Allen-Bradley 1719-IF4HB HART Analog Input Module

The Allen-Bradley 1719-IF4HB FLEXHA 5000 Ex I/O HART Analog Input Module is a four-channel intrinsically safe HART input module for the FLEXHA 5000 Ex I/O platform, designed to monitor analog process signals and enable HART field-device diagnostics in hazardous environments. It accepts 4–20 mA process signals, provides HART device communication and diagnostics, and offers channel-to-system isolation with backplane communication on a DIN-rail mounted package. Common applications include oil and gas facilities, chemical plants, pharmaceutical systems, and other hazardous process environments requiring accurate process monitoring of pressure transmitters, temperature sensors, flow instruments, level devices, and process analyzers. LED indicators report module and channel diagnostics, and it remains compatible with the FLEXHA 5000 Ex I/O platform, with replacements including 1719-IF4B, 1719-OB2, and 1719-AENTR.
