Application Fields

The Kongsberg RAi-16xe is predominantly used for comprehensive sensor monitoring in marine environments:

• Propulsion Systems: Monitoring fuel oil pressure, cooling water temperature, and lubricant levels.
• Cargo Management: High-precision data acquisition for pressure and temperature in liquefied gas or chemical tankers.
• Ballast Control: Sensing tank levels and valve positions across the vessel.
• Environmental Monitoring: Collecting data from exhaust gas sensors and meteorological instruments.

 

Product Instructions

Installation of the RAi-16xe should be conducted in a clean, dry environment, typically within an IP-rated enclosure. Mount the module securely onto a 35mm DIN rail. When wiring, utilize shielded twisted pair cables for all analog inputs to minimize electromagnetic interference. The module is usually powered via the backplane or a dedicated 24V DC supply; verify polarity before energizing. Configuration of input ranges (e.g., 4-20mA vs. 0-10V) is handled through the system’s engineering workstation software. Ensure the module’s address is correctly set to match the system configuration to permit successful communication with the central processing unit.

 

Q&A: Frequently Asked Questions

Q: Does the RAi-16xe support loop-powered sensors? A: Yes, the module can be configured to provide power to 2-wire transmitters, simplifying the field wiring requirements.

Q: How does the module handle a sensor failure? A: The RAi-16xe features advanced diagnostics that detect “out-of-range” signals (such as a wire break in a 4-20mA loop) and reports an error status to the main control system immediately.

Q: Can I mix different input types on the same module? A: While the hardware supports various standards, software configuration determines the input type. Typically, channels are configured in groups or individually depending on the specific firmware version in use.
