Schneider 140DDO84300C

Product Overview

The Schneider Electric 140DDO84300C is a high-density discrete output module from the Modicon Quantum series of Programmable Logic Controllers (PLCs). Designed for use in large-scale automation systems, this module provides 16 individually controllable discrete DC outputs capable of switching loads across a wide range of DC voltages.

Built with durability, responsiveness, and ease of integration in mind, this module is often selected for critical industrial environments that require precise digital output control—such as in manufacturing lines, infrastructure systems, and utilities.

Each of the 16 output channels can drive external devices such as contactors, relays, solenoids, or pilot lights. The module’s two banks of 8 outputs each are individually fused and electrically isolated for safety and operational integrity. The 140DDO84300C was engineered to meet the rugged standards of continuous industrial service.
