140DAO84220
Schneider Electric
Overview
The 140DAO84220 is an output module in the Modicon Quantum range from Schneider Electric. Discrete Output Module Modicon Quantum 16-point AC Triac (Low Voltage).
Application & Technical Notes
As a modicon quantum device, the 140DAO84220 is intended for deployment in panel-based control cabinets and machine enclosures where Modicon Quantum equipment is installed. It drives actuators, relays, valves and indicators from controller commands, acting as the actuation layer between logic and the machine.
Key published characteristics include ac output, triac (bidirectional thyristor) signal handling, a 5 V DC (backplane) 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 140DAO84220, 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.
