Overview

The 140CPU67261C is an Unity processor in the Modicon Quantum automation platform range from Schneider Electric. It is engineered for industrial automation duties within the Modicon Quantum ecosystem.

Application & Technical Notes

As an unity processor, the 140CPU67261C is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Quantum equipment is installed. It hosts the application program, executes the control cycle and orchestrates I/O scanning, communication and diagnostics for the station.

Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.

Maintenance & Diagnostics

Back up the application program and parameter set before any firmware or hardware change; verify the memory/real-time-clock battery where fitted and replace on schedule. Monitor the module health LED and controller diagnostics; plan spares for critical stations to minimise downtime. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.

Sourcing & Procurement

When sourcing the 140CPU67261C, distinguish three supply tiers: (1) genuine Schneider Electric stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.

Confirm the CPU matches your Modicon Quantum architecture, memory size, firmware revision and any required option/communication modules. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications

The 140CPU67261C Unity Hot Standby Processor from Schneider Electric's Modicon Quantum series is engineered for reliable operational continuity. Equipped with a 266 MHz clock frequency, it ensures efficient processing power and includes integrated support for dual local racks.

Description

NoteThe Schneider Electric 140CPU67261C operates as a robust Unity Hot Standby Processor, designed specifically for seamless integration within the Modicon Quantum series. It operates with a clock speed of 266 MHz, providing efficient processing suited for complex control environments. This processor is adaptable to various configurations with modular slot support, offering options for 2, 4, 6, 10, or even 16 slots to establish a tailored setup that meets specific system needs. Additionally, it features dual local rack integration, enhancing the local rack capacity for better performance. The modularity extends to distributed I/O capabilities, allowing up to 63 stations through a single rack and accommodating three Modbus Plus networks. Furthermore, the device supports remote I/O configurations with a capacity of 31 stations per network across S908, Quantum, and X80 protocols. The 140CPU67261C handles significant input and output volumes, supporting 31,744 remote I/O points and 8,000 distributed I/O points per network. Analog operations are covered as well, with the processor managing up to 1,984 analog remote I/O points and 500 per network. Communications are efficient via supported networks such as Ethernet TCP/IP, Modbus Plus, Profibus DP, USB, and fiber optic. The unit permits a maximum of six network connections for each communication type, including Ethernet and Modbus Plus, which enhances connectivity and flexibility. Its memory capacity includes 11,264 kB of RAM, with 1,536 kB allocated for data, and it can be expanded via an 8 MB PCMCIA card. In terms of performance, it processes approximately 10.28K Boolean or 10.07K mixed instructions every millisecond, ensuring responsive control and data handling. The unit operates with a bus current of 2,760 mA, substantial enough for various industrial applications. Notably, the hot standby configuration provides redundancy support for fault-tolerant operations, ensuring uninterrupted service during failures.
