DEVICE FOR ELECTRIC DETONATOR IGNITION

The device is used for electric detonator ignition. It comprises an inverter with an enable input connected to the output of a comparator, and its output is coupled to a voltage divider, capacitor and terminal, and across a resistor by means of a second terminal. The terminals are zero connected across electronic switches controlled by a controller. The inputs of the comparator are connected across a filter to the divider, and to a reference source, respectively. A storage battery supplies the inverter across a third electronic switch, controlled by the controller, controlling two more light emitting diodes (LEDs) and a fourth switch connected in parallel to two jacks, as well as analogue-digital inverter having reference source and two channels, connected to the filter, respectively, and across current switch - to the storage battery, together with the reference source and an information input of the controller, having in addition a logic output coupled to the comparator. The jacks, across plugs, a Graetz rectifier and a diode, supply an electrolytic capacitor and a logic controller having an information input and controlling two LEDs and a fifth electronic switch connected in parallel to the rectifier. 1 claim, 1 figure
