Applies to the voltage range between -30 V and +30V.
6)
As per IEC 61 131-2
7)
In case of fault (0-V cable open circuit) the max. leakage current flows in the OSSD cable.
The downstream controller must detect this status as LOW. A safe PLC (Programmable Logic Con-
troller) must be able to identify this status.
8)
The maximum rated load inductance is higher with lower switching sequence.
