1794-OV16 - 16-Point 24VDC Isolated Output - Industrial Automation Rugged Hot-Swap Digital Module

The Allen-Bradley 1794-OV16 FLEX I/O™ Digital Output Module provides industrial-grade 24V DC control for demanding automation systems. Designed for Rockwell's distributed FLEX platform, this 16-channel module features IP67-rated epoxy-sealed construction (-40°C to +70°C) to withstand high-pressure washdowns, oils, and chemical exposure. It delivers sourcing outputs with 0.5A continuous current per channel (3A inrush for 100ms), enabling direct control of solenoids, relays, and indicators. Built-in 1.5kV surge suppression (per IEC 61000-4-5) protects against inductive kickback, while 500V optical isolation prevents ground loops. Studio 5000® integration enables per-channel diagnostics and pulsed output configurations.
