Allen-Bradley A26491-A Equipment Scale Control Board

Allen-Bradley A26491-A Equipment Scale Control Board is a compact, purpose-built printed circuit board designed to manage weighing-related control tasks within Rockwell Automation ecosystems. The board carries part number A26491-A and is associated with revisions D31705-1 and 1-D31771, indicating the specific variant used in compatible equipment. As an Equipment Scale Control Board, it serves as the control interface between scale sensors and the machine's control logic, enabling accurate measurement signaling and coordination with I/O and timing within a broader control system. This AB board is intended for use in industrial weighing applications where reliable, integrated scale control is required, and it aligns with Allen-Bradley hardware families to support standard mounting, cabling, and connector conventions typical of legacy AB scale interfaces. When sourcing a replacement or spare, verify that your system is engineered to accommodate the A26491-A family and consult your equipment's service documentation to confirm connector types and supported architectures. This part represents a heritage AB component, often encountered in older scale-enabled automation configurations, and is valued for its compatibility with established Rockwell Automation control workflows.
