Description
Technical field
The present invention relates to Control technical field, particularly relate to a kind of control relay circuit.
Background technology
Relay is a kind of electronic control device, and it is the one " automatic switch " going to control larger current with less electric current.Therefore play the effects such as automatic adjustment, safeguard protection, change-over circuit in circuit.
The control mode majority of current relay adopts the nominal pick-up voltage of relay directly to supply relay.The shortcoming of this scheme is that relay works at high load conditions always, and cause relay oneself power consumption large, caloric value is large, so that reduces the useful life of relay.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of control relay circuit, can reduce the power consumption of relay.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of control relay circuit, comprise photoelectrical coupler, first resistance, second resistance, 3rd resistance, triode, electric capacity, voltage stabilizing didoe, relay coil, diode, light-emitting diode and the 4th resistance, one end of first resistance described in an input termination of described photoelectrical coupler, another termination control signal of described first resistance, another input end grounding of described photoelectrical coupler, one of described photoelectrical coupler exports termination bias voltage, another output of described photoelectrical coupler connects the base stage of described triode by the second resistance, the grounded emitter of described triode, between the base stage that described 3rd resistance is connected on described triode and emitter, the collector electrode of described triode is connected with one end of described electric capacity with the anode of described voltage stabilizing didoe, the negative electrode of described voltage stabilizing didoe is connected with one end of described relay coil and the anode of described diode with the other end of described electric capacity, the other end of described relay coil and the negative electrode of described diode connect supply voltage, the negative electrode of described light-emitting diode connects the anode of described diode by described 4th resistance, the anode of described light-emitting diode connects the negative electrode of described diode.

Be different from the situation of prior art, the invention has the beneficial effects as follows: control signal isolation is amplified by photoelectrical coupler, control signal can be made more stable, and be connected between triode and relay coil after voltage stabilizing didoe and Capacitance parallel connection, under being operated in ME for maintenance after can making relay adhesive, thus reach the object of the power consumption reducing relay.
Accompanying drawing explanation
Fig. 1 is the circuit theory schematic diagram of embodiment of the present invention control relay circuit.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the circuit theory schematic diagram of embodiment of the present invention control relay circuit.The control relay circuit of the present embodiment comprises photoelectrical coupler U, the first resistance R1, the second resistance R2, the 3rd resistance R3, triode Q, electric capacity C, voltage stabilizing didoe VD, relay coil J, diode D1, light-emitting diode D2 and the 4th resistance R4.
Wherein, photoelectrical coupler U has two inputs and two outputs, one end of an input termination first resistance R1, another termination control signal of first resistance R1, another input end grounding, one exports termination bias voltage Vb, and another output connects the base stage of triode Q by the second resistance R2.
The grounded emitter of triode Q, between the base stage that 3rd resistance R3 is connected on triode Q and emitter, the collector electrode of triode Q is connected with one end of electric capacity C with the anode of voltage stabilizing didoe VD, the negative electrode of voltage stabilizing didoe VD is connected with one end of relay coil J and the anode of diode D1 with the other end of electric capacity C, the other end of relay coil J and the negative electrode of diode D1 meet supply voltage VDD, the negative electrode of light-emitting diode D2 connects the anode of diode D1 by the 4th resistance R4, the anode of light-emitting diode D2 connects the negative electrode of diode D1.In the present embodiment, supply voltage VDD is 24V, and bias voltage Vb is 5V.
During control relay circuit work, control signal isolates amplification through photoelectrical coupler U, the output of photoelectrical coupler U provides base current for triode Q, the rapid conducting of triode Q, because the voltage at electric capacity C two ends can not suddenly change, be added on relay coil J so be equivalent to supply voltage VDD, the normally opened contact of relay is closed, normally-closed contact disconnects to make relay have enough large the suction-combining force to make.Along with electric capacity C both end voltage be elevated to the voltage of voltage regulation of voltage stabilizing didoe VD gradually time, the voltage that voltage stabilizing didoe VD starts working and relay coil J two ends are born is the voltage of voltage regulation that supply voltage VDD deducts voltage stabilizing didoe VD. thus under being operated in ME for maintenance after making relay adhesive, to reach the object of the power consumption reducing relay, thus can reduce caloric value and increase the service life.
In addition, because relay major part is mounted in the inside of machine, its operating state is not directly perceived, by circuit of by four resistance R4 and light-emitting diode D2 being connected in parallel at the two ends of relay coil J, when relay coil J is energized, light-emitting diode D2 is bright, thus can understand the operating state of relay intuitively.
By the way, control signal isolation is amplified by photoelectrical coupler by the control relay circuit of the embodiment of the present invention, control signal can be made more stable, and be connected between triode and relay coil after voltage stabilizing didoe and Capacitance parallel connection, under being operated in ME for maintenance after can making relay adhesive, thus reach the object of the power consumption reducing relay.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
