PURPOSE:To obtain a transmitter for integrated signals capable of being reliably operated even in power failures by detecting the switching output of an electrisity integrating circuit which makes switching of two electrochemical time limitting elements alternately with opposite polarities. CONSTITUTION:Voltages between anodes and cathodes of electrochemical time limitting elements 17-1, 17-2 are detected by diodes 26-1, 26-2, respectively, and switching terminals a, b for controlling ON and OFF of transistors 18-1, 18-2 to switch input terminals of a power supply source 19 are switched over by a latching relay 27. When the switching terminals is turned to the side a, cathode ions are attached on the anode in a predetermined amount at the time limitting element 17-2, while at the time limitting element 17-1 cathode ions attached on the anode return to the cathode in response to an input signal from an input teminal 30. As the cathode ions are completely returned, the diode 26-1 issues output. The latching relay 27 is operated by thus issued output to switch the terminals a b. When the time limitting elements 17-1, 17-2 are subjected to opposite operation to the above, pulses corresponding to the integrated value of the input signal are obtained by the outputs from the diodes 26-1, 26-2. |
