With a connected RC quenching element (jumper “SJ”
inserted) or with an external protection circuit, you
lengthen the service life of the contacts.

Connecting two outputs in parallel
• For redundant triggering of
a load
Possible (only outputs
with identical load vol-
tage)
• To increase performance Not possible
Triggering a digital input Possible
Switch rate
• Mechanical max. 10 Hz
• For resistive load max. 2 Hz
• Inductive loads according
to IEC 947-5-1, DC 13/15
AC
max. 0.5 Hz
• For lamp load max. 2 Hz
1)
Without inserted jumper (SJ).
2)
For AC load voltage and inserted jumper (SJ).
Without jumper (SJ) inserted there is a leakage
current
Note
Due to the leakage current of the RC quenching element, wrong signal states
might occur when an IEC Type 1 input is connected (remove SJ jumper)
