2.2 Purpose
The SFB-PN-IRT-8M12-IOP safety fieldbox is designed for connection
of up to 8 safety switchgear units with parallel IO signals to a
PROFINET/PROFIsafe network.
A maximum of 4 BDF200-FB control panels can be connected.
The safety signals from the connected safety switchgear are forwarded
to a safety controller via the safety field bus for evaluation.
For larger safety applications, multiple fieldboxes can be connected to
the power supply and field bus in series.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
The non-safe IO signals of the connected devices are connected to the
control system via the field bus.
Safety switchgear with parallel IO signals can be connected to
device ports X0 - X7.
BDF200-FB control panels can only be connected to
device ports X4 - X7.

All fieldboxes have a good resistance against chemicals
and oil. When used in aggressive media (e.g. chemicals,
oils, lubricants and coolants in high concentrations) the
material resistance must in each case be checked in
advance for the specific application.
