Perth, Australia – March 2026 – Rio Tinto Iron Ore has announced a 16% increase in iron ore production and 23% lower equipment failure rates after deploying the ABB AI03 input module across its West Angelas mine in Western Australia. The upgrade, completed in Q4 2025, addressed critical reliability issues in the mine’s material handling system—where legacy modules failed in dusty, humid conditions and provided delayed equipment health data, causing 92 hours of annual production downtime and $410,000 in lost revenue.
The Challenge: Harsh Conditions and Unplanned Equipment Failures
Prior to adopting the ABB AI03, Rio Tinto’s West Angelas mine faced three major operational challenges:
- Dust and Humidity Damage: The mine’s iron ore processing plants generate high levels of fine dust, while monsoon season brings 85% humidity. Legacy modules corroded or short-circuited, requiring replacement every 6–8 months at $12,000 per module.
- Delayed Equipment Health Alerts: Old modules took 30 seconds to transmit vibration and temperature data from conveyor motors and crushers. This delay meant critical issues (e.g., bearing overheating) were detected too late, leading to catastrophic failures.
- Power Supply Instability: Remote mining sites experience frequent voltage fluctuations (±20%). Legacy modules shut down during these fluctuations, causing 15–20 production pauses per month.
“Mining is a 24/7 operation—we can’t afford modules that fail in dust or miss equipment warnings,” said James Mitchell, Rio Tinto’s Mine Operations Manager. “We needed a rugged, reliable input module that could withstand our harsh environment, send data instantly, and handle power swings without shutting down.”
ABB AI03 Input Module: The Rugged Workhorse for Mining Operations
After evaluating competitors from Schneider Electric and Eaton, Rio Tinto selected the ABB AI03 for its durability, fast data transmission, and power stability:
- Extreme Environmental Resistance: IP66/IP67-rated housing (dust-tight and waterproof) with corrosion-resistant aluminum alloy construction. Tested to withstand 100g/m³ of dust and 95% humidity, with a service life of 5+ years in mining conditions.
- Real-Time Equipment Monitoring: 10ms data transmission latency (30x faster than legacy modules) delivers instant alerts for motor vibration, bearing temperature, and crusher load—enabling predictive maintenance.
- Wide Power Input Range: Operates on 10–30V DC power, with built-in surge protection (up to 4kV) to handle voltage fluctuations. No more production pauses from power swings.
- 12-Channel Flexibility: 8 analog and 4 digital input channels monitor conveyor speed, crusher load, dust levels, and equipment temperature—all from a single module, reducing installation complexity.
- Mine-Specific Certifications: Complies with IECEx and ATEX Zone 2 standards for use in hazardous mining environments, ensuring safety and regulatory compliance.

“The AI03 has proven itself in one of the harshest mining environments on Earth,” Mitchell said. “We’ve gone from replacing modules every few months to zero failures in four months, and the real-time alerts have prevented three major equipment breakdowns. It’s directly contributing to our production targets.”
Sarah Williams, ABB’s Global Product Manager for Mining Automation, highlighted the AI03’s design philosophy: “Mining operations demand equipment that’s built to last, not just perform. The AI03 combines ruggedness with intelligence, helping miners reduce downtime, improve safety, and boost productivity—even in the toughest conditions.”
Rio Tinto plans to deploy the ABB AI03 across three more Australian iron ore mines by 2027, targeting a group-wide 12% increase in production and 20% lower maintenance costs.
