140DDI84100C
Schneider Electric
Overview
The 140DDI84100C is a Dc discrete input modules in the Modicon Quantum automation platform range from Schneider Electric. It is engineered for industrial automation duties within the Modicon Quantum ecosystem.
Application & Technical Notes
As a dc discrete input modules, the 140DDI84100C 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 Limits 10 to 60 V rating, an operating temperature range of 32…140 °F (0…60 °C). 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 (32…140 °F (0…60 °C)); do not exceed it during commissioning or in enclosed panels without airflow. For storage and transit, keep the unit within -40…185 °F (-40…85 °C). Avoid condensation — the rated humidity is 95 % without condensation; store and operate the module in a dry, pollution-degree-appropriate enclosure. 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 140DDI84100C, 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.

Specifications
The 140DDI84100C discrete input module, part of Schneider Electric's Modicon Quantum series, features 16 discrete inputs organized into 8 channels. It has input voltage limits ranging from 10 to 60 volts with an absolute maximum of 75 volts, ensuring versatility in various applications.
Description
| Note | The Schneider Electric 140DDI84100C is a discrete input module belonging to the Modicon Quantum series. It is designed to accommodate 16 discrete inputs split into 8 groups. The module operates within input voltage limits of 10 to 60 V, reaching an absolute maximum of 75 V, which allows for compatibility with a variety of signal levels. Addressing is done with just one input word, streamlining configuration. Designed for efficient operation, this module can handle switching frequencies up to 100 Hz, making it suitable for applications requiring prompt signal processing. Its response time is rated at 4 milliseconds, facilitating quick reaction to input changes. Enhanced safety is provided through an isolation rating of 2500 Vrms between the group and the bus, which protects the control system from voltage spikes and electrical noise. The device consumes minimal power with a dissipation rate of only 1 watt. It includes local signaling with an LED, providing visual feedback on operational status. Weighing 0.3 kg, the module is lightweight and easy to incorporate into existing setups. Furthermore, it demonstrates resistance to electrostatic discharge (4 kV / 8 kV) and can endure electromagnetic field interference of up to 10 V/m, ensuring reliable performance in challenging environments. |
