Product Details:

Schneider 140CPU67260 is a rack-mounted Unity hot standby processor module for the Modicon Quantum PLC automation platform. Powered by a 266MHz processor with 3072kB RAM, this redundant CPU supports Unity Pro programming software and is built for critical control systems requiring uninterrupted operation. It can be configured in primary and standby pairs, synchronizing program data and system status in real time. When the main CPU encounters a fault, the standby processor will take over control seamlessly without system shutdown. The 140CPU67260 integrates multimode Ethernet, Modbus Plus and USB communication ports, supporting stable data exchange with HMI, SCADA and remote I/O stations. It can handle up to 31 remote I/O stations and 63 distributed I/O stations to build large-scale industrial control systems. Built-in comprehensive self-diagnostic functions detect rack bus, module and hardware faults, with front panel LED indicators to display running status and fault alarms for fast on-site inspection and maintenance. Industrial-grade circuit design delivers excellent resistance to vibration and electromagnetic interference, suitable for long-term continuous operation in power plants, petrochemical plants and process manufacturing facilities. Installed in standard Quantum rack slots, this CPU communicates reliably with the backplane and various I/O modules to construct a fully redundant control system. Widely used in high-availability process automation projects, this redundant processor serves as the core control unit of safety-critical automation systems. It minimizes production downtime caused by CPU failures and ensures safe and stable operation of key industrial assets.
