EtherNet/IP and FLEX Ex I/O Integration Characteristics
The 1797-IRT8 operates as a FLEX Ex input module with internal bus configurable signal channels. The module processes RTD and thermocouple input signals within the FLEX Ex architecture and transfers acquired data through the system backplane communication path.
The module supports input signal measurement within the 40 to 100 mV range and provides an 8 ms settling time for analog acquisition response. The configurable channel structure allows application-specific temperature input selection without changing the physical module hardware.
The FLEX Ex platform supports industrial control architectures requiring modular I/O density scaling and backplane bus communication velocity management. Firmware flash compatibility should be verified against the installed FLEX Ex adapter and controller configuration before replacement or migration activities.
Frequently Asked Questions
Q: How many analog input channels are available on the 1797-IRT8 module?
A: The 1797-IRT8 provides 8 input channels configured for RTD and thermocouple signal acquisition.
Q: What power consumption value is specified for the module field-side operation?
A: The module field-side power consumption is specified as 1.6 W, with power dissipation also rated at 1.6 W.
Q: Can the 1797-IRT8 input type be changed through hardware modification?
A: The input type is configured through the internal bus configuration function. No physical hardware modification is specified for input type selection.
Field Installation Guidelines
Install the 1797-IRT8 module within the designated FLEX Ex I/O assembly according to the system installation documentation.
Use appropriate industrial wiring practices for RTD and thermocouple circuits. Maintain separation between low-level temperature measurement wiring and high-current power conductors to reduce electrical interference.
Connect cable shields according to the plant grounding standard and avoid creating multiple ground paths that may introduce signal noise.
Verify module seating, terminal connections, and backplane engagement before system power application. Confirm controller and adapter firmware compatibility before replacing an installed module.
