<p>The object of this invention is an interface device (1) for control apparatuses formed by sensors (44) of the antitheft type, applied, for instance, in different places which are to be watched as doors, windows and the like, or of another type such as anti-fire, anti-flooding and the like, and one or more computers (10A) (10B) which receive the information from said sensors, elaborate said information according to predetermined programs loaded into said computers, and then send to the interface (1) the necessary instructions for activating the actuators (45) of the physical operations of the control. Said device (1) includes an intelligent unit formed by a central processing unit (2) having permanent and volatile memories (3) and parallel/serial conversion circuits (8) for serial communication with the computer (10A) and with possible accessory management devices (9), parallel input/output circuits (4) (5) (6) (7), in combination with an interface unit in which the number of the contacts for the control functions and the number of the digital optoisolated inputs for the logic states of the sensors may be selected according to the special purposes required.</p> |
