Electronic circuit associated with at least one pneumatic circuit, comprised by an interphase block related to a compressor low pressure sensor connecting with the pneumatic circuit by means of check valves and additional sensors per tire to be controlled, for example, the shafts of a system the wheels of which are connected by means of electrovalves. The interphase block is connected with corresponding power outlet blocks represented by the electrovalves. The regulated supply source block, the low pressure sensor block and load blocks are connected to an indication block. In this way, pneumatic circuits are continuously checked and the proper pressure is assured at any time, further the automatic compensation of any air loss is obtained.
