When triggered, the red 'F' LED lights and the module signals the fault over the backplane, reducing troubleshooting time on large I/O racks. The module is conformally coated (Humiseal 1A33) for moisture and contaminant resistance, and operates from 0 to 60°C with 95% non-condensing humidity. It draws 250 mA from the Quantum backplane and requires four input words of addressing. Electrical isolation is robust: 1780 Vrms for 1 minute between the input group and the backplane, and 500 Vrms between input groups — important for preventing ground loops in long field-wire runs. The 140DSI35300C carries CE marking and is UL 508 and CSA C22.2 No. 142 listed. The documentation set includes those certifications; no separate RoHS or REACH declarations are on file in the standard record, but the unit was produced under Schneider's standard environmental compliance program.","metaTitle":"Schneider 140DSI35300C Quantum 32-input DC Module, 24 V","metaDescription":"140DSI35300C is obsolete. 32-point 24V DC discrete input module with broken wire detection, UL/CSA.
