Description

Ex-q modules
(left)
The integrated removal device allows you to quickly install and
safely replace modules during ongoing operation if the module has
intrinsically safe front connections or no front connections.
Ex-d modules
(right)
The module is removed by means of a removal tool. See chapter
"FB Removal Tool for Ex-d Modules".

Both modules
The status of each channel is displayed using an LED. This gives
your technician clear information about the status of the field device
directly on the device itself. For more information about the status
LEDs, please refer to the respective datasheets for the modules.

Both modules
The sockets on the discharge side of the module offer 1, 2, 4 and 8
channels to connect Ex field devices.
Using the single-channel modules for controlling valves, including
feedback, two additional binary input signals can be transmitted
from the field. The portfolio is supplemented with 2-channel
modules with shutdown input for emergency shutdown.
When modules are replaced, the new module automatically adopts
the settings of its predecessor. This prevents errors when replacing
modules.
Ex-q modules
(left)
The 4-channel universal module processes analog inputs and
outputs depending on the setting. Each of the four channels can be
configured independently of the others.

Note!
All new I/O modules (Ex q) are fully compatible with the existing FB remote I/O and are
therefore ideally suited for a plant expansion. The backwards compatibility offers you the
opportunity to combine old modules (Ex d) and new modules (Ex q) on one backplane.
The IECEx certification only applies when Ex-q modules are used exclusively. The addition of
an Ex-d module nullifies the IECEx certification. The ATEX certification remains in place.
