Maximum Response Time of the EM 4 F-DO DC24V/2A PROFIsafe
The maximum response time of the EM 4 F-DO DC24V/2A PROFIsafe (without a fault and
when a fault exists) corresponds to the maximum internal conditioning time T
The internal conditioning times of the electronic PM channel depend on the readback time
parameter setting (see table below).
