Remote control modules for cathodic protection equipment. It refers to modules by means of which it is possible to realise the remote control of cathodic protection equipment, incorporating the module in the equipment and by means of a signal, controlling its output, there being means to also execute manual control and carry out continuous supervision of the control signal, transmitting status signals which can be displayed locally or sent to the central remote control centre. It is constituted by signalling blocks, specifically a remote signal input block, manual start-up block, remote signal monitoring block, conditioning block, treated signal monitoring block, switching control block and supply block. It permits the localisation of a loss of flow at any point of the pipeline.
