FIELD: electricity.SUBSTANCE: device has N interfacing devices which are galvanically separated from their inputs, the positive pole of power supply of the device is connected to the positive supply input, and the negative pole to the negative power input of the first separating interface device. The outputs of 1, 2, 3 ? and (N-1)interfacing devices are connected to the negative power inputs of respectively the second, the third, ? Ninterfacing devices, and the negative power inputs of N interfacing devices, starting from the first and ending with (N-1), are connected to the positive power inputs of respectively the second, the third ? Ninterfacing devices, and the output of Ninterfacing device is connected to the first lead of the polarising winding of the polarised relay the second lead of which is connected to the negative power input of N-th interfacing device. In the offered technical solution the logical function "AND" with any quantity of N inputs is implemented and one polarised relay is used.EFFECT: building of safe element implementing the logical function "AND" with any N number of inputs and using one polarised relay of the first reliability class.1 dwg |
