Product Overview
The 1797-IBN16 is an Allen-Bradley Flex Ex NAMUR input module in the Flex I/O 1797 platform. It provides sixteen non-isolated sinking NAMUR-compatible inputs and installs on intrinsically-safe terminal bases (e.g. 1797-TB3 or 1797-TB3S). It is intended for hazardous-location control systems to monitor field sensors in industrial processes where intrinsic safety and NAMUR input signaling are required.
Best Suited For
- Hazardous-location NAMUR sensor monitoring
- Intrinsic-safety Flex Ex Distributed I/O systems
- Distributed input acquisition in Class I/II/III Division 1 or Zone 1 areas
- Use with 1797-TB3 or 1797-TB3S intrinsically safe terminal bases
- Flex I/O configurations requiring NAMUR inputs
