Product Overview
The Schneider Electric 140AIO33000 is an intrinsically safe analog output module from the Modicon Quantum series. It delivers 8 output channels with ±0.2% accuracy at 25°C, making it a practical choice for precise control in hazardous areas. This module suits zone 20, 21, or 22 destinations and carries CE and II1 G/D-EEx ia IIC marking. For oil, gas, and industrial automation teams, it offers a reliable way to drive analog loops without compromising safety.

Technical Specifications
Accuracy and Stability
The 140AIO33000 holds ±0.2% of full scale at 25°C. Accuracy drift stays at 40 ppm/°C, with a secondary limit of ≤70 ppm/°C. That means fewer calibration headaches as plant temperatures swing. Linearity is ±1 LSB, so output signals track commands tightly.
Speed and Response
Update time is 4 ms, and setting time reaches 1 ms to ±0.1% of final value. For fast control loops, that speed reduces lag and improves process efficiency.
Output and Loop
Eight analog outputs support 0…20 mA, 0…25 mA, and 4…20 mA ranges. Maximum loop resistance is 500 Ohm. An internal fuse protects the module from overloads. Power dissipation is 12.5 W, and bus current requirement is 2.5 A.
Environmental and Safety
The module operates from 0…60°C and stores from -40…85°C. Relative humidity up to 95% without condensation is acceptable. It resists electrostatic discharge at 4 kV contact and 8 kV air per IEC 801-2, and electromagnetic fields at 10 V/m from 80…2000 MHz per IEC 801-3. Operating altitude is up to 5000 m. Isolation between channels and bus is 1780 Vrms for 60 s AC. Hot swapping is not allowed per intrinsic safety standards.
Cost-Efficiency in Hazardous Areas
Every spec on the 140AIO33000 ties back to cost and uptime. The ±0.2% accuracy cuts product waste in batch processes. The 40 ppm/°C drift keeps loops stable without frequent trims. Fast 4 ms updates reduce cycle time. The internal fuse protects the module from overloads, avoiding unplanned replacement costs. For plants running Modicon Quantum, this module is a practical way to add safe analog control without a full system overhaul.

Integration and Compatibility
The 140AIO33000 works with Concept V2.2 and above, ProWORX, and Unity Pro software. It integrates into Modicon Quantum automation platforms. When wiring into fieldbus networks, you may need an external gateway or connection module. Confirm cables and gateways with your supplier before installation. The module is certified for hazardous location Class 1, Division 1, Groups A, B, C, and carries SIRA 02ATEX2345X, C-Tick, and FM Class 1 Division 2 approvals. It meets UL 508, CSA C22.2 No 142, EN 50020, EN 50014, ATEX 94/9/EC, EN 50039, EN 50281-1-1, and EN 50284 standards.
Selection and Availability
Before ordering, verify your system uses Modicon Quantum and that your application falls within zone 20, 21, or 22. Check that your loop resistance stays under 500 Ohm. The 140AIO33000 weighs 0.3 kg and uses a standard module format. Please verify current lifecycle status and availability with Oil AutoTech before ordering.
