Schneider Electric
Overview
The 140NOC78000C is an Ethernet DIO Network Module in the Modicon Quantum range from Schneider Electric. It extends Modicon Quantum connectivity through its onboard communication interface.
Application & Technical Notes
As an ethernet dio network module, the 140NOC78000C is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Quantum equipment is installed. It bridges the controller to higher-level networks, HMIs, SCADA and peer devices, carrying configuration, process data and diagnostics.
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
Confirm network addressing, baud/rate and topology match the rest of the system; keep firmware consistent across the cell. 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 140NOC78000C, 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.
Match the protocol, connector and topology to the rest of the Modicon Quantum network and to the peer devices already installed. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
