Allen-Bradley D073660-180603-21 Circuit Board Card

The D073660-180603-21 Circuit Board Card is a legacy electronic control PCB assembly used in industrial equipment and OEM control systems to process signals, manage system functions, and interface with connected devices. As an electronic control or interface module, it supports control, signal processing, or interface roles within host equipment, typically installed in industrial machinery, control cabinets, electronic assemblies, and legacy automation systems. The board is designed as a PCB assembly with mounting options that can be chassis or panel mounted depending on configuration, and it offers edge connector and/or terminal connections depending on revision. Cooling is passive, relying on natural convection. This component is commonly used for equipment repairs, refurbishment of legacy systems, and replacement of failed electronic assemblies, with the associated numbers D073658 and D073659 linked to its schematic and drill files. Environmentally, it is suited for industrial control systems and OEM machinery, where board-level control or communication functions are required. As a legacy part with limited publicly available documentation, it is typically swapped as an exact D073660 circuit board card, refurbished D073660 PCB assembly, or custom repaired D073660 control board when maintaining older equipment.
