Abstract

The utility model relates to a logic circuit, especially to a logic circuit realized by relays. The logic circuit comprises two or more than two signal logic control circuits, wherein each signal logic control circuit comprises one power off relay and a signal input source, the power off relays are connected with a power supply relay, and the power supply relay includes a signal output source. The logic control circuit employs the multiple relays for control, and signals can be output only if the signals are sequentially emitted. The two signal logic control circuits are realized by the three relays, which can be expanded into that X-1 signal logic control circuits are realized by X relays. According to the utility model, logic control is realized by the multiple relays, the circuit is simple, realization is convenient, and the logic circuit is characterized by the capabilities of directly controlling large voltage and large current.

Description

The logical circuit that a kind of relay is realized
Technical field
The utility model relates to a kind of logical circuit, relates in particular to the logical circuit that a kind of relay is realized.
Background technology
That relay is widely used in is military, in consumer electronic device control circuit, for isolation control signal and load.When some special output requires to only have control signal to send by predetermined logical order, could export.At present, logic control circuit generally adopts chip digital circuit, and circuit is more complicated, higher to designer's technical requirement.
Summary of the invention
The utility model is in order to overcome above-mentioned defect, and object is to provide a kind of circuit simple, and it is convenient to realize, and has the logical circuit of the relay realization that can directly control large voltage, large electric current.
To achieve these goals, the utility model adopts following technical scheme:
The logical circuit that relay is realized, it comprises 2 tunnels or signal logic control circuit ，Mei road signal logic control circuits more than 2 tunnels, and it comprises a cut-off relay and signal input sources; All cut-off relays are connected with supply relay, and supply relay has signal output source.
The beneficial effects of the utility model:
The utility model adopts many Controls, realizes signal and must send in order the function that circuit could be exported.3 relays are realized 2 road signal logics and are controlled, and can realize expanded function, and X relay can be realized X-1 road signal logic and control.
The utility model adopts many relays to realize logic control, and circuit is simple, and it is convenient to realize, and has the advantages that directly to control large voltage, large electric current.
Accompanying drawing explanation
Fig. 1 is the structural representation that in the utility model, 2 road signal logics are controlled.
Fig. 2 is the structural representation that in the utility model, 4 road signal logics are controlled.
Embodiment
Below in conjunction with 1,2 pairs of the utility model of accompanying drawing, be elaborated:
The logical circuit that relay is realized, it comprise 2 tunnels or 4 tunnels signal logic control circuit ，Mei road signal logic control circuit it comprise a cut-off relay 1 and signal input sources 2; All cut-off relays 1 are connected with supply relay 3, and supply relay 3 has signal output source 4.
Other multi-channel logic control circuit can be analogized, and every increase by one road signal just increases a relay.
During circuit normal operation, signal input sources 2 ... send in order, first via signal sends rear disconnection No. second cut-off relay, the second road signal sends rear disconnection Third Road cut-off relay, X road signal sends rear disconnection X+1 road cut-off relay, it is closed that last road signal sends rear supply relay, circuit output.When signal logic is made mistakes, when the signal above of signal ratio below first sends, cut-off relay will be action, disconnect output circuit, and circuit can not be exported, and realize the logic control function of circuit.
