11.1.2 PLC Outputs
Transistor outputs with current limiter
Logic Unit
PL 400 / PL 410 / PL 410 B
Min. output voltage
for "1" signal
3 V under supply voltage
Nominal operating
current per output
0.1 A
1.2 A
Permitted load: resistive load; inductive load only with quenching diode parallel to inductance.
Not more than one output may be shorted on the logic unit at any one time.
One shorted output causes no overload.
No more than half of the PLC outputs may be driven at once (usage factor 0.5).
