Product Introduction
With 24 input channels and a fast 0.7 ms response time, the Schneider 140DDI67300C discrete input module delivers reliable signal acquisition for demanding industrial environments. Part of the Modicon Quantum platform, this module handles input voltages from 88 to 150 V with a nominal rating of 125 V DC, making it suitable for a wide range of DC sensor and switch applications. The conformal coating protects against moisture and contaminants, reducing failure risks in harsh settings.

These specs ensure the Schneider 140DDI67300C maintains high noise immunity and reliable sensing in discrete control loops.
Industry Applications
Typical use cases include factory automation, material handling, and process control where 125 V DC sensors and switches are common. The fast response time (0.7 ms) suits high-speed counting or position feedback. In harsh environments, the conformal coating prevents corrosion from humidity or chemical exposure, making the module ideal for food & beverage or chemical plants.
Maintenance & Reliability
For long-term reliability, inspect the Schneider 140DDI67300C module periodically for dust accumulation and verify LED status (green for bus communication, red for external fault, and 24 green input LEDs). The conformal coating reduces the need for frequent cleaning. Ensure ambient temperature stays within 0–60 °C and relative humidity below 95% non-condensing. The module's isolation design minimizes electrical stress, extending service life in high-EMI environments.
Compatibility & Integration
The Schneider 140DDI67300C integrates seamlessly with Modicon Quantum backplanes and requires 2 input words for addressing. It works with all Quantum CPU models (e.g., 140CPU65160, 140CPU53414B) and supports standard I/O mapping. Logic is positive (sink), so wire sensors to sink current from the module. No special software configuration is needed beyond standard Quantum programming.
Selection Guide & Purchasing Advice
Before purchasing the Schneider 140DDI67300C, verify your system's bus current capacity (200 mA per module) and ensure your backplane has an available slot. This module is a direct replacement for older Quantum discrete input modules. For genuine, tested parts, consider UBEST Automation as a trusted supplier.
