Schneider Electric 140DDO35310 Sink Output Module

Schneider Electric’s Modicon Quantum 140DDO35310 is a 32-channel discrete output module that provides 24 V DC sinking (negative logic) outputs for Modicon Quantum I/O backplanes. Configured as a 4x8 bank, it enables direct control of 24 V DC devices by having the PLC sink current through the module when an output is energized; loads are wired to +24 V and return via the corresponding sink channel to 0 V. This high-density sink output module integrates with Schneider Electric’s Quantum architecture, sharing the same addressing and diagnostics as other Quantum I/O modules for straightforward mounting in compatible racks. Typical applications include energizing relays, contactors, indicator lamps, and other 24 V DC actuators in manufacturing lines, material handling, and process control setups where compact I/O is required. The part number 140DDO35310 uniquely identifies this 32-output, sink-type variant within the Schneider Electric Modicon Quantum family, delivering reliable, field-proven performance in industrial automation environments.
