Product Dimensions：

The 140DDI84100 is a discrete input module designed for use with the Modicon Quantum Automation Platform series of Programmable Logic Controllers (PLCs).

• Product Type: DC Discrete Input Module

• Manufacturer: Schneider Electric

• Product Line: Modicon Quantum

• Function: It is used to bring 16 digital (on/off) signals from field devices (like limit switches, pushbuttons, or proximity sensors) into the PLC system.

• Input Logic: Positive (Sink)

📋 Product Specifications (Parameters)

✨ Product Advantages

• Wide Voltage Range: Supports a wide DC voltage range ($\mathbf{10}$ to $\mathbf{60} \text{ V DC}$), offering versatility and compatibility with various field devices.

• High Reliability: As part of the Modicon Quantum line, it is designed with advanced anti-interference technology and hardware fault self-detection features, contributing to high system reliability.

• Clear Diagnostics: Equipped with $\mathbf{16}$ dedicated green LEDs for input status, plus LEDs for bus communication and external fault, enabling quick and visual troubleshooting.

• Robust Isolation: Features high isolation ratings ($2500 \text{ Vrms}$ Group to Bus) to protect the PLC backplane from voltage spikes and noise from the field wiring.

• Standardized Integration: Designed for rack mounting, allowing for easy integration and replacement within existing Modicon Quantum systems.

⚠️ Important Considerations (Notes)

• Positive (Sink) Logic: The module is a sink input module (sometimes referred to as current-sinking or positive logic). This means the external device provides a positive voltage to the module, and the module internally connects the common terminal to the PLC’s power ground (or negative side). Ensure your field devices are wired as sourcing outputs to match the module’s sinking inputs.

• End-of-Life Status (Discontinued): Note that the Modicon Quantum platform is an established product line, and this module may have been marked for discontinuation (End-of-Life) as of December 31, 2022, with end-of-service planned for December 31, 2030. When purchasing, check the availability and warranty status.

• Input Current: The minimum and maximum input current varies significantly based on the operating voltage (e.g., $5-10 \text{ mA}$ at $12 \text{ V DC}$ vs. $1-5 \text{ mA}$ at $60 \text{ V DC}$). Ensure your field devices can provide the necessary current for reliable state detection.

• Environmental Ratings: While robust, always verify that the module’s operating temperature ($\mathbf{0^\circ \text{C to } 60^\circ \text{C}}$) and humidity limits ($95\%$ without condensation) are suitable for the specific installation environment.

🏭 Product Applications

The 140DDI84100 is typically used in industrial automation and process control systems that utilize the Schneider Electric Modicon Quantum PLC platform.

• Discrete Signal Monitoring: Collecting digital status signals from process instruments and control devices.

• Manufacturing/Assembly Lines: Monitoring the state of limit switches, emergency stops, pneumatic valve positions, and part sensors.

• Building Automation: Reading the on/off status of fans, pumps, dampers, and security contacts.

• Power and Utilities: Used in substations and power control centers for monitoring breaker status and relay signals.

• General PLC Control: Any application where a high-density, reliable DC input interface is required for machine control and data acquisition.
