Abstract:
The invention concerns a control and monitoring device for a switch machine of a railway switch comprising: a power supply for providing a switch motor of the switch machine with a current, the switch motor being adapted to move points of the railway switch, a relay having a primary contact connected electrically to the power supply via at least one line and a secondary contact adapted to be electrically connected to the switch motor; the relay being adapted to switch on and off the power provided to the switch motor; at least one current sensor adapted to sense the current to be provided to the switch motor at the at least one line between the power supply and the relay; at least one voltage sensor adapted to sense a voltage to be provided to the switch motor at the at least one line between the power supply and the relay; a monitoring module connected to the at least one current sensor and the at least one voltage sensor, wherein the monitoring module is adapted to record the measured current and voltage values.
