Schneider Electric 140-DDO-353-10 Digital Output Module

Schneider Electric 140-DDO-353-10 Digital Output Module is a 32-channel digital output module for Modicon Quantum controllers, delivering 24 V DC outputs with negative-logic (sink) operation. Configured as four banks of eight outputs (4x8), the module can switch loads up to 0.5 A per channel, enabling compact control of relays, contactors, solenoids, indicators, and other 24 V devices. It plugs into the Quantum I/O backplane (X80) and uses the standard Modicon Quantum bus to synchronize with the PLC's scan cycle. The 140-DDO-353-10 is rated for safety certifications including UL 508, CSA/CUL, and CE, and is specified for an operating range of 0 to 60 C. This digital output module is designed for reliable, high-density discrete control in industrial automation, providing true sink outputs that pull the connected loads to 0 V when active, with 24 V DC power supplied to energize the loads.
