1.Product Overview
The Allen-Bradley 1794-IB10X0B6/A FLEX I/O™ Safety Hybrid Module integrates 10 digital inputs and 6 solid-state safety outputs in a single IP67-rated package for SIL 3/PLe safety systems. Designed for Rockwell’s FLEX platform, its epoxy-potted housing (–40°C to +70°C) withstands high-pressure washdowns, oils, and corrosive chemicals while providing 250V AC reinforced isolation between I/O groups. Features dual-processor architecture with cross-monitored diagnostics, enabling <20ms safety response times. Integrated LED per-channel diagnostics and electronic keying prevent misconfiguration in GuardLogix® systems via Studio 5000®. Certified for Category 4/PL e applications without external relays.
