Schneider Electric 140-DAO-840-00 Output Module

Schneider Electric 140-DAO-840-00 is a 16‑channel discrete AC output module for the Modicon Quantum (TSX Quantum) automation platform. It provides sixteen independent AC outputs that switch loads in the 20–253 VAC RMS range, making it suitable for controlling equipment such as lighting, heaters, or other AC devices from a Quantum controller. Each channel has an on‑state voltage drop of about 1.5 V, and outputs are organized into groups with status LEDs to indicate active channels and faults (group fuse or power condition). The module supports a rigorous safety margin, with an absolute maximum output of 300 V for 10 seconds and 400 V for a single cycle, and it includes internal protection features such as a 5 A fuse per group to help protect the I/O network.
