Cincinnati Milacron 3-531-3280A Timer Board

The Cincinnati Milacron 3-531-3280A Timer Board (also listed as 35313280A) is a Maximiser timer PCB used in Milacron CNC control systems to govern machine-cycle timing. As a dedicated timing module, it provides sequencing logic that coordinates tool movement, spindle control, and peripheral functions within the Maximiser platform, interfacing with other I/O boards to synchronize operations during a CNC cycle. Historically deployed in Cincinnati Milacron machines that use the 3-531-series timer architecture, this board is commonly found as a used or refurbished component sold under the 3-531-3280A or 35313280A identifiers by specialist suppliers, service shops, and aftermarket marketplaces; refurbishers typically offer diagnostic evaluation, component repair, and complete rebuilding of the unit. Before purchase, verify compatibility with your machine’s control revision and wiring harness, since this is an older Milacron module that appears in legacy configurations and may require matching firmware or harness connectors to function correctly.
