Bulletin 1797 FLEX Ex™ Intrinsic Safety (IS) I/O couples the benefits of our FLEX™ I/O platform with IS technology. This lets you distribute I/O throughout hazardous areas with a single or redundant fiber or coax cable, virtually eliminating standalone IS barriers and isolators, enclosures, long wiring runs, and cable trays. FLEX Ex I/O communicates with your control system over a ControlNet™ network. It is compatible with standard FLEX I/O and communication modules for added flexibility in network choices and system configuration.

Features

• Installs into hazardous areas (Zone 1) without purged or explosion-proof enclosures
• Provides a ControlNet-based solution in the hazardous area using ControlNet™ Ex products
• Modular design lets you independently select the I/O, termination style and network interface
• Assembles without tools—all Components snap onto a DIN rail and plug together to form the I/O system
• Mounts horizontally or vertically on a standard DIN rail
• Removal and Insertion Under Power (RIUP) lets you replace modules and make connections in the hazardous area while the system is in operation
• Simplified engineering drawings, documentation, and site certification speed commissioning
