Signals at the output
"0" signal (0 V) at the output:

– Output is high impedance
– No current to the load
– Safety function not activated
"1" signal (+24 V) at the output:

– Output is low impedance
– Current is supplied to the load
– Safety function activated
Supply voltage
24 VDC connection to supply the safety card's digital outputs

The safety card has a dual-pole output to control an external mechanical
brake:

SBC+/SBC-
Signals at the output
"0" signal (0 V) at the output (SBC+/SBC-):

– Output is high impedance
– No current to the load
– Safety function is activated, brake closed
"1" signal (+24 V) at the output (SBC+/SBC-):

– Output is low impedance
– Current is supplied to the load
– Safety function is not activated, brake open
NOTICE
Only a brake which operates in accordance with the failsafe
principle may be connected.
