Programmable logic controller PLC and correlation module thereof are installed in casing by the utility model on the one hand, and be welded on pcb board, integrated level is high, substantially reduce the volume of PLC comprehensive practical traning equipment, reduce cost, be easy to carry, arbitrarily can move to different place exercise Programmable Logic Controllers, practicality and dirigibility strengthen greatly; The utility model is based on systematic teaching development and Design on the other hand, has the functions such as logic control, sequential control, Analog control, step motion control.PLC experimental box comprises the input signal of common sensor (proximity switch, PT100) as PLC, and export control object (direct current generator), formed from the input of signal, to PLC again to the complete mini system of controlled device, allow student go in systems in which study and receive knowledge.Student, through the training of this experimental box, will contribute to the deeply thorough understanding in knowledge point and grasp, and can go the ability of analysis and solve problem from system perspective by subtle training student, meanwhile, experimental box can simulate kinds of experiments, comprehensive stronger.
As improvement of the present utility model, also comprise current limliting module, current limliting module is connected with the output terminal of controller PLC.
Current limliting module can the output port of available protecting controller, prevents output port short circuit from burning out.
As further improvement of the utility model, the input end of described controller PLC and output terminal all adopt the quick plug of plug type.
The input and output signal that controller outside is convenient in the rapid-acting coupling of plug-in is connected fast with controller PLC, has dirigibility, can allow learner's wiring freely, cultivates learner's practical competence, makes learner fundamentally grasp controller PLC.
Further improve as of the present utility model, the given module of described switching value is button or switch.
By disconnecting or closing switch, to press or sprung push buttons sends signal to controller PLC.
In sum, the beneficial effects of the utility model are: experimental box volume is little, be easy to carry, multiple functional, cheap.
Accompanying drawing explanation
Figure 1 shows that the graph of a relation of I/O of the present utility model and functional module and PLC.
Figure 2 shows that PLC experimental box panel designs figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, the utility model provides a kind of portable integrated PLC experimental box, experimental box can analog acquisition on-off model, analog signals, to the control of motor, color lamp, hummer, simulation stirrer, traffic lights, functions such as comprising logic control, sequential control, Analog control, step motor control can be had.
As shown in Figure 2, experimental box is stirred module 17, relay module 18, traffic signals lamp module 19, NPN type proximity switch 20 and direct current generator 21 formed by programmable controller PLC (FX3G-24MT) 1, analog module 2, On-off signal port 3, analog input port 4, output switch parameter port 5, analog output port 6, experimental box power switch 7,24V DC source 8, charactron 9, hummer 10, electricity Ya electric current indicator gauge 11, color indication lights 12, switch 13, stepper motor module 14, button 15, temperature sensor 16, liquid level.
