FIELD: analog computer engineering and automatic control equipment. SUBSTANCE: device has first and second two-channel relays, each of which has differential comparator and two switching channels, which have closing and opening keys with control inputs, which are connected to output of comparator. Inputs of keys provides switching inputs of relay. Joined outputs of keys in each switching channel provide outputs of relay. Direct and inverting inputs of comparator provide comparator inputs of relay. First and second channels of second relay are connected respectively to first and second comparator inputs of first relay. Input terminals of closing and opening keys of first switching channel in second relay are connected respectively to input terminals of closing and opening keys of second switching channel. Comparator inputs and outputs of closing and opening keys of first switching channel provide respectively comparator and control inputs, while switching inputs and output of first relay serves as switching inputs and outputs of conjunction-disjunction relay. EFFECT: increased functional capabilities due to possibility to use control signal as additional information signal. 4 dwg
