ProtectionEach output is overcurrent, overtemperature, load dump and reverse polarity protected.
Soft StartPWM soft start can be enabled on outputs to limit inrush current.
PWMEach output can be Pulse Width Modulated based on a user defined variable. This can limit the speed of radiator fans, fuel pumps, and dim lights.

1000Hz maximum PWM frequency

Added FeaturesOutputs can be configured to stay on for a specified time after the input is removed, useful for thermo-fans.
Outputs can be retried multiple times after an over-current event is detected.
