Abstract
Data transmission protection circuit. Consists of the coupled arrangement of two coils 1 and a resistance 2 in parallel to the output of the coils 1, producing a wetting current, with the primary and secondary windings of the coils made simultaneously in different layers, in such a way that the magnetic flux between windings remains balanced, being situated between the User Terminal Equipment and the control device or switchboard to which it belongs and having a printed circuit board, housed in a casing that has a female connection for the input and a cable with a male termination for the output.
