PURPOSE:To reduce the power consumption without polarized relays corresponding to the number of slave stations, by connecting a plurality of slave station transmission lines in parallel to a single polarized relay and forming 1:n opposing system. CONSTITUTION:Transmission lines l1-ln connected to slave station side transmission section are provided with signal current adjusting resistors R11-Rn1 and slave station switching contacts K12-Kn2 sequentially making. The transmission lines are connected in parallel with the polarized relay K to activate the relay K with a signal current flowing when either one of the contacts make. The relay contact k of the polarized relay K is provided in an output line DC of a reception transmitting line and the signal of the slave station is outputted to the output line DC through the operation of the relay K. Without providing the polarized relays K corresponding to the number of slave stations, 1:n opposing remote monitor control system is constituted to reduce the power consumption. |
