Product Details

The Schneider 140CPU31110C conformal coated Unity processor module is a high-reliability core control unit for Modicon Quantum PLC automation systems deployed in moist, dusty and corrosive industrial environments. This modicon quantum cpu module adopts a 32-bit RISC processor running at 66MHz clock frequency with integrated arithmetic coprocessor to handle floating-point calculation and complex PID control tasks efficiently. The PCB circuit board adopts conformal coating treatment, which effectively shields internal electronic components from moisture, dust and corrosive gas, ensuring stable long-term operation in chemical plants, offshore platforms and other severe industrial sites. It is equipped with 548kB built-in RAM for program and data storage, fully supports IEC61131-3 standard programming languages and can be programmed via Unity Pro or EcoStruxure Control Expert software platform. This CPU module integrates two Modbus serial ports and one Modbus Plus communication port, supporting data exchange with local I/O modules, S908 remote I/O stations, distributed I/O, HMI panels and other field automation devices. It can support up to 2 local racks, maximum 31 S908 remote I/O stations and 63 distributed I/O stations over Modbus Plus network. The module supports high-speed interrupt inputs, event time stamping and counter functions to meet precise process control requirements. A hardware watchdog timer monitors program execution status and triggers safety protection actions automatically when abnormal operation occurs. It can be directly plugged into Quantum backplane rack and cooperate with full series of Quantum power supply, I/O and communication modules to build complete distributed control systems. This original Schneider product was discontinued on December 31,2018 and end-of-service on December 31,2026, widely stocked as spare replacement parts for maintenance and upgrade of legacy industrial automation systems. It is widely deployed in power, petrochemical, metallurgy, water treatment and manufacturing plants as the core controller for medium and large Modicon Quantum automation racks operating under harsh industrial environments.
