Features:
- Eight independently configured input channels accept the documented voltage and current signal ranges.
- A 256-microsecond all-channel conversion supports responsive process-value acquisition in FLEX I/O systems.
- Range selection, underrange status and 16-bit two's-complement data are exchanged through the FLEX I/O image.
The Allen-Bradley 1794-IE8 is a FLEX I/O Series B analog input module with eight single-ended, nonisolated channels. Each channel can be configured for 0–10 V, ±10 V, 0–20 mA or 4–20 mA signals, and the module converts all eight channels in 256 microseconds.
Manufacturer reference: Rockwell Automation publication 1794-IN100E-EN-P and the official 1794-IE8 product record.
Exact-model verification and sourcing support are available for 1794-IE8.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Configure each channel for 0–10 V, ±10 V, 0–20 mA, 4–20 mA or Off. Save the original configuration word and verify the sign, engineering scaling and underrange handling before the replacement is returned to service.
Use keyswitch position 3 and a supported 1794 terminal base. Preserve channel commons, optional terminal-base transmitter power, shield grounding and the separation between analog and digital power supplies.
Input words 0 through 7 carry the eight analog values. Word 8 reports channel underrange bits, while the configuration word holds the range-select and full-range bits for each input.
