Main Features of the 140DAI55300

• Brand & Model: Schneider Electric 140DAI55300 – genuine Modicon Quantum part.
• Inputs: 32 points, 115V AC. They come in 4 isolated groups. Each group has 8 inputs.
• ON Voltage: Module turns ON from 79 to 132V AC. It turns OFF below 20V AC.
• Current Draw: Each input uses 11.1 mA (60 Hz) or 13.2 mA (50 Hz).
• Speed: Off-On response takes 0.75 to 4.9 ms. On-Off takes 7.3 to 12.3 ms.
• Isolation: 1780V isolation between groups. Also isolated from the backplane.
• Power Use: Needs 250 mA from the bus. Dissipates 10.9 W max.
• LEDs: 32 green LEDs show input status. One green LED for bus active. One red LED for faults.
• Software: Works with Unity Pro, ProWORX 32, and Concept.

Quick FAQ

• Which software works with the 140DAI55300? It runs on Unity Pro, ProWORX 32, and Concept.
• What is the max leakage current? It handles up to 2.1 mA leakage.
• Can I use 230V with this module? No, it only works with 115V AC. Higher voltage will break it.
• Are the inputs isolated? Yes, between groups. But not between points in the same group.
• What do the LEDs tell me? Green LEDs show each input on/off. The red LED means a fault.
