Abstract
A bus modem for building and industrial electrical systems comprises a module (100) which comprises a pair of input pins (1, 2) destined to be connected to the bus and a pair of output pins (9, 10) destined to be connected to the electrical circuit of a device to be connected to the bus. The module (100) further comprises a voltage control circuit (3) able to take voltage from said bus and to control the voltage (VASB) on a capacitor (C1) disposed at the terminals of said output pins (9, 10), and a transmission control circuit (5) able to control an electronic switch (7) which controls a current limiting circuit (8) able to limit the current on the bus, during transmission of signals from the bus to the devices connected to the bus and vice versa.
