Overview
The 140DAI55300 is a Modicon Quantum VAC discrete input module that packs 32 inputs into a single slot, accepting 115 VAC nominal with a continuous ceiling of 132 V and a 200 V 1-cycle surge tolerance. It draws 10.9 W from the backplane, presents a 12 kΩ input impedance, and switches at a 4.9 ms response time, carrying CE, cUL, and FM Class 1 Division 2 certifications.
Compared to the 140DAM59000, which provides 16 discrete inputs in two groups of 8 with a 12 kΩ impedance, the 140DAI55300 doubles the input count per slot at 32 points but uses a slightly lower 12 kΩ impedance, meaning the 140DAM59000 draws less current per input for the same 115 VAC line.
