In automation systems, the protection of individual circuits from short circuits is important. This is usually done with the help of automatic switches or fuses. The automation does not always work as expected, because the power supply does not provide sufficient current to shut off the machine so that everything that stays behind the power supply fails to work properly. In both cases, even when the protection is triggered, it is necessary to correct the fault and to re-activate the protection. The listed problems do not have electronic security, which can have up to 8 channels, each of which can be very precisely defined when it is summer. This way the system operates smoothly, disconnects only separate circuits where the fault occurs, many electronic protectors can remotely transmit fault information, and can either enable or disable any channel remotely. The protection is made at a voltage of 12 to 48VDC and can operate at up to 10A. There is also an RS232 interface.
