Profinet / EtherNet-IP Deterministic Network and I/O Density Scaling
The 1797-IBN16 is part of the Allen-Bradley Flex Ex I/O 1797 platform and operates as a high-density digital input module within an Ex-rated distributed I/O architecture. The sixteen-channel configuration provides I/O density scaling for hazardous-area signal acquisition while maintaining separated field wiring through compatible terminal bases. The module supports NAMUR input evaluation with selectable input delay parameters for signal conditioning in industrial control applications.
The module incorporates intrinsic safety classifications including Ex ia IIB/IIC T4 and Ex ib IIB/IIC T4 configurations. The input design supports hazardous-area device connection requirements with non-isolated sinking input circuits and defined current thresholds for NAMUR-compatible switching devices.

Field Installation Guidelines
Install the 1797-IBN16 using the specified FLEX Ex terminal base and verify that field wiring matches the NAMUR input requirements before energization. Maintain proper segregation between intrinsically safe circuits and non-IS wiring paths according to site electrical installation procedures.
Use the recommended conductor size and ensure terminal connections maintain mechanical integrity. Shielded signal cables should follow plant grounding practices, with cable shields terminated according to the control system grounding design.
Verify module power status and channel diagnostic indicators after installation. Confirm that connected field devices provide expected NAMUR current states and that input delay settings correspond to the required signal response behavior.
