The Allen-Bradley 1794-IF8IH FLEX I/O module is a HART analog module that has isolated inputs. It is compatible with the Allen-Bradley Flex I/O 1794-TB3 1794-TB3S terminal bases. It uses the Sigma-Delta conversion type and it can handle unipolar and bipolar resolutions.
The 1794-AENTRXT adapter module is an Ethernet/IP adapter module from the Allen-Bradley/Rockwell Automation Flex I/O 1794 series. It is a dual port type of Ethernet/IP adapter module. The 1794-AENTRXT Ethernet/IP adapter module allows a redundant Ethernet/IP control system to communicate with Flex I/O devices. It can be mounted on a DIN Rail and it does not need network scheduling or routing tables. The 1794-AENTRXT Ethernet/IP adapter module can operate with 8 I/O modules in an extended temperature range.
