Description of drawings
Fig. 1 is that the utility model circuit connects synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1; The utility model provides a kind of output circuit of dry-type transformer temperature controller; Comprise the MCU of dry-type transformer temperature controller, it is characterized in that, also comprise: a transistor 9014; This transistorized base stage is connected this transistorized grounded emitter through a resistance R 13 with the output terminal of said single-chip microcomputer; One capacitor C 34, an end of this electric capacity is connected with said transistorized base stage, the other end ground connection of this electric capacity; One relay J 6, coil one end of this relay is connected with said transistorized collector, another termination power of coil; And a protection diode D12, the positive pole of this protection diode is connected with said transistorized collector, and negative pole connects said power supply.
In the present embodiment, described MCU is a single-chip microcomputer, and described transistor is 9014 transistors; Please continue with reference to Fig. 1, we send the break-make of instruction through the transistor controls relay through MCU among Fig. 1, in practical application; Because the Be Controlled of dry-type transformer temperature controller partly is that its inside display parameter with temperature controller of fixing are consistent; For example current procuratorial work is to temperature exceeding standard, and then device is controlled temperature controlled output port, if this equipment did not originally have temperature controlled output port; The output circuit of this present embodiment of keyboard to set up that at this moment user just can be through system is a temperature control output end mouth; Like this, set the back user, just can realize control as long as port S10 and S11 are received control corresponding equipment.Can effectively avoid not going to producer customized because there being the corresponding port.Realized the flexible Application of port.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
