PROBLEM TO BE SOLVED: To provide an elevator signal transmission system capable of greatly reducing workload and work time of an operator in conversion work of a common line, and to provide a common line conversion method.SOLUTION: An elevator signal transmission system executes transmission and reception of a signal between a control device connected to a + side power supply line, and an indicator of each floor connected to a - side power supply line or a load including the indicator inside an elevator car. A control board for common conversion for converting - common to a + common is provided between the + side power supply line and the load. The control board includes: a suction type switching element connected to the + side power supply line, and for conducting electricity according to control command from the control device; and a semiconductor relay provided between the + side power supply line and the load, and for electrically connecting the + side power supply line and the load by the electric conduction of the switching element.SELECTED DRAWING: Figure 1
