Product Overview
The Schneider Electric 140DDI35300 is a 32-point low voltage DC discrete input module.
This module processes digital signals for the Modicon Quantum automation platform.
Engineers design this unit for high-density sensor interfacing in industrial control systems.
It features positive (sink) logic arranged across 4 isolated channel groups.
Each channel handles standard 24 V DC inputs with fast signal detection.
