Product Details

The Schneider 140CPU65260 Unity processor module is a high-capacity dual-slot core control unit of Modicon Quantum PLC automation platform, designed for large and complex industrial process control systems with heavy data processing and multi-network communication requirements. This modicon quantum cpu module adopts a 32-bit RISC processor running at 266MHz clock frequency, equipped with 3072kB built-in RAM, and supports memory expansion via PCMCIA card. It fully supports IEC61131-3 standard programming languages and operates with Unity Pro / EcoStruxure Control Expert software. It 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 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 large Modicon Quantum automation racks running Unity control software.
