A control device for powered opening of gates or the like comprises a ratiomotor (10) which operates a gate or the like by means of a kinematic motion device (11) of the known art. The ratiomotor (10) is actuated by a control logic (12) to which is connected a circuit (21) to communicate thereto the reaching by the gate of the desired ends of travel. Said circuit (21) comprises a device (22) for detecting the absolute position of the gate, a circuit (16) for management and comparison of position data taken by the device (22) with two predetermined values, two pushbuttons (18) and (19), respectively to control memorization in nonvolatile memory means (17) of said predetermined values obtained as position data for the gate in the two positions considered end positions of its travel, a luminous status indicator (20) indicating completion of memorization. The device (22) for detection of the absolute position of the gate is embodied to advantage with an analog/digital conversion circuit (15) for a signal coming from a potentiometer (14) applied to the ratiomotor (10) so as to be operated during movement of the gate. |
