The telephone control is used to connect/disconnect electrical devices with a 230V/50 Hz power supply. It allows connecting and disconnecting the plugged-in device manually or by telephone. If the connection is made through a telephone call, it is necessary to dial the assigned access code. The telephone control is powered at 230V/50Hz by means of the socket that it incorporates. The Telephone Control can be connected to the telephone line as a single installation or in the framework of a configuration with other installations connected later that are allowed.
