In today’s industrial environments, combining safety with digital innovation is no longer optional—it’s essential. Industries like oil & gas, chemical processing, and mining increasingly rely on SCADA systems (Supervisory Control and Data Acquisition) to monitor and manage critical processes. But what happens when workers need mobile access to these systems in hazardous areas?
The answer lies in an intrinsically safe tablet for SCADA systems—a rugged, certified device designed for explosive atmospheres, yet fully compatible with modern industrial automation platforms.
This guide explores what to look for in these specialized tablets, how they interface with SCADA, which models stand out, and why certification is non-negotiable.
What Makes a Tablet “Intrinsically Safe” and SCADA-Compatible?
An intrinsically safe tablet is engineered to operate in environments where flammable gases, vapors, or dusts could ignite under normal electronic operation. These tablets limit the energy—both electrical and thermal—so that they cannot cause ignition, even in the event of a fault.
For SCADA compatibility, the tablet must also meet specific software and hardware requirements:
Key SCADA-Compatible Features
Operating system: Windows or Android OS that supports SCADA clients or HMI apps.
Communication protocols: OPC UA, Modbus TCP, MQTT, or other industrial protocols.
Connectivity: Wi-Fi, 4G LTE, and Bluetooth for field data acquisition.
Ruggedization: Drop-tested, IP-rated, and operable in temperature extremes.
Certifications: ATEX, IECEx, and/or Class I Division 1 or 2.
A true intrinsically safe SCADA tablet bridges the gap between mobile field work and real-time operational control.
Why Is SCADA Tablet Certification So Important in Hazardous Areas?
When working in explosive atmospheres, the safety of personnel and infrastructure hinges on device compliance. Tablets used in these areas must meet stringent international standards that define safe operation.
Common Certifications
| Certification | Region | Description |
|---|---|---|
| ATEX | EU | Certifies equipment for explosive atmospheres under European law. |
| IECEx | Global | Verifies that devices meet international standards for explosive environments. |
| Class I, Div 1/2 | North America | Covers areas where flammable vapors may be present (Class I) under Division 1 (constant risk) or Division 2 (occasional risk). |
These certifications validate that the tablet can be safely used in your work environment. Choosing uncertified or partially certified devices is never an option in regulated industries like oil refineries, chemical plants, or underground mines.
How Do Intrinsically Safe Tablets Interface with SCADA Systems?
Once deployed, these tablets become essential tools for field technicians, engineers, and operators. But how exactly do they interact with SCADA platforms?
Typical Use Cases
Monitoring: Live dashboards showing system status, alarms, and trends.
Control: Authorized users can initiate start/stop commands or change parameters.
Reporting: Automatic logging of field activities or environmental readings.
Diagnostics: Mobile access to PLC data, sensor diagnostics, and troubleshooting.
Leading intrinsically safe tablets support SCADA clients like Ignition, AVEVA, or GE Digital, either through native apps or web interfaces. By giving workers mobile access to these systems, downtime can be reduced, responsiveness is improved, and safety is heightened.

How to Choose the Right Tablet for Your SCADA Needs?
Choosing the right intrinsically safe tablet involves evaluating both environmental safety and software compatibility. Consider the following:
Key Selection Criteria
Zone Classification
Is the device certified for ATEX Zone 1 or Zone 2? Know your hazardous area rating and match accordingly.OS Preference (Windows vs Android)
Some SCADA platforms work better on Windows due to legacy drivers or software. Others may offer Android apps for simplified mobility.Battery Life and Charging Options
Long battery life is critical. Some models support hot-swappable batteries, reducing downtime.Touchscreen Usability
Ensure glove and rain compatibility for outdoor or PPE-heavy environments.Camera and Security Options
Certain industries ban cameras due to IP concerns. Choose a camera-free model like the Aegex 100M where needed.Device Size and Mounting
Larger screens help with complex dashboards, while compact tablets are ideal for one-handed use or vehicle mounting.
The best tablet is the one that balances safety, performance, and worker efficiency in your unique SCADA environment.
FAQs About Intrinsically Safe Tablets for SCADA Systems
Are all rugged tablets intrinsically safe?
No. Rugged tablets may resist water, dust, and shocks—but only intrinsically safe tablets are certified for use in explosive atmospheres. Always check for ATEX, IECEx, or Class I certifications before deploying in hazardous zones.
Can SCADA software be installed directly on these tablets?
Yes. Many intrinsically safe tablets run Android or Windows and can host native SCADA apps or client dashboards. Compatibility depends on your SCADA software provider—ensure that the required apps or protocols are supported.
What’s the difference between Zone 1 and Zone 2 certification?
Zone 1 indicates a higher likelihood of explosive gases being present during normal operations. Zone 2 is a lower-risk area where gases are present only under abnormal conditions. Zone 1-certified tablets are more robust and versatile but often cost more.
Can these tablets connect to PLCs and RTUs?
Yes. Most support protocols like Modbus TCP/IP, MQTT, or OPC UA—commonly used to communicate with PLCs and Remote Terminal Units in SCADA systems.
Do intrinsically safe tablets support cloud-based SCADA?
Absolutely. With proper connectivity (Wi-Fi, LTE), these tablets can securely access cloud-hosted SCADA platforms, enabling remote monitoring and updates in real-time.
Conclusion: Empower Your SCADA System with the Right Tablet
In a world where safety and performance must go hand in hand, an intrinsically safe tablet for SCADA systems is an indispensable tool. These rugged, certified devices not only meet the strictest safety standards but also bring the power of modern industrial automation directly into the field.
By understanding certification requirements, operational needs, and SCADA compatibility, you can select a tablet that enhances both safety and efficiency.
