Product Overview
When your Modicon Quantum system needs reliable 230 VAC discrete input monitoring, the 140DAI75300C from Schneider Electric delivers. This 32-channel module is part of the proven Modicon Quantum automation platform and handles demanding industrial environments with ease. Its conformal coating and wide temperature range make it a practical choice for oil, gas, and heavy process applications where uptime matters.
Technical Specifications
The 140DAI75300C operates on 230 VAC and provides 32 discrete input channels arranged in four groups. Each channel draws 9.7 to 11.5 mA depending on line frequency, with a maximum leakage current of 2.6 mA. The module requires 250 mA from the backplane bus and dissipates up to 5 W. Response times range from 4.9 to 0.75 ms off-on and 7.3 to 12.3 ms on-off, scaling with the line cycle. Isolation between groups and between group and bus is rated at 1780 Vrms for one minute. The unit weighs 0.3 kg and operates from 0 to 60 °C, with storage from -40 to 85 °C at up to 95% relative humidity without condensation. It carries CE marking and meets UL 508 and CSA C22.2 No 142 standards.
Where the 140DAI75300C Fits
This module suits 230 VAC sensing tasks in Modicon Quantum racks. Typical uses include monitoring motor starters, valve position feedback, and field device status in oil and gas processing. Its conformal coating resists moisture and contaminants, which helps in washdown or humid plant areas. For automation upgrade projects, the 140DAI75300C offers a direct path to expand input capacity without changing your existing Quantum platform.
Integration and Compatibility
The 140DAI75300C works with Modicon Quantum controllers and is supported by Concept, ProWORX 32, and Unity Pro software. It communicates over the Quantum backplane, requiring 2 input words for addressing. When integrating into existing systems, confirm your rack has adequate bus current capacity and that your I/O map accounts for the 2-word addressing requirement. For field wiring, follow the manufacturer’s guidelines for 230 VAC discrete inputs.
Maintenance and Reliability
Routine inspection of input LEDs helps verify channel status. The module provides one green LED for bus communication, one red LED for external fault detection, and 32 green LEDs for input status. In dusty or humid environments, the conformal coating (Humiseal 1A33) adds protection, but periodic checks of terminal connections and cabinet conditions remain important. The 140DAI75300C is designed for long-term operation with low power dissipation, reducing heat-related wear.
Selection Checklist
Before ordering, verify your system voltage matches 230 VAC, confirm you need 32 input channels, and ensure your Quantum rack can supply the 250 mA bus current. Check that your application temperature stays within 0 to 60 °C. If you need help selecting the right module or compatible accessories, contact Oil AutoTech for hands-on technical support.
