PROBLEM TO BE SOLVED: To provide a system for transmission of signals between modules for surely transmitting information related with the start of safety equipment between modules. SOLUTION: A transmission side module for transmitting a pulse signal in a prescribed cycle showing the existence of information is configured to generate a pulse signal by time division by a plurality of signal generation parts arranged in parallel, and to summarize those pulse signals into one time-series pulse signal, and to output the pulse signal through a relay for output control to the reception side module, and to determine the presence/absence of abnormality by monitoring the signal appearing in the constant open terminal and constant close terminal of the relay, and to stop the generation of the pulse signal when abnormality is detected.
