How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps.
Design PLC peripheral hardware circuit.
Including the main circuit and the control circuit does not enter the PLC, etc..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined.
Input voltage range: AC100-120V/AC200-240V.
Output voltage: DC5V.
Output current: 8A.
For Q4ARCPU.
The control module monitors the power supply, the error
CPU state,
And its own error state.
It sends out
Error signal a6raf and open the corresponding
Relay output.
I/O points is an important indicator of PLC MITSUBISHI AJ71QLP21G.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest
AJ71QLP21G
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30% MITSUBISHI AJ71QLP21G.
The following describes the centralized control system I/O points of the estimate. Output points: 16 points.
Voltage: DC24V/AC240V, 2A/1 point, 16A/ all points.
OFF leakage current: 0.1mA.
Output type: relay output.
Response time: 12ms.
All points of independence.
38 point terminal station MITSUBISHI AJ71QLP21G.
With the surge absorber.
CE certification.
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 MITSUBISHI GI fiber optic cable module MITSUBISHI GI fiber optic cable module.
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 MITSUBISHI GI fiber optic cable module.
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.
Control solenoid valve required I/O points by the action principle of the solenoid valve can 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 MITSUBISHI AJ71QLP21G AJ71QLP21G.
