Abstract
The utility model discloses a switching value output module which comprises a power supply, two relays, two audions and an inverter. The two relays are respectively connected with a diode in parallel and then connected to the power supply. The first relay is connected with an emitter of the first audion, and the second relay is connected with an emitter of the second audion. Bases of the two audions are both connected with the inverter. The switching value output module is simple in structure and capable of effectively controlling the state of a level, achieves complete isolation of the switching value output, ensures drive capability of the level, and saves cost.
Description
Technical field
The utility model relates to switching value output module.
Background technology
The impact to control system is very large greatly for some equipment operating electric currents in the electric power system, the amount of opening the light of isolation exports to control the break-make of such equipment fully, existing switching value output module need to come by many driving chips and latch state and the driving force of control level, cost is high, and implementation is too complicated.
Summary of the invention
Technical problem to be solved in the utility model is for the prior art deficiency, to provide a kind of switching value output module, the fully isolation of realization switching value output, the state of effective control level, the driving force of assurance level, saving cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of switching value output module, comprise power supply, two relays, two triodes, inverter, described two relays respectively with behind the diodes in parallel access power supply, first relay is connected with the emitter of first triode, second relay is connected with the emitter of second triode, and the base stage of two triodes all accesses inverter.
Compared with prior art, the beneficial effect that the utility model has is: the utility model is simple in structure, has realized the fully isolation of switching value output, and the state of control level effectively, has guaranteed the driving force of level, has saved cost.
Description of drawings
Fig. 1 is the utility model one embodiment circuit theory diagrams.
Embodiment
As shown in Figure 1, the utility model one embodiment comprises 5V DC power supply, two relay R ELAY2, RELAY1, two triode QC1, QC2, inverter 74HC14, described two relay R ELAY2, RELAY1 respectively with after diode DO2, a DO1 are in parallel access the 5V DC power supply, first relay R ELAY2 is connected with the emitter of first triode QC2, second relay R ELAY1 is connected with the emitter of second triode QC1, and the base stage of two triode QC1, QC2 all accesses inverter 74HC14.
Behind the signal process triode QC1 of two non-gate levels of 74HC14 chip, driving force strengthens, and drives at last the primary coil of relay, controls the break-make of secondary nodes, fully isolating switch amount signal output, and driving high-current switch amount signal is exported.
