Product Description

The Schneider Electric Modicon 140DDI84100 is a high-density, high-speed Digital Input (DI) Module designed for the Modicon Quantum series of Programmable Logic Controllers (PLCs).

It functions to read and monitor the ON/OFF status of field devices such as pushbuttons, limit switches, selector switches, and proximity sensors. The module converts the external electrical signals into logical signals (1s and 0s) that the PLC’s Central Processing Unit (CPU) can process.

• Input Type: Discrete (Digital) Input.

• Voltage Range: Designed for 24 V DC applications.

• Density: It is a high-density module, minimizing the physical space required in the PLC rack.

Product Parameters

Product Advantages

• High Density: With 32 inputs in a single module, it maximizes the utilization of space within the Quantum rack, reducing the overall panel size and cost.

• Fast Response: Designed for industrial speed requirements, ensuring quick and reliable reading of input status changes, which is critical for time-sensitive control loops.

• Diagnostic Capabilities: Often includes features for diagnostic reporting to the CPU, such as broken wire detection (depending on the external wiring method).

• Robust Reliability: Built to the industrial standards of the Quantum platform, ensuring durability and high reliability in harsh environments.

Precautions

• Input Current Type: The module is strictly designed for 24 V DC signals. Connecting an AC voltage or a DC voltage outside the specified range will permanently damage the module.

• Sink/Source Logic: Verify the module’s exact wiring requirement (Sink or Source) and ensure it matches the wiring method and the type of field device used to prevent incorrect operation or damage.

• Wiring Density: Due to the high number of inputs (32), wiring must be done carefully to avoid errors. Utilize the correct terminal blocks and follow the wiring diagram strictly.

• External Power Supply: The module requires a stable and reliable 24 V DC external power supply for the field devices. Any fluctuation can lead to unreliable input readings.

Product Applications

The 140DDI84100 is widely used in complex, high-channel-count industrial automation systems:

• Assembly and Manufacturing Lines: Monitoring the status of numerous sensors, limit switches, and proximity switches on complex machinery.

• Packaging Machinery: High-speed reading of position sensors and control buttons on high-throughput packaging lines.

• Water and Wastewater: Reading status points from pumps, valves, flow switches, and level switches at distributed I/O locations.

• Energy and Utility Monitoring: Collecting digital status (e.g., breaker position, switch status) from various electrical and mechanical components.
