Abstract
The open a kind of temperature control experiments device of this utility model, belong to technical field of electric control, mainly for being difficult to control under prior art, power is bigger, cause overload to cause dangerous problem, propose a kind of temperature control experiments device, including heated seats, heated seats is vertically installed with heating rod and temperature sensor；Temperature sensor top is connected to temperature transmitter；Temperature transmitter right part is connected to direct-current switch power supply, and top is connected to analogue collection module；The analogue collection module left side is connected to PLC；The PLC left side connects wife's solid-state relay；Solid-state relay bottom is connected to heating rod, and the left side is connected to alternating current power supply.This utility model can accurately control output, temperature controlled experiment purpose, ensures safety.
Description
Technical field
This utility model relates to a kind of temperature control experiments device, belongs to technical field of electric control.
Background technology
In PLC Analog control is tested, it is modal experiment that temperature controls, the control object of present experimental provision
Being typically to heat water with heating rod, this method generally selects more powerful heating rod to reach reasonable experiment effect
Really, when many group experiments are carried out simultaneously, because power is bigger, one is that power consumption causes greatly waste, and two is that current ratio is easily made relatively greatly
Overload is become to cause danger.In order to cost-effective, ensuring safety, therefore a kind of low-power temperature control experiments device of design is very
Necessary.
Utility model content
For solving the problems referred to above, the purpose of this utility model is precisely in order to solve above-mentioned the deficiencies in the prior art, this practicality
Novel purpose is to provide a kind of temperature control experiments device.
For solving the problems referred to above, this utility model is achieved through the following technical solutions: a kind of temperature control experiments dress
Put be by heating rod 1, heated seats 2, temperature sensor 3, temperature transmitter 4, direct-current switch power supply 5, analogue collection module 6,
PLC 7, solid-state relay 8 and alternating current power supply 9 form；It is characterized in that: be vertically installed with in described heated seats 1 and add
Hot pin 1 and temperature sensor 2；Described temperature sensor top is connected to temperature transmitter；Described temperature transmitter right part
Being connected to direct-current switch power supply, top is connected to analogue collection module；The described analogue collection module left side is connected to PLC
Controller；The described PLC left side connects wife's solid-state relay；Described solid-state relay bottom is connected to heating rod,
The left side is connected to alternating current power supply.
The beneficial effects of the utility model are: a kind of temperature control experiments device, simple in construction, power are little, easy-to-connect,
The advantages such as safe and reliable, easy operation.
Accompanying drawing explanation
Fig. 1 is a kind of temperature control experiments apparatus structure schematic diagram.
Detailed description of the invention
As it is shown in figure 1, a kind of temperature control experiments device is to be become by heating rod 1, heated seats 2, temperature sensor 3, temperature
Device 4, direct-current switch power supply 5, analogue collection module 6, PLC 7, solid-state relay 8 and alternating current power supply 9 is sent to form；Its
It is characterised by: described alternating current power supply 9 is powered to heating rod 1, and direct-current switch power supply 5 powers to temperature transmitter 4, heating rod 1
Heated seats 2 is heated by the heating rod using smaller power, temperature sensor 3 detects the temperature of heated seats 2 in real time, temperature becomes
Sending input analog amount acquisition module 6 after the signal conversion that temperature sensor 3 detects by device 4, PLC 7 is adopted according to analog quantity
The feedback of collection module 6 controls the output of solid-state relay 8, thus reaches temperature controlled experiment purpose.
Below disclose this utility model with preferable enforcement, so itself and be not used to limit this utility model, all take
With the technical scheme replaced or equivalent transformation is obtained, all fall within protection domain of the present utility model.
