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.

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.

The status of each channel is displayed using an LED indicator for clear
information about the status of the field device directly on the device itself. For
more information about the status LED indicators, see the respective
datasheets for the modules.
When modules are replaced, the new module automatically adopts the settings
of its predecessor. This prevents errors when replacing modules.
The 4-channel configurable input/output module processes analog inputs or
outputs depending on the setting.

Digital Output Module Selection Guide
There are two digital output modules available to support different power
requirements of connected devices:1718-OB2 and 1718-OB2L.
The digital output modules can be configured to use the two channels
separately and independently or to combine the two outputs to one logical
output with more power. When the module is operating in the latter
configuration, referred to as "Parallel," the LED labeled "M" on the front of the
1718-OB2 or 1718-OB2L will be illuminated. In the Add-on Profile, the two
modes are referred to as "Low Current, Two Points," and, "High Current, One
Point."
When the module is used with two separate channels, the
1718_19_DO2_Diag:C:0 configuration assembly should be used for the
configuration data. In this case, the 1718_19_DO2:O:0 has to be used as
output assembly and the 1718_19_DO2_Diag:I:0 has to be used as input
assembly for read back and status information.
When the module is used in Parallel mode, with the two outputs combined to
one logical channel, the1718_19_DO1_Diag:C:0 configuration assembly
should be used for the configuration data. In this case, the 1718_19_DO1:O:0
has to be used as output assembly and the 1718_19_DO1_Diag:I:0 has to be
used as input assembly for read back and status information.

Product Specifications Chapter 1
Design and Dimensions of the Modules
The 1718 Ex I/O system is designed in such a way that each I/O module can be
connected to any slot in the I/O section of the chassis. The slots on the chassis
are limited so the total number of I/O that the chassis base can accommodate
varies depending on the combination of narrow and wide I/O modules. For
example, a base chassis can accommodate max. 20 narrow or 10 wide
I/O modules.
Power supplies and adapters are assigned to fixed slots. To avoid confusion,
these are mechanically coded so that they only fit in their respective slots.
Adapters and power supplies are always wide modules.
Both the I/O modules and the adapters and power supplies are equipped with
LEDs on the front that display the device status.
The I/O modules have connections on the front to which the relevant field
devices are connected. On the back of the I/O modules there is mechanical
coding that prevents an I/O module from being accidentally inserted into a
slot that is intended for an adapter or a power supply.

Product Specifications Chapter 1
Adapter Adapters form the interface between the I/O modules and the process control
system using EtherNet/IP. The adapter can be operated directly using the
touch screen on the front, meaning it can be configured directly in the field. In
addition, the device status displays using the four LEDs below the touch
screen.
The two Ethernet interfaces on the front connect the device to the Ethernet
network.
Function
An adapter can control up to 40 I/O modules and transfers their signals across
EtherNet/IP. The adapter converts the protocol of the bus that is integrated in
the backplane to the protocol of EtherNet/IP.
WARNING: Explosion hazard in Zone 1.
When pulling out an M12 connector in Zone 1, a spark may form that ignites an
explosive mixture.
• Do not pull out M12 connectors in potentially explosive atmospheres.
• Use only original Rockwell Automation cables with the 1718-AENTR.
WARNING: Property damage due to incorrect terminal assignment.
Incorrect terminal assignment and incorrectly positioned plug-in jumpers can
cause damage to the adapter.
• Ensure that the terminal assignment of the adapter is correct. See the
chassis information in the 1718 Ex I/O Installation Instructions, publication
1718-IN001. Terminals 39 and 40 must be inserted.
• Ensure that the plug-in jumper is correctly positioned. See the chassis
information in the 1718 Ex I/O Installation Instructions,
publication 1718-IN001.
IMPORTANT The total power consumption of the selected modules on each rack must not
exceed the maximum power that is supplied by the selected power supply
module configuration.
