1794‑IE8H/B‑AO - Analog‑Signal‑Acquire/Analog‑Signal‑Output - Plastic 8Ch Flex I/O HART Analog Module
The 1794-IE8H is a FLEX I/O 8-channel HART-enabled analog input module with 16-bit resolution, 0-20 mA range, and per-channel wire-off detection. It operates on ControlNet/EtherNet/IP networks with support for one HART device per channel.
This module acquires process variables including pressure, flow, level, and temperature from HART transmitters while simultaneously reading device diagnostics—eliminating the need for a separate HART multiplexer. The compact FLEX form factor operates in -20 to +55°C environments and is hot-swappable with TB3G/TB3GS bases.
