Product Specifications

Introduction Remote I/O systems, consisting of I/O modules, adapters, power supplies, and a

chassis, form the interface for signals to be transmitted from the explosion

hazardous area (Ex area), to the safe area (non-hazardous area). With

appropriate enclosures, remote I/O systems can be installed in Gas-Ex areas of

Zone 1. Using remote I/O, a wide range of digital and analog sensors and

actuators can be connected to process control systems over a EtherNet/IP™.The

adapter is the interface between the I/O modules on the chassis and the process

control system. Power supplies are used topower the I/O modules and adapter.

This manual sets out how to work with the hardware. See the adapter and I/O

modules for information on the configuration of the adapter and the I/O

modules.

Enclosures Enclosures protect all electronic components against environmental influences

and are an integral part of explosion protection. Enclosures are not part of the

Ex I/O components. In order to meet zone 1 mounting requirements, you

must use a certified enclosure, for example, ATEX for use in Europe.

Chapter 1 Product Specifications

Rockwell Automation partners with Pepperl+Fuchs for enclosure solutions.

For more details on the enclosures from our partners, see publication 1718-

PP002.

These enclosures are made of glass fiber reinforced polyester or stainless steel

and are available in various versions. The enclosures contain chassis for the

connection of modules. The modular concept allows multiple enclosures to be

flanged together to create the required expansion level. Each enclosure

contains Ex-e terminals for power. For safety, these are individually equipped

with protective covers (IP30) and touch protection.

The enclosures are equipped with a rating plate listing all safety-relevant

information, for example, type of ignition protection, temperature class,

permissible ambient temperature and permissible power.

Enclosures for Use in Zone 1

Zone 1 explosion protection relates to:

• Responsibility

•Accountability

• Safety for life, health, and property

• Electrical safety

To choose an enclosure from an enclosure manufacturer, make sure that the

manufacturer has adhered to regional certification directives, for example

ATEX for use in Europe, submitted the enclosure for regional certification in

accordance with applicable directives, such as ATEX directive 2014/34/EU,

and received appropriate certification.

The enclosure manufacturer, the manufacturing facility, and the enclosure

installer need respective certification in order to comply with regional Zone 1

standards, for example ATEX in Europe.

Chassis Function

The modules are plugged into the chassis, which in turn is installed in a

certified enclosure. The chassis supplies the modules with energy and provides

internal wiring.
