Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC MITSUBISHI A0J2-C10B A0J2-C10B
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light.
When the switch is off, the diode does not emit light, and the transistor is not on the way MITSUBISHI A0J2-C10B. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process MITSUBISHI A0J2-C10B.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive. Input points: 16 points.

The number of I/O thyristor DC motor control required tube DC motor speed control system is the main form of DC speed regulation,
The thyristor rectifier unit is used to supply power to the DC motor.
PLC control of the DC drive system, the input of the PLC in addition to the main signal outside the signal,
We need to consider the switching signal, the fault signal transmission device, brake signal and fan fault signal.
The output of the PLC mainly consider the speed command signal positive 1~3 level, 1~3 level, allowing reverse switching signal and brake open signal etc..
In general, a reversible DC drive system controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points.

Control solenoid valve required I/O points by the action principle of the solenoid valve caan be known,
A single coil solenoid valve with PLC control to 2 input and 1 output,
A double coil solenoid valve requires 3 inputs and 2 outputs,
A button needs an input; a light sensitive switch needs 4 or 2 inputs,
A signal lamp needs 1 output, band switch,
Several bands are required for several inputs,
In general, a variety of position switches are required to take up 2 input points A0J2-C10B A0J2-C10B.
