Allen-Bradley 8504C-AT PC Circuit Board Control Card

The 8504C-AT PC Circuit Board Control Card is a multi-layer Printed Circuit Board Assembly (PCBA) designed for industrial machine control, signal processing, and equipment interfacing. Identified by part number 8504C-AT (alternate 8504CAT), this legacy control card is commonly installed as a direct OEM replacement in manufacturing machinery, process control systems, and other OEM equipment where reliable electronic control is required. It mounts in a chassis or control cabinet and uses machine-specific connectors and terminals to interface with sensors, relays, motors, and operator controls; the board is a standalone PCB with integrated components and weighs approximately 1 lb. Manufactured in China for indoor industrial environments, the 8504C-AT is commonly sourced as a replacement part with direct OEM 8504C-AT or refurbished 8504CAT control boards, or equivalent industrial control PCB assemblies.
