Allen-Bradley D1391B Program Counter Circuit Board

The Allen-Bradley D1391B Program Counter Circuit Board is an industrial electronic control board that delivers program sequencing, counting functions, and control logic processing for automated machinery and control systems. Equipped with a P3AP MP7183 component set and a 4700 µF electrolytic capacitor, this printed circuit board assembly provides timing and counting operations essential to machine control. It is commonly installed in manufacturing equipment, process control systems, packaging machinery, conveyor systems, and material handling equipment where precise sequencing and control logic are required. Maintenance teams, OEM engineers, and system integrators rely on the D1391B for equipment repair, control-system maintenance, retrofit projects, and replacement of failed circuit boards. Designed for internal equipment mounting in industrial automation environments, it supports reliable program sequencing and counting functions across production machinery and specialized OEM systems. Common replacements include OEM Program Counter Control Board, Industrial Sequencing Control PCB, and Machine Counter Logic Board.
