Allen-Bradley 208-40-01-102 Industrial Control Board System

The 208-40-01-102 Industrial Control Board System is a rugged, chassis- or rack-mounted electronic control board designed for machine control, signal processing, and interface functions in demanding industrial automation environments where quick field replacement matters. With Rev 3, board marking 4503A2, assembly number A-80561-3, and additional IDs TL#2, BDS2-MC2, and 8A-103, the module is intended to integrate into OEM machinery, process equipment, and manufacturing systems that require reliable control and precise signal management, though the manufacturer is unknown. It uses mixed through-hole and surface-mount components and is designed for board-level replacement, a common choice for equipment repairs, system retrofits, and the replacement of failed electronic assemblies performed by maintenance teams, OEM service technicians, and system integrators. Common replacements include a direct 208-40-01-102 replacement, OEM refurbished A-80561-3 boards, and compatible industrial control PCB assemblies, supporting legacy equipment and retrofit projects in industrial automation. Product status is Legacy / Obsolete Equipment Support, indicating it is primarily maintained through known assembly numbers and compatible replacements for ongoing maintenance of established control architectures.
