The sum of the total current of the individual device ports
X0 – X7 for outputs A1 (power supply to devices) and DO
(digital output) should not exceed 850 mA.
Protection class IP67 is only reached if all M12 connectors
and blanking plugs, as well as the viewing window are
properly fastening with screws.

Safety response times, SFB
The overall reseponse time of a safety function is made up of the
following:
• Response time of the connected safety switchgear
• Delay time of the safety fieldbox SFB-PN (WCDT_Input ≤ 20 ms)
• PROFINET/PROFIsafe transmission time
• Cycle time F runtime group F-PLC
• Response time of safety shut-off element (actuator)
In addition to the maximum response time of the SFB-PN,
the response times of the connected safety switchgear, the
transmission time from PROFINET and the response times
of additional PROFIsafe components (if applicable) must be
taken into consideration.
The maximum acceptable response times of the safety
functions are defined in the risk analysis of the machine.
The safety functions, configuration of the safety fieldbox
and correct installation must be checked by a responsible
safety specialist/safety representative.
