Electronic industrial control device, characterized in that it consists of an amplifier integrating circuit of the currents generated by multiple photoelectric signals in photosensitive elements such as photodiodes, phototransmitters and cadmium sulfide cells, for which a voltage input is provided to which it divides in two parts a resistance, adjusting these two branches in such a way that, one of them, has photosensitive elements that, when they are illuminated, cause the zener point in a zener diode becoming this conductive branch and sending impulsion over a transistor amplifier capable of producing, in these conditions, a current capable of operating the electromagnetic mechanism intended to control the machine to which it is applied, the other branch operating analogously, but achieving an opposite effect, that is, of cancellation of operation by current opposition.
