)
Depends on the parameterization (see Fig. 7-4 on page 43 )
Hardware fault tolerance (HFT) of the module 1
Permissible duration of use 20 years
Safety characteristic data according to EN 62061
Safety characteristic data according to EN ISO 13849-1
Achievable performance level PL d (single-channel)
PL e (two-channel)
Depends on the parameterization and wiring (see Chapter
“Connection Options for Actuators Depending on the Param-
eterization” on page 20 and Chapter “Connection Examples
for Safe Outputs” on page 41 )
Diagnostic coverage (DC)
99%
Mean time to dangerous failure (MTTFd) For single-channel assignment: 100 years
For two-channel assignment: 100 years
Supply voltage U
L
(logic)
The safety terminal is supplied with communications power via the bus coupler or a designated power terminal
in the station. The communications power is led in the Inline station via potential routing. For the technical data,
please refer to the data sheet for the bus coupler or power terminal used.
Current consumption 230 mA, maximum
Supply voltage U
M
(actuators)
The safety terminal is supplied with main voltage UM via the bus coupler or a power terminal in the station. The
main voltage is led in the Inline station via potential routing. For the technical data, please refer to the data sheet
for the bus coupler or power terminal used.
Nominal voltage 24 V DC according to EN 61131-2 and EN 60204
Tolerance -15%/+20% including an entire AC voltage component with
peak value of 5%
Ripple 3.6 V
pp
Permissible voltage range 19.2 V DC to 30.0 V DC, including all tolerances, ripple in-
cluded
Current consumption 30 mA, typical (all outputs set) (plus actuator current)
Permissible interruption time 10 ms;
Within this time, the output voltage for the safe outputs fails as
the outputs are not internally buffered.
Surge protection Yes (in the bus coupler/power terminal)
Protection against polarity reversal Yes (in the bus coupler/power terminal)
Loss of the safety function when using unsuitable power supplies
Only use power supplies according to EN 50178/VDE 0160 (PELV).
WARNING
Module damage due to polarity reversal
Polarity reversal places a burden on the electronics and, despite protection against polarity reversal, can damage the mod-
ule. Therefore, polarity reversal must be prevented.
