FAQs

Q1: What is the primary function of the 140DAI55300?

It is a 32-channel discrete AC input module for the Modicon Quantum PLC system. It receives 115V AC signals from field devices (limit switches, pushbuttons, sensors) and converts them into logic-level signals that the Quantum processor can read and act upon.

Q2: Is the 140DAI55300 still in production?

No. The module was phased out on November 1, 2020. It is now available only as a spare part through aftermarket suppliers and the used/refurbished market. The official replacement is the BMXDAI1604 from the Modicon X80 platform.

Q3: How many input channels does this module provide?

The 140DAI55300 provides 32 discrete input channels, organized into 4 groups of 8 channels each. Each group is isolated from the others and from the bus, providing 1780 Vrms isolation for 1 minute.

Q4: What are the voltage thresholds for logic state detection?

• State 1 (ON): 79–132V AC guaranteed (57–63 Hz); 85–132V AC guaranteed (47–53 Hz)

• State 0 (OFF): 0–20V AC guaranteed
  This ensures reliable detection across the 47–63 Hz frequency range.

Q5: What are the common applications for this module?

Typical applications include industrial automation and process control, manufacturing lines, water treatment facilities, power generation, and any legacy Modicon Quantum system requiring 115V AC discrete input monitoring.
