as the bridge between the central PLC and Autobus peripherals, enabling bidirectional data exchange across the Autobus network and supporting the integration of legacy I/O into a Rockwell Automation ecosystem. Typical applications include refurbishment, retrofit, or ongoing operation of legacy packaging, manufacturing, and process lines that continue to depend on Autobus communications. When evaluating this module for purchase, verify compatibility with your controller family, confirm the Autobus topology used in your plant, and ensure proper physical mounting and terminal wiring to match the Autobus interface requirements. This model remains relevant primarily for restoration or maintenance of older Reliance Autobus systems, where continuity of control and data flow across the Autobus bus is essential. Buyers should consult legacy Rockwell and Reliance documentation to confirm that 802803-RX is the correct Autobus interface for their specific PLC and Autobus module set, avoiding mismatches that could impede communication or require additional adapters.
