CIB_SR inputs
4.3 Dimensions of the smartPAD holder (optional)
The diagram (>>> Fig. 4-2 ) shows the dimensions and drilling locations for
mounting on the safety fence.
Switching level of the inputs The state for the inputs is not defined for
the voltage range from 5 V to 11 V (transi-
tion range). Either the ON state or the OFF
state is set.
OFF state for the voltage range from -3 V to
5 V (OFF range).
ON state for the voltage range from 11 V to
30 V (ON range).
Load current with 24 V sup-
ply voltage
> 10 mA
Load current with 18 V sup-
ply voltage
> 6.5 mA
Max. load current < 15 mA
Cable length, terminal -
sensor
< 50 m, or < 100 m wire length (outgoing
and incoming lines)
Cable cross-section, test
output - input connection
> 0.5 mm
2
Capacitive load for the test
outputs per channel
< 200 nF
Resistive load for the test
outputs per channel
< 33 Ω
Test outputs A and B are sustained short-circuit proof.
The specified currents flow via the contact element connected to the
input. This must be rated for the maximum current of 15 mA.
