The 140CPU11302 is a legacy CPU module for the Schneider Electric Modicon Quantum platform. Based on an Intel 80486 microprocessor, it provides reliable deterministic control for mid-range industrial applications, particularly for Concept and ProWORX 32 environments. It manages discrete and analog I/O, communicates via the Quantum backplane, and supports Modbus and Modbus Plus networking.

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
