Product Overview
When a Modicon Quantum line goes down, every hour of downtime erodes throughput. The Schneider Electric 140DDO35300C is a DC discrete output module built to keep those lines moving. It delivers 32 discrete outputs arranged in 4 groups of 8, using positive source logic for straightforward control of connected field devices. The module occupies a standard format slot and requires 2 output words for addressing.
This is a practical, ready-to-ship spare for oil, gas and industrial automation cabinets running the Modicon Quantum automation platform.

The 24V DC output stage tolerates supply swings from 19.2 to 30V DC, so real-world voltage sag on a loaded panel does not interrupt switching. Response time stays at or under 1 ms in both directions, which matters when the output drives fast-acting solenoids or interposing relays. Internal output protection uses a 5 A fuse per group, and the module reports loss of field power and blown fuse conditions through front-panel LEDs.
Where It Fits
The 140DDO35300C suits panels that need dense discrete control without adding rack space. Typical uses include driving pilot valves and solenoid banks on wellhead control panels, energizing indicator and alarm circuits in compressor stations, and switching relay coils on packaging or conveyor lines. The 4 A per-group limit lets you split loads across groups so a single fault does not take down the whole output bank.
Integration and Selection Notes
The module communicates over the Modicon Quantum backplane and requires 2 output words of addressing. Wiring into the host network may require an external gateway or connection module depending on your architecture; confirm cables and gateways with your supplier before commissioning. The unit is CE marked and carries a conformal coating (Humiseal 1A33) for protection in humid or contaminated control rooms.

Comparison at a Glance
- 140DDO35300C (this module): 32 outputs, 4 groups, 24V DC source logic, 16 A per module.
- Lower-density DC output modules: fewer points per slot, more rack space per channel.
- Higher-density modules: more points, but tighter per-group current budgets and different addressing.
- Relay output modules: handle AC and DC loads but switch slower than this module’s <= 1 ms response.
