Schneider Electric 140CPU43412AC Modicon Quantum Processor

Schneider Electric's Modicon Quantum 140CPU43412AC is a Concept processor module for the Quantum automation platform, built around an 80486-based CPU. It provides one Modbus Plus port and two Modbus RS-232 serial ports for device communications within a Quantum backplane network. The AC suffix denotes a conformal-coated variant designed for harsher industrial environments, aligning with Schneider's Quantum concept processors. This CPU module fits the Quantum architecture and is used to execute control logic and manage Modbus communications for Quantum installations that require Modbus Plus alongside RS-232 links.
