Rockwell Automation debuts safe I/O modules for connections in hazardous areas

The new Allen-Bradley 1718 Ex I/O modules from Rockwell Automation allow industrial producers to connect to devices in hazardous areas.

The safe distributed I/O modules provide EtherNet/IP connectivity to field devices in Zone 0 and Zone 1 hazardous areas.

1718 Ex I/O modules can reduce wiring in industrial applications because they can be mounted in Zone 1, closer to field devices in hazardous areas.

The I/O modules can also save space with a compact, chassis-based I/O design that contains the primary power supply and an optional redundant power supply in the chassis.


Different chassis options and slot sizes allow users to scale the 1718 Ex I/O modules to meet a wide range of system requirements. Add-on profiles in the Studio 5000 Logix Designer application help ease configuration of the modules.

And a dual-port EtherNet/IP adapter that enables a Device Level Ring (DLR) topology can help improve network resilience.

The 1718 Ex I/O modules are designed for hazardous applications found in industries like chemical, oil and gas, and food and beverage.

An ATEX-certified enclosure is required for the 1718 Ex I/O modules to be mounted in an ATEX Zone 1 area.
