Overview
The 140DDO35300C is a Schneider Modicon Quantum automation platform DC discrete output module, providing 32 positive-logic (source) outputs at 24 V DC with a switching current of 16 A. Internal protection uses a 5 A fuse per group; the module carries CE marking and is certified to UL 508 and CSA C22.2 No 142.
This module occupies 2 output words in the Quantum backplane and drives 32 discrete loads — solenoids, contactor coils, indicator lamps — from a single 24 V DC field supply. Positive logic (source) means the output transistor switches the positive side of the load; the return is common. Each output point is fused at 3 A, with a group fuse rated 5 A per group. The absolute maximum output withstands a 56 V decaying pulse for 1.3 s, giving headroom for inductive kickback from small relays and valves. Isolation between groups is rated 500 Vrms DC for 1 minute. Response time is 1.0 ms, fast enough for most discrete sequencing in packaging, material handling, and conveyor logic. The module draws 1.75 W from the backplane.
Applications
The 140DDO35300C is used in Modicon Quantum-based control systems for machine and process automation — packaging lines, conveyor systems, water treatment skids, and OEM machinery — where a dense bank of 24 V DC sourced outputs is needed to drive contactors, solenoid valves, and pilot lights.
Within the Modicon Quantum range, the 140DDO35300C is a standard-format 32-point source output module, specified when the application requires positive-logic switching and group-level fuse protection. It sits alongside sink-logic and isolated-output variants, giving the panel builder a choice based on field device commoning and fault isolation strategy.
