PURPOSE:To enable to start the self-scanning operation by only giving one shot input through resetting FF with the output of the self scanning circuit and to enable to return the circuit to the reset state automatically at the end of scanning operation. CONSTITUTION:When a push switch PS is turned on for a short time, an FF is set and the self scanning circuit X starts the operation and switch elements SW1, SW2... of remote control relay circuits A1, A2... are sequentially turned on for a short time. Thus, a current having the polarity determined with contacts b, c of an operation switch SW0 flows to magnetic holding type electromagnetic relays Ry1, Ry2..., and output contacts S1, S2... are sequentially switched on or off. When the switch SW0 is connected to a make contact, the output contacts S1, S2... of the remote control relays A1, A2 can be turned on or off by the operation. |
