DQ mode and PWM mode with switching frequency max. 100 Hz
The following graphs apply to resistive loads and inductive loads with max. 2 A total current
of the outputs per channel. Inductive loads in PWM mode require additional wiring to an
external diode; see section Wiring (Page 19). You can find the total current of the outputs for
each channel or for each module in the technical specifications.
