Allen-Bradley FLEX HART-enabled Isolated
Analog 8-Input Module, Extreme Environment
The Allen-Bradley FLEX 1794-IF81HNFXT HART-enabled isolated analog 8-input module for extreme
environments is an enhanced version of the current 1794-IF81H module. It can operate at temperatures
between minus 25 C to 70 C and includes a modified input filter, conformal coating and is RoHS-compliant.
It has eight isolated input channels with an independent HART modem per channel. It is also HART 7.0
compliant with the exception of multidrop and burst mode support. It has new capabilities such as dynamic
run-time control of HART communication and auto-configuration of a HART device with user-supplied PV
damping, PV upper- and lower-range values and PV units code.
