The invention relates to automation can be used in relay devices for various purposes.

The aim of the invention is to simplify the decoder.

The drawing shows a functional decoder circuit.

The decoder contains windings 1-3 of the main electromagnetic relays, Q green 4 decryption stages, consisting of groups 1, - 2, 3, - 3 contacts of the corresponding relays, the first 5 and second 6 elements of the load, the winding 7 of the additional electromagnetic relay, group 7, contacts of an additional electromagnetic relay, heating element 8, elements of 9 times. In the drawing, the power supply bus 10, the inputs P, and the outlets-12 of the decoder 12 are indicated.

The decoder works as follows.

When acting on the inputs 11 of the decoder of the code combination, 25 electromagnetic relays 1-3 are activated and their contacts 1, - 2j, 3, - 3 are set to the appropriate position and the circuits are prepared for the output signals of the decoder.

At the same time, the signals from the inputs 11 are fed through the elements of 9 isolations (diodes) and the first load element 5 (resistor) to the winding 7 of the additional electromagnetic relay.

After the time C required for charging accumulative element 8 (capacitor) to the tripping voltage of the circuit: inputs 11, diodes 9, load elements 5, disconnecting contact of group 7, movable 0 contact of the same group 7, bus 10, the auxiliary relay 7 triggers and the short-circuiting contact of group 7 is closed and forms a circuit to output the output of the decoder. At the same time, the charge circuit of storage element 8, which is now discharged to load element 6, is disconnected, preparing the circuit for receiving the next code pattern. 50

When removing signals from the code combination from inputs 11, the additional electromagnetic relay 7 releases its contacts 7, earlier than the electromagnetic relays 1-3, since the saturation is 55

its core magnetic flux is significantly less than that of electromagnetic relays 1-3 due to the inclusion of load element 5 in series with the winding 7 of an additional electromagnetic relay.

Thus, the outputs 12 are received after the end of the transients of the decoding node 4, and when the code combination is removed from the inputs 11, the output signals are removed before the beginning of the transients in the decoding node 4, thus eliminating spurious signals at the output during switching of the node 4 decryption and that provides the possibility of building a decoder for an unlimited number of outputs.
