Abstract

PURPOSE:To prevent extension of terminal equipments and monitor the load, by adding a circuit, which changes the peculiar address by its own output signal, and a circuit, which switches the output of the terminal equipment to the load by the address after change, to the terminal equipment. CONSTITUTION:Relay driving signal (c) is given as clock (d) to counter 2 through delay circuit 1 and is counted and is applied to the address input terminal to change the address of terminal equipment Ba. When receiving a signal agreeing with the address signal which agrees with this changed address, terminal equipment Ba outputs latch signal (b) for relay driving. Signal (c) is output with a short delay after signal (b). The AND output between signal (c) and decoder output (e) is used as clock (f) to drive latch 4, and signal (b) of bus 5 is latched to control the load. After that, clock (d) is delayed by latch clock (f) by 1 to change the address, and another corresponding latches are selected successively. Thus, terminal equipments corresponding to the number of outputs of decorder 3 is substituted with only one.
