   Advantages & Features

   • Cost-efficient installation: Two-wire loop powering reduces wiring and installation cost; suitable for hazardous-area mounting.

   • User-friendly interface: Menu-guided operation, intuitive Smart-Keys and dual-display (primary measurement + secondary selectable) simplify setup and calibration.

   • Modern communication options: Supports analog output and digital protocols (HART, FF, PROFIBUS PA) allowing integration with advanced automation systems.

   • Robust industrial design: High-protection enclosure (NEMA 4X / IP65), explosion-proof or intrinsically safe versions available for harsh environments.

   • Sensor compatibility: Accepts a wide variety of pH, ORP and ion-selective sensors, including ABB’s own and many third-party sensors, providing flexibility.

   • Advanced diagnostics: Continuously monitors itself and sensor status (e.g., broken electrode, high reference impedance, cable faults) and provides fault notification and remote diagnostics via fieldbus.

   • Flexible calibration: Supports both one-point and two-point calibration; during two-point calibration the analog output can be held at a defined level.

   • Noise suppression: Adjustable damping allows for smoother output in noisy process environments.

   Typical Applications

   • Water and wastewater treatment: pH/ORP monitoring is critical for neutralization, disinfection, effluent compliance.

   • Chemical industry: Acid/base processes, reaction vessels, ion-specific measurement (pIon) in manufacturing.

   • Power generation & utilities: Monitoring pH/ORP in boiler feed-water, cooling circuits, flue gas desulfurization systems.

   • Pulp & paper industry: pH/ORP monitoring in pulp bleaching stages, dye/waste liquor treatment.

   • Food & beverage / pharmaceutical: Clean-in-place (CIP) loops, pH control in production, ion monitoring where required.

   • Heavy industry: Metal finishing, plating, mining operations where pH/ORP/ion measurements are required.

   Precautions / Notes

   • Ensure power supply voltage is within specified range (14–53 VDC, or 14–42 VDC for certified versions) to avoid communication/output issues.

   • For digital communication versions (HART/FF/PA) carefully follow wiring and bus architecture rules (termination resistors, isolation, etc.).

   • Sensor selection/installation is critical: for pH/ORP sensors ensure reference electrode is intact, ground rod present to avoid ground-loop errors or diagnostic alarms.

   • In high-electrical-noise or lightning-prone environments, use properly shielded cable, good grounding and take advantage of built-in lightning suppressor.

   • Regular calibration and sensor maintenance are recommended to maintain measurement accuracy and reliability.

   • Avoid installation in extreme ambient conditions beyond the rated –20 °C to +60 °C or prolonged exposure to condensation/humidity exceeding spec.

   • When installed in hazardous zones, confirm that the model carries the required certification (e.g., ATEX Zone 1, Group IIC) and use appropriate barriers or intrinsically safe wiring as applicable.
