The Allen-Bradley 1794-OB16P FLEX I/O™ 16-Channel Sinking Input Module provides robust digital signal acquisition in harsh industrial environments. Designed for Rockwell Automation's modular FLEX platform, this IP67-rated module features epoxy encapsulation (-40°C to +70°C) that withstands high-pressure washdowns, oils, and corrosive chemicals. It supports 24V DC sinking inputs with 1.5kV integrated surge suppression (IEC 61000-4-5) per channel, preventing damage from inductive kickback. Each input includes optical isolation (500V AC continuous) and dual-color LED status indicators (green=ON/red=fault). Tool-free 1794-TB3/B push-lock terminals enable rapid wiring, while Studio 5000® software allows configurable filtering (0.1-16ms) to eliminate signal noise.
