140DAI74000C
Schneider Electric
Overview
The 140DAI74000C is a Discrete input module 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 discrete input module, the 140DAI74000C is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Quantum equipment is installed. It converts field signals (sensors, switches, transmitters) into the digital or analogue values the controller processes, forming the acquisition layer of the automation scheme.
Key published characteristics include a 230 VAC rating. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Verify field wiring, shielding and grounding at installation; check terminal torque and confirm signal types match the configured range. Periodically inspect for loose terminations, induced noise and channel-level diagnostics reported by the controller. 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 140DAI74000C, 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 module matches your Modicon Quantum rack, the required channel count, signal type and voltage, and the firmware/configuration of the controller. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.
