Schneider Electric's Modicon Quantum 140-DAO-842-10 is a 16-channel discrete AC output module for the Quantum PLC backplane. It provides 16 outputs that switch line-voltage AC loads, with an operating range of 83 to 253 VAC per point, suitable for driving relays, contactors, or other AC loads directly from the PLC I/O backplane. The module carries UL 508, CSA 22.2-142, and FM Class 1 Division 2 approvals, and is designed for integration within Schneider’s Quantum I/O architecture to support scalable, backplane-based automation.
