Abstract: The invention relates to a data input module for inputting data, by means of electrical contact, to a monitoring/control module, the module including a first voltage feed input (1) and a second voltage feed input (2), which inputs are intended to be subjected to a potential difference which is optionally variable, and a plurality of contacts (3) each of which has a first terminal (4) connected to the first input via a first resistor (14), and a second terminal (5) connected to the second input (2), each contact being designed to open or to close an electric current path between its terminals. The module further includes detection members (7) respectively associated with the contacts. Each detection member is organized to detect the presence or the absence of current flowing between the terminals of the contact with which the detection member is associated.
