Cincinnati Milacron 3-531-3742A Logic Processing Module

Cincinnati Milacron 3-531-3742A LPM-2 Logic Processing Module is a printed‑circuit‑board logic card that serves as the central processing element in Milacron’s Mini‑Maxi Miser LPM‑2 control family. Identified in catalogs as the 3‑531‑3742A PC board, this logic board handles sequencing and I/O for legacy Milacron control configurations, typically used in older Cincinnati Milacron injection‑molding and CNC‑related equipment. Suppliers and repair shops classify the part as the LPM‑2 card and note that it has been discontinued by the manufacturer, with current availability often limited to refurbished or repaired units through Milacron‑spares specialists. Typical applications involve older Milacron controls where the LPM‑2 module coordinates logic decisions and timing across connected subsystems, contributing to machine cycles and control logic within the system architecture. As part of the Mini‑Maxi Miser ecosystem, the 3‑531‑3742A card is commonly paired with other LPM‑2 components to restore or sustain legacy equipment, and it is frequently sourced through distributors that offer Milacron legacy boards and repair services. This description reflects documented usage of the 3‑531‑3742A/LPM‑2 logic board within Milacron control fleets and aims to help technicians and buyers identify a genuine replacement that matches the part number and control family.
