140CRA21220C
Schneider Electric
Overview
The 140CRA21220C is a DIO Drop Interface 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 dio drop interface, the 140CRA21220C is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Quantum equipment is installed. It performs a defined automation function within the control system and is selected to match the installed Schneider Electric platform.
Key published characteristics include a 24 VDC rating. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Avoid condensation — the rated humidity is 95 % without condensation; store and operate the module in a dry, pollution-degree-appropriate enclosure. Inspect terminals and connectors for corrosion or looseness, and confirm the module seats correctly in its carrier. 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 140CRA21220C, 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 mechanical and electrical compatibility with your Modicon Quantum installation and the intended function. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
