Overview
The 140DAO84010C is a Schneider Modicon Quantum AC discrete output module, order code 140DAO84010C, providing 16 isolated outputs rated 20-132 V AC with a dv/dt of 400 V/ms. Each output is individually isolated in groups of one channel, and the module draws 1.85 W from the Quantum backplane. Conformal coating (Humiseal 1A33) protects the board in humid or dusty environments.
This module switches AC loads in the 20-132 V AC range, with a dv/dt of 400 V/ms that defines the maximum rate of voltage rise the output can handle without false triggering or damage — relevant when driving inductive loads like contactors or solenoid valves. The 16 outputs are arranged as 16 groups of 1 channel, meaning each output is isolated from the others — a fault on one channel does not pull down the rest. Internal RC filtering provides surge suppression, and an external 5 A fuse per output is recommended for overcurrent protection. Absolute maximum output is 156 V for 10 s AC and 200 V for one cycle AC, giving a transient headroom above the nominal 132 V AC. Response time is 0.5 ms, fast enough for most machine sequencing but not for high-speed counters.
Applications
As a Quantum discrete output module, the 140DAO84010C is used in medium-to-large PLC systems for switching AC loads in industrial automation — motor starters, valves, indicators, and interposing relays in process plants, water treatment, material handling, and packaging lines.
The 140DAO84010C sits in the Modicon Quantum automation platform as a standard-format AC output module. It is specified when isolated AC outputs are needed in groups of one — typical for applications requiring per-channel isolation to avoid ground loops or cross-channel faults.
The 140DAO84010C carries CE marking and is certified to UL 508 and CSA C22.2 No 142, with additional FM Class 1 Division 2 and cUL approvals for hazardous locations. Electromagnetic compatibility testing includes IEC 801-2 (4 kV contact / 8 kV air discharge) and IEC 801-3 (10 V/m radiated immunity). The module is also listed under California Proposition 65.
