Allen-Bradley 1797-IBN16

The Allen‑Bradley 1797‑IBN16 is a 16‑channel intrinsically safe (IS) digital input module from the FLEX Ex I/O family, specifically designed for hazardous environments requiring NAMUR‑compatible sensor interface. This module eliminates the need for external isolation barriers by integrating intrinsic safety circuitry directly into the I/O hardware, significantly reducing cabinet space and wiring complexity. As part of the FLEX Ex system, the 1797‑IBN16 is rated for installation in Zone 1, Zone 2, and Zone 22 (Class I, II, III, Division 1, Groups A‑G) hazardous locations, making it ideal for demanding applications in oil & gas, chemical processing, and pharmaceutical facilities.
