Allen Bradley 1794-0B16P/A - 16-Point 24VDC Isolated Output - Industrial Automation Rugged Hot-Swap Digital Module

The Allen-Bradley 1794-0B16P/A FLEX I/O™ 24V DC Sinking Input Module delivers robust digital signal acquisition for industrial control systems. Designed for Rockwell Automation's modular FLEX platform, this 16-channel module features IP67-rated epoxy-sealed construction (-40°C to +70°C) to endure washdowns, dust, and chemical exposure. It supports 24V DC sinking inputs with built-in surge suppression (1.5kV) against inductive load spikes. Each channel incorporates optical isolation (500V AC continuous) and LED status indicators for real-time diagnostics. With Studio 5000® integration, users configure individual filter times (0.1-16ms) to eliminate contact bounce noise. Compatible with push buttons, proximity switches, and safety interlocks.
