Product Overview
When an AC discrete output module fails, every hour of downtime eats into your bottom line. The Schneider Electric 140DAO84210C from the Modicon Quantum automation platform delivers 16 AC outputs in a compact, standard-format module. It handles 100/230 V AC operating voltage and 83–253 V AC discrete output voltage, so it fits a wide range of industrial control panels without extra conditioning hardware.
This module suits oil, gas, and industrial automation systems where reliable switching and fast fault detection matter. With a net weight of 0.99 lb (0.45 kg), it saves panel space and simplifies installation. Oil AutoTech supplies ready-to-ship spares for these platforms, helping you avoid long lead times and costly production stoppages.
Technical Specifications That Drive Value
The 140DAO84210C packs 16 outputs arranged in 4 groups of 4 channels. That grouping lets you isolate faults and keep other channels running, which reduces unplanned downtime costs. Each output handles up to 3 A rms at 170–253 V and 4 A rms at 85–132 V. The module supports a maximum of 16 A rms total and 4 A rms per group.
Response time is <= 0.5 ms for both state 0 to state 1 and state 1 to state 0. Fast switching means shorter cycle times and better throughput on high-speed production lines. The 1.5 V maximum voltage drop keeps power losses low, cutting energy waste and heat buildup inside the cabinet.
Fault indication includes blown fuse and loss of field power, with one red LED for external fault detection and 16 green LEDs for input status. Maintenance teams spot problems immediately, reducing troubleshooting hours and expensive emergency callouts. Internal protection uses a 5 A fuse and an RC filter, while conformal coating (Humiseal 1A33) protects against harsh environments.

Where the 140DAO84210C Pays Off
In oil and gas terminals, this module controls motor starters, solenoid valves, and indicator lamps. The 16 outputs and 4-group isolation mean one fault does not shut down the whole panel, protecting revenue during critical transfer operations.
For water treatment plants, the wide 83–253 V AC output range handles varying supply conditions without extra regulators. That flexibility lowers engineering and spare-part costs. In manufacturing lines, the <= 0.5 ms response time supports high-speed sorting and packaging, directly improving output per shift.
Installation and Maintenance Tips
Mount the 140DAO84210C in a standard Modicon Quantum rack. Verify that the bus current requirement of 350 mA is available from your power supply. Use the addressing requirement of 1 output word when configuring the PLC. The module tolerates operating altitudes up to 16,404.2 ft (5,000 m) and relative humidity up to 95% without condensation.
For maintenance, inspect the 16 green LEDs and the red fault LED regularly. A blown fuse or loss of field power triggers the fault indication, so keep spare 5 A fuses on hand. The conformal coating resists moisture and contaminants, but periodic cabinet cleaning and thermal checks still extend service life. Oil AutoTech offers hands-on technical selection help to match this module to your existing Quantum system.
Compatibility and Integration
The 140DAO84210C belongs to the Modicon Quantum platform and works with Quantum controllers and I/O racks. It carries CE marking and certifications including cUL and FM Class 1 Division 2, with EMC immunity tested to IEC 801-2 (4 kV contact, 8 kV air) and IEC 801-3 (10 V/m). These ratings support reliable operation in electrically noisy industrial environments.
Before ordering, confirm your rack supports the standard module format and that your power supply meets the 350 mA bus current requirement. Please verify current lifecycle status and availability with Oil AutoTech before ordering.
