Schneider Electric 140DAO84000 Analog Output Module

Schneider Electric 140DAO84000 is a 16-channel discrete output module for Modicon Quantum controllers that provides direct AC switching via triac outputs. Designed for the Modicon X80 I/O bus, it enables compact, field-side control of 16 AC loads while the CPU drives the state of each channel. The module operates with a broad AC supply range of 20 to 253 V AC, letting it switch standard line-powered devices. Each of the 16 outputs is triac-based, allowing control of AC devices without requiring separate driver electronics. The 140DAO84000 is part of Schneider Electric's Quantum modular I/O family, intended to be mounted alongside compatible I/O modules in a Modicon Quantum rack, enabling scalable, distributed control. Typical applications include valve actuation, lighting, heater elements, and other line-voltage loads where discrete outputs are used to switch AC loads in industrial automation. The unit uses the X80 interface for plug-in compatibility with Quantum processors, delivering straightforward field wiring and seamless integration with Schneider Electric's control software.
