<h2>Overview</h2>
<p>The <strong>Schneider 140DDO35300</strong> is a 32-point solid-state discrete DC output module designed for Modicon Quantum programmable logic controllers. This module provides high-density digital output capabilities with 24 V DC nominal voltage and positive-logic (sourcing) outputs configured in 4 groups of 8 channels. Built for reliability in demanding industrial automation environments, the 140DDO35300 delivers precise output switching for control of solenoids, motor contactors, indicator lights, and other discrete load devices.</p>
<h2>Key Features</h2>
<ul>
<li><strong>32 Discrete DC Outputs</strong> — organized in 4 groups of 8 channels for flexible load distribution</li>
<li><strong>24V DC Nominal Voltage</strong> — wide input range 19.2–30 V DC accommodates typical industrial supply variations</li>
<li><strong>Fast Switching Speed</strong> — outputs switch in ≤1 ms, enabling responsive control loops</li>
<li><strong>Protected Circuits</strong> — internal fuses (5 A per group, 3 A per point) and loss-of-field indication protect connected loads</li>
<li><strong>Status LEDs</strong> — 32 green output status LEDs plus red fault and green bus indicators for easy troubleshooting</li>
<li><strong>Surge Capacity</strong> — supports 5 A surge for 0.5 ms per channel, useful for inrush-heavy loads</li>
</ul>
