Overview
The 140DDO35301 is a Schneider Modicon Quantum discrete output module, order code 140-DDO-353-01, providing 32 outputs in a positive logic (source) configuration at 24 V DC. It occupies 2 output words of addressing space and draws 5.0 W from the backplane. Internal protection is handled by a 5 A fuse per group, with LEDs for bus activity (green), external fault (red), and individual output status (32 green LEDs). The module carries CE, UL, CSA, and FM Class 1 Division 2 certifications.
Outputs are grouped with a 5 A fuse per group and a 3 A fuse per point, protecting against sustained overloads. Isolation between groups is rated at 500 Vrms DC for 1 minute, allowing mixed-voltage zones on the same module. Fault indication covers loss of field power and blown fuse via the red F LED, while the 32 green LEDs show individual output on/off state. The module uses positive logic (source) — outputs sink current to the common when active.
Applications
In a Modicon Quantum rack this module handles discrete DC loads such as pilot lights, relay coils, contactors, and small solenoid valves in machine control, material handling, and process skids. The 32-point density fits medium-scale I/O banks where a single module replaces two 16-point blocks.
Within the Modicon Quantum automation platform the 140DDO35301 is a standard-format 32-point source output module, specified when the control scheme requires positive-logic wiring and per-point fusing. It sits alongside sink-output (140DDO36400) and isolated-output (140DAO84220) siblings for the same rack.
The 140DDO35301 carries CE marking and is certified to UL 508 and CSA C22.2 No 142, with additional FM Class 1 Division 2, C-tick, RMRS, and GOST approvals. California Proposition 65 compliance is noted on the product documentation.
