Safety characteristic data according to EN ISO 13849-1
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)
Important
The safety terminal is supplied with communications power via the bus coupler, an
VersaPoint controller or a designated power terminal in the station. Potential routing is
used for the communications power in the VersaPoint station. For technical data,
please refer to the data sheet for the bus coupler, VersaPoint controller or power
terminal used.
Current consumption
230 mA, maximum
Supply voltage U
M
(actuators)
Important
The safety terminal is supplied with main voltage U
M
via the bus coupler, an VersaPoint
controller or a power terminal in the station. Potential routing is used for the main
voltage in the VersaPoint station. For technical data, please refer to the data sheet for
the bus coupler, VersaPoint controller or power terminal used.
WARNING
Loss of the safety function when using unsuitable power supplies
Only use power supplies according to EN 50178/VDE 0160 (PELV).
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, ripple included.
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)
