Schneider Electric 140-DDO-353-01 Programmable Logic Controller Module

Schneider Electric's 140-DDO-353-01 is a Modicon Quantum digital output module that provides 32 discrete 24 V DC positive-logic outputs on the Quantum X80 I/O bus, enabling direct control of loads such as relays and contactors from a central PLC. Each output is a 24 V DC sourcing channel rated for up to 5 A, designed for use with the Modicon Quantum platform's X80 backplane and its associated I/O architecture. In Schneider Electric catalogs, the 140DDO35301 is described as a 32-output, 24 V DC positive-logic (source) module, suitable for legacy Quantum installations requiring substantial discrete output capability. The product was discontinued for commercialization on December 31, 2022, with after-sales support continuing through December 31, 2030; Schneider Electric lists BMXDDO1602 (X80, 16 outputs, 24 V DC positive logic) as a recommended replacement for this family. This module thus serves as a historical, high-density discrete I/O option within the Quantum ecosystem, and may be migrated to the X80 family in newer configurations to maintain ongoing support and compatibility with contemporary controllers.
