The individual channels are designed potential-free, so 24V and 0 V can be connected. The
inputs are designed by way that safety switchgear units with test pulses (OSSD signals) can
be connected. The signals are not evaluated, they are only filtered. The OSSD test interval
is limited to 10 ms.
The output STO-OUT at terminal 9/10 is switched against the mass of the control.

max.
min.
The maximum short-term starting current of the input is limited to 300 mA.
2.5.1.2 STO with OSSD signals
The filter time depends on the minimum input voltage and can be specified as follows:
2.5.2

Output STO

The short-circuit proof, digital output is specified in accordance with IEC61131-2. The output
rated current is 100 mA at 24 Vdc. The output is active, if the inputs STO1 and STO2 are set.
