FLEX Ex I/O
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.

Use the Bulletin 1797 FLEX Ex™ communication module and FLEX Ex I/O installed in the hazardous area to gather data at its origin and transport it to the safe area with minimal wiring. ControlNet™ Ex connectivity leverages the diagnostic capabilities and determinism of the ControlNet network for intrinsic safety (IS) applications. FLEX Ex is also compatible with standard FLEX™ I/O communication modules for connectivity to DeviceNet™, Universal Remote I/O, and EtherNet/IP™ networks.
Bulletin 1797 FLEX Ex™ Intrinsic Safety (IS) I/O provides flexibility for your hazardous application. Use FLEX Ex I/O with a FLEX Ex communication module installed in the hazardous area to gather data at its origin and transport it to the safe area with minimal wiring. Advanced diagnostics provide real-time status for easier troubleshooting.
Bulletin 1797 FLEX Ex™ power supplies provide power for the FLEX Ex ControlNet™ Ex network, communication adapter, I/O modules, fiber hub, and intrinsic safety (IS) field devices. No other power sources are needed to operate any components attached to the FLEX Ex system in the hazardous area. Power for valves, actuators, or transmitters comes from the FLEX Ex modules.
Bulletin 1797 FLEX Ex™ terminal bases snap onto the DIN rail to the right of the communication adapter module. The terminal bases provide terminal connection points for I/O wiring and plug together to form the backplane.
