PURPOSE:To extremely simplify the wiring work, by programmably control a relay circuit including a latching relay. CONSTITUTION:In a processor 1, the start signal is applied to an oscillator OSC. The signal supplied from the OSC is counted by a counter CNT, and this count output is supplied to a memory M. The memory M leads out the logical signal in parallel to output terminals D0-D3 and in accordance with the output given from the CNT. For a buffer 2, relay means R0-R3 are provided to the terminals D0-D3. Then the switching modes of changeover relay switches R01-R03 are switched individually and in correspondence to each other by supplying the signals to the means R0-R3. The individual contact of each of the switches R01-R31 is connected in common to a high-level line lV and an earth-level line lG of a power supply; and the common contact is connected to lines l0-l3. These lines l0-l3 are supplied to data decoders A1 and A2; and decoders A1 and A3 apply the set and reset signals to relay circuits K1 and K2. |
