Response times
Maximum response time of outputs:
The maximum response time of the EM 4 F-DI/3 F-DO DC24V PROFIsafe (with or without
fault) is equivalent to the maximum internal processing time T
The internal processing times of the electronic PM channel depend on the readback time
parameter setting (see table below).

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 (with or without fault)
is equivalent to the maximum internal processing time T
The internal processing times of the electronic PM channel depend on the readback time
parameter setting (see table below).

Maximum response time of the EM 1 F-RO DC24V/AC24..230V/5A
The maximum response time of the EM 1 F-RO DC24V/AC24..230V/5A (with or without
fault) is equivalent to the total of:
● the maximum response time of the fail-safe output used to activate the F-RO module
● plus the relay switching or release time of the F-RO module
