Overview
The 140DAO84010 is a Schneider Modicon Quantum AC discrete output module delivering 16 isolated outputs, each rated 20-132 VAC, with a per-module continuous current of 16 A rms and a per-point group limit of 4 A rms across four points. It carries a dv/dt of 400 V/ms, internal RC filter protection, and draws 1.85 W from the backplane. Certifications include UL 508, CSA C22.2 No 142, FM Class 1 Division 2, and CE marking.
The 400 V/ms dv/dt rating sets the maximum rate of voltage rise the output triacs can commutate without false triggering — critical when switching inductive loads like contactors or solenoid valves. Stay under this slope by adding a snubber across the load if the switched circuit exceeds the limit. Per-point current is limited to 4 A continuous for any group of four outputs, with a 16 A module total. The off-state leakage climbs with applied voltage: 1 mA rms at 24 V, 1 mA at 48 V, 2 mA at 115 V — factor this into load impedance when driving high-impedance inputs.
