As per IEC 61 131-2.

Applies to the voltage range between –30 V and +30 V.
7)
As per IEC 61 131-2.
8)
In the case of a fault (0 V cable open circuit) the max. leakage current flows in the OSSD cable. The down-
stream controller must detect this status as LOW. A safe PLC (Programmable Logic Controller) must be able to
identify this status.
9)
The maximum rated load inductance is higher with lower switching sequence.
10)
When active, the outputs are tested cyclically (brief LOW). When selecting the downstream controllers, make
sure that the test pulses do not result in deactivation when using the above parameters.
