Switching Outputs 24 Vdc For The Plc - HEIDENHAIN TNC 370 D Technical Information

3.7.8 Switching Outputs 24 Vdc for the PLC

Transistor outputs with current limiting
Min. output voltage for "1" signal
Nominal operating current per output
·
Permissible load: resistive load; inductive load only with quenching diode parallel to the
inductance.
·
No more than one output may be shorted on the logic unit at any time. Short circuit of one
output does not cause an overload.
·
No more than half the PLC outputs may be driven at the same time (simultaneity factor 0.5).
