Product Details

The Schneider 140CPU65160C conformal coated Unity processor module is a high-reliability dual-slot core control unit of Modicon Quantum PLC automation platform, designed for large-scale industrial process control systems operating under humid, dusty and corrosive working environments. This modicon quantum cpu module adopts a 32-bit RISC processor running at 266MHz clock frequency, with 1024kB built-in RAM, and supports memory expansion via PCMCIA card, up to 7168kB program memory and 8MB file storage. The PCB circuit board is coated with Humiseal 1A33 conformal coating, which can effectively protect internal electronic components against moisture, dust and corrosive gas, ensuring stable continuous operation in chemical plants, offshore platforms and other severe industrial sites. It fully supports IEC61131-3 standard programming languages and is programmed with Unity Pro / EcoStruxure Control Expert software. It can reach 10.28K boolean instructions per millisecond, delivering excellent processing performance for heavy automation tasks. This CPU integrates one 10/100Mbps Ethernet port, one Modbus serial port and one Modbus Plus communication port, supporting data exchange with local I/O modules, S908 remote I/O stations, distributed I/O stations, HMI touch screens and other field automation equipment. 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 onboard Ethernet port supports TCP/IP communication, web diagnostic function and Ethernet remote I/O scanning. The module comes with a 2×16 LCD backlight display and key switch for memory protection, supporting high-speed interrupt input, event time stamping and high-precision counter functions. A hardware watchdog timer continuously monitors program execution status and triggers safety protection actions automatically once abnormal operation occurs. It occupies two adjacent slots on Quantum backplane rack and can 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 Dec 31,2018 and end-of-service on Dec 4,2025, 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 large Modicon Quantum automation racks running Unity control software under harsh industrial environments.
