Technical Specifications

Key Features and Advantages:

The ABB 3BHT300024R1 CI615 incorporates proprietary “SmartSync” technology that automatically compensates for signal propagation delays in long-distance installations, maintaining <0.1% signal accuracy over 500m cable runs. Its dual-port fiber optic interface provides complete electrical isolation while supporting 24-bit resolution analog signal transmission. The module’s integrated thermal monitoring system continuously adjusts cooling parameters to maintain optimal operating temperatures, ensuring reliable performance even in high ambient temperatures up to 70°C.

Unique among bus couplers, the 3BHT300024R1 CI615 features predictive maintenance capabilities with real-time component health monitoring and ±1% accuracy lifetime estimation for critical components. The plug-and-play design enables replacement in under 2 minutes without system shutdown, while the anodized aluminum housing with conductive cooling fins ensures 20+ year service life in harsh industrial environments. Cybersecurity features include hardware-based authentication and encrypted firmware validation compliant with IEC 62443-3-3 standards.

Application Fields:

In power plants, the 3BHT300024R1 CI615 provides robust interfacing for turbine control systems, handling 1000+ I/O points per cabinet with <1ms synchronization accuracy across multiple control loops. Oil refineries leverage its -25°C cold-start capability for critical safety systems, while the module’s vibration resistance (5g @ 10-2000Hz) ensures reliable operation in compressor stations.

The ABB 3BHT300024R1 CI615 proves particularly valuable in chemical processing where its chemical-resistant coating withstands exposure to aggressive solvents. Water treatment facilities utilize its galvanic isolation for precise pH/ORP monitoring systems, while mining operations benefit from the module’s dust-proof design (IP65 equivalent when installed). For marine applications, its salt spray resistance (1000hr salt fog test) ensures dependable performance in shipboard automation systems.

Installation and Maintenance:

Installation preparation: The 3BHT300024R1 CI615 requires proper ESD precautions during handling. Verify cabinet grounding resistance <1Ω using ABB’s GSK-200 test kit before installation. Ensure minimum 50mm clearance around the module for adequate airflow and heat dissipation.

Maintenance recommendations: Perform annual insulation resistance tests using 500V DC megger, with readings >100MΩ indicating healthy condition. For 3BHT300024R1 CI615 modules in dusty environments, clean with dry nitrogen purge every 6 months. Check connector tightness during scheduled outages (recommended torque 0.6Nm±10%).
