We found this circuit in a 1997 documentation. It can be used in any common 12 V source and has two relays that disconnect the source in the event of a short circuit.
This basic voltage comparator circuit has a reference voltage given by a zener diode. The input...
With this circuit we can activate a relay with a simple touch on the sensor. The relay can be 6 or...
This circuit uses a thermistor or NTC as a temperature sensor and provides the indication on an...
