Allen-Bradley D43842-006 Circuit Board Card

The D43842-006 circuit board card is an electronic control board used in industrial and OEM equipment to process signals, perform control functions, and provide interface capabilities within control cabinets and automation systems; part numbers include D43842-006 and D43842006. The board uses a PCB assembly form factor with chassis or panel mounting options, edge connector and/or terminal connections varying by revision, and passive cooling suitable for industrial environments that demand reliability and long service life. Frequently deployed as a replacement PCB for legacy machinery and control cabinets, it supports equipment repairs and refurbishment where board-level components are involved, with replacements that must match the original D43842-006 board revision, including refurbished D43842-006 circuit board cards or custom repaired D43842-006 PCB assemblies, where applicable. This is a legacy industrial electronic component with limited publicly available documentation, intended for use in industrial control systems, OEM machinery, and electronic equipment requiring dedicated control or interface modules.
