Product Specifications
Introduction Remote I/O systems, consisting of I/O modules, gateways, bus termination
modules, power supplies, and a backplane, form the interface for signals to be
transmitted from the explosion hazardous area (Ex area), to the safe area (non-
hazardous area). With appropriate surrounding 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 fieldbus. Specific measures need to be taken to disconnect I/O
modules with Ex-e front connectors during ongoing operation. To do so,
observe the safety notices in this manual. The gateway is the interface between
the I/O modules on the backplane and the process control system. Power
supplies are used to power the I/O modules and adapter/gateway.
All components of the FB remote I/O with Ex-q protection meet the FB
concept. This simplifies the evaluation of modules from an explosion
protection point of view.
This manual sets out how to work with the hardware. Refer to the software
manual for the gateway and the I/O modules for information on the
configuration of the gateway and the I/O modules.

Field Units Field units (surrounding enclosures) serve to protect all electronic components
against environmental influences and are an integral part of explosion
protection. The enclosures are made of glass fiber reinforced polyester or
stainless steel and are available in various versions. The surrounding enclosures
contain backplanes for the connection of modules. The modular concept
allows multiple surrounding enclosures to be flanged together to create the
required expansion level. Each surrounding enclosure contains Ex-e terminals
for power and communication lines. For safety, these are individually equipped
with protective covers (IP30) and touch protection.
The surrounding enclosures are equipped with a rating plate listing all safety-
relevant information, e.g., type of ignition protection, temperature class,
permissible ambient temperature and permissible power.
Plastic enclosure
Glass fiber reinforced polyester offers a high level of mechanical protection for
both onshore and offshore plants.

Enclosure Material Availability
Modular plastic and stainless steel enclosures are available in various sizes and
designs, and custom solutions are also available. Depending on the version, the
device units comprise base, redundancy, and expansion backplanes installed in
the corresponding surrounding enclosures.

Backplanes Function
The modules are plugged into the backplane, which in turn is installed in a
plastic or stainless steel enclosure. The backplane supplies the modules with
energy and provides internal wiring.
Any I/O module can be inserted into any I/O slot, enabling a mixture of I/O
