FOXBORO RH916XZ
Product Introduction
Maintaining optimal environmental conditions is critical for process stability, product quality, and equipment safety in industrial facilities. The is a high-precision humidity sensor designed for the I/A Series DCS. It accurately measures ambient relative humidity and seamlessly integrates this data into the control system, allowing operators to make real-time adjustments to HVAC or environmental control loops.
Engineered for demanding industrial environments, this sensor features robust anti-interference technology and a durable casing. Field engineers specify the because its fast response time and high stability ensure that critical humidity parameters are continuously monitored without signal degradation or false readings.
Key Selling Points & Differentiators
- Exact I/A Series Compatibility: Designed specifically for FOXBORO I/A Series DCS integration; not recommended for non-Foxboro control systems due to proprietary communication interfaces.
- High-Precision & Fast Response: Provides accurate, reliable humidity data with real-time response to environmental changes, ensuring tight process control.
- Robust Anti-Interference Design: Operates stably in electrically noisy industrial environments without being affected by external EMI/RFI interference.
- Versatile Installation: Supports multiple installation methods (wall mounting, hanging, or internal device mounting) to adapt to various application scenarios.
- Rigorous Live Bench Testing: Every unit undergoes a 24-hour continuous load test with humidity simulation and communication verification before shipping.
- New Surplus Availability: Factory-sealed condition with verified source traceability, bypassing typical OEM lead times for discontinued I/A Series hardware.
- Anti-Counterfeit Verification: Serial numbers are checked against manufacturer databases during incoming inspection to guarantee authenticity.

FAQ
The is designed for the I/A Series platform, but compatibility with specific sub-platforms depends on firmware and backplane revision. Always verify your system’s exact configuration and check the I/A Series hardware compatibility matrix before ordering. Mixing incompatible module revisions can cause communication failures.
I have a different RH916-series sensor on hand. Can I use it as a direct replacement?
While various RH916-series modules share a similar form factor, they are typically designated for specific measurement ranges or communication protocols. Substituting a different suffix without verifying the exact backplane compatibility and functional requirements can result in inaccurate readings or communication dropouts. Always match the exact part number.
Do I need to configure the sensor parameters before installing?
Yes. The module typically requires configuration via DIP switches or software configuration in the I/A Series control builder to define the measurement range, scaling parameters, and communication settings. I always recommend backing up your control strategy and verifying the configuration matches your system design before installation.
What happens if I install this in a highly corrosive environment?
While the features a durable casing designed for harsh industrial conditions, extreme corrosive environments may require additional protective housings or specialized sensor probes. Always verify the sensor’s chemical compatibility against your specific environmental conditions.
Is there a warranty on this new surplus unit?
Yes. All new surplus modules come with a standard 12-month functional warranty. If the unit fails during normal operation within that period, we provide a direct replacement. We also include our internal test report with every shipment so you can verify the 24-hour load test and measurement accuracy results before installation.
