Discrete Input 140DDI35300 is a Modicon Quantum low-voltage DC discrete input module featuring 32 inputs at 24 V DC. It supports positive (sink) logic with input voltage range 19.2–30 V, guaranteed ON at 15–30 V and OFF at –3–5 V. The module responds within ≤1 ms, dissipates 1.7 W + 0.36 W per active point, and isolates up to 1780 Vrms (bus) and 500 Vrms (between groups). It includes an array of LED indicators (32 green for input status, red for faults, green for bus comm), requires 330 mA bus current, and is built for industrial environments (UL/C-UL, CSA, CE, and others).
