Profinet / EtherNet-IP Deterministic Networks and I/O Density Scaling
The 1797-IE8NF module is designed for distributed industrial I/O architectures using the Flex I/O 1797 platform. Its eight-channel analog input density allows integration of multiple current signal loops within a single hazardous-area I/O assembly. The module supports configurable data formatting and maintains deterministic data exchange through the connected control architecture.
The integrated noise filter processes external analog signals before conversion, reducing the impact of electrical interference on measurement channels. The module provides isolated-area compatibility through Ex-rated input protection, supporting Class I, II, III Division 1 and 2 hazardous location requirements.

A: The 1797-IE8NF module is designed for use with 1797-TB3 and 1797-TB3S terminal bases.
Field Installation Guidelines
Install the module using the specified Flex I/O terminal base assembly and verify correct keyswitch positioning before applying power. Field wiring should follow industrial control panel practices, including separation of analog signal conductors from high-voltage switching conductors.
Use shielded instrumentation wiring where required by the application, with cable shields terminated according to the grounding method defined for the control system. Confirm hazardous-area wiring requirements before connecting Ex-rated field circuits.
Verify that the connected analog transmitters operate within the specified current input range and that field-side power loading remains within the module electrical limits. Check fault indicators after installation to confirm correct channel operation and field wiring status.
