Figure 750: Switching inductive loads
In principle, the inductance that is connected is limited by the maximum power dissipation of the module.
If larger inductances or more current are used, the the "transil-diode combination" must be placed externally on
the relay/valve (see 4.26.4.6 "Connection example").
Information:
The inductance of a relay/valve depends greatly on the core material being used. Therefore, an induc-
tance must be used that corresponds to the diagram at 1Hz. This information can be found in the data
sheet of the connected inductance (relay/valve).
