Technical specifications
PWM mode with switching frequency max. 500 Hz
The following graphs apply to resistive loads and inductive loads with max. 2 A total current
of the outputs per channel. Inductive loads require additional wiring with 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.
