Product Overview
The Schneider 140DAI75300C discrete input module is a direct replacement for older, less efficient input modules in the Modicon Quantum line. Designed for 32 channels at 230VAC, this module offers a robust upgrade path for facilities looking to standardize on 230VAC sensing while reducing bus current draw and power dissipation. With conformal coating and a wide operating temperature range (0 to 60°C), the 140DAI75300C is built for harsh industrial environments.

These specs make the 140DAI75300C a drop-in upgrade for systems using lower-voltage or older Quantum modules, reducing wiring complexity and improving noise immunity.
Industry Applications
The 140DAI75300C excels in manufacturing cells, conveyor systems, and packaging machinery where 230VAC sensors are common. For example, in a bottling plant replacing a 120VAC input module with the 140DAI75300C eliminates the need for a separate transformer for sensor power, simplifying panel layout. Its 2.6 mA max leakage current ensures compatibility with older proximity sensors without false triggering.
Installation & Setup Guidance
When installing the 140DAI75300C, ensure the Quantum rack backplane delivers adequate 250 mA bus current. The module occupies one slot and requires 2 input words in the I/O map. For wiring, use twisted-pair or shielded cable for long runs (over 100 m) to minimize electrical noise. The conformal coating protects against moisture and particulate contamination, but avoid direct exposure to solvents during cleaning.
Selection Guide & Purchasing Advice
Before ordering the 140DAI75300C, verify that your Quantum rack has an available slot, and that your PLC firmware supports a 32-channel 230VAC input module. The module uses a standard 40-pin connector compatible with Quantum wiring kits. UBEST Automation stocks genuine Schneider 140DAI75300C modules with full traceability.
