Operating instructions
The digital outputs are protected against overloads (Max 500mA) and short-circuits; in case of
overload the output will switch off until the anomaly is removed.
If inductive loads, such as relays, solenoid valves, etc. have to be driven, connect a flyback diode in
parallel to the load.
