Product Overview
The Schneider Electric Modicon Quantum 140DAI35300 module captures 32 discrete 24 V AC field inputs.

Global PLC Spare HUB's Insight
Our field team recently troubleshot an AC input flickering issue at a municipal wastewater facility.
Long cable runs caused capacitive coupling, holding 24 V AC lines near 8 V AC during off states.
Because the Modicon Quantum 140DAI35300 guarantees a state 0 off threshold between 0 and 5 V AC, phantom voltage triggered false inputs.
Engineers installed loading resistors across the field terminals to drain the stray capacitive charge.
The 140DAI35300 module immediately resumed stable, highly accurate signal detection across all 32 channels.
Frequently Asked Questions
Question: How does line frequency affect the voltage thresholds of the 140DAI35300 card?
Answer: At 60 Hz, guaranteed state 1 requires 12 to 30 V AC. At 50 Hz, it requires 14 to 30 V AC.
Question: What happens if induced cable voltage exceeds 5 V AC on an open input point?
Answer: The channel may read a false active state. Install external loading resistors to bleed off capacitive stray voltage.
Question: How many words does the PLC processor allocate for this 32-point AC card?
Answer: The controller reserves two 16-bit input data words to read all 32 discrete AC points.
Question: What key factors should buyers verify before purchasing a 140DAI35300 replacement module?
Answer: Confirm your field power supply matches 24 V AC rather than 24 V DC or 115 V AC levels.
Question: Why does the 140DAI35300 dissipate up to 10.9 Watts of power during operation?
Answer: Internal capacitive input circuitry generates heat while filtering alternating current line fluctuations across 32 active points.
