140CPU67261
Schneider Electric
Overview
The 140CPU67261 is a Modicon Quantum in the Modicon Quantum range from Schneider Electric. It is engineered for industrial automation duties within the Modicon Quantum ecosystem.
Application & Technical Notes
As a modicon quantum, the 140CPU67261 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.
Key published characteristics include an operating temperature range of 0°C to 60°C, rack mountable mounting. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Respect the published operating temperature window (0°C to 60°C); do not exceed it during commissioning or in enclosed panels without airflow. For storage and transit, keep the unit within Range -40°C to 85°C. 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 140CPU67261, 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.
