FAQ
FAQ
Q1. What is the main function of 1797-IBN16?
It is a hazardous-area digital input module designed to read NAMUR sensors in FLEX Ex systems.
Q2. What does NAMUR mean here?
NAMUR is a standard for low-power proximity sensors, commonly used in explosion-proof (Ex) applications.
Q3. How many inputs does it have?
It provides 16 independent input channels.
Q4. What kind of sensors can it connect to?
- NAMUR proximity sensors
- Intrinsically safe switches
- Low-current industrial sensors
Q5. Is it isolated per channel?
No, it uses a non-isolated group input structure, typical for FLEX Ex designs.
Q6. Where is it used?
It is used in oil & gas, chemical plants, and other hazardous environments requiring intrinsic safety.
Q7. What is its maximum signal frequency?
Up to 1000 Hz, suitable for fast pulse monitoring.
Q8. What is its role in a FLEX Ex system?
It acts as a safe input interface between field NAMUR sensors and the ControlNet/FLEX Ex control system.
