A control and monitoring signal transmission system according to the present invention includes a master station that transmits and receives data to and from a control unit, and a plurality of remote stations that transmit and receive data to and from the master station by a transmission synchronization method via a common transmission line. Then, in the period between the clock voltage ranges of the voltage clock signal having a predetermined period and duty ratio, when the impedance of the circuit at the first state of the first voltage level set to the target after changing the voltage level becomes higher than the impedance at the start state before changing the voltage level, which circuit composed of a plurality of internal circuits of the remote stations and the transmission line, the impedance is changed to the first voltage level via a second voltage level that takes a second state wherein the impedance is lower than the impedance at the first state.
