About Allen-Bradley 1794-IE12 FLEX I/O Analog Input Module | 12 single-ended, non-isolated inputs (Voltage/Current), 16-bit resolution, 1794 distributed assembly component, 24V DC field power, IP20 modular instrumentation slice
Streamline your dense field instrumentation wiring with the high-capacity Allen-Bradley 1794-IE12 FLEX I/O Analog Input Module. Purpose-built to function as a space-saving slice card within the modular 1794 distributed assembly, this 12-channel high-density frontend digitally processes continuously variable signals from process indicators, temperature transmitters, flow meters, and pressure gauges. The hardware accommodates flexible industrial arrays by providing software configuration capabilities selectable in pairs, allowing you to seamlessly map inputs across standard current thresholds (0 to 20 mA or 4 to 20 mA) and voltage boundaries (0 to 10V DC, 10V DC, 0 to 5V DC, or 5V).
Powered by a sharp 16-bit successive-approximation digital converter (DAC), the card delivers smooth signal acquisition with a rapid conversion cycle of just 8.0 ms across all active channels. It runs on a nominal 24V DC field input stream while pulling 80 mA of backplane current down the central 5V DC Flexbus lane.
Critical Mechanical Requirement: Because this high-density module relies on single-ended, non-isolated architecture sharing a voltage common path, it must be paired with a 1794-TB3G or 1794-TB3GS ground-plane terminal base. Standard terminal bases (like the basic 1794-TB3) do not possess the required internal chassis ground configurations or additional V-common terminals to terminate these high-density loops cleanly. Set to keyswitch position 3 on the terminal base for correct alignment, this module routes data via an upstream network adapter (such as the 1794-AENTR), slashing your back-panel copper footprint while keeping multi-loop cabinet scalability effortless.
