MITSUBISHI A73CPUR21-S1 Product information and technical parameters:
Brand: MITSUBISHI
Name: Moving CPU unit
Model: A73CPUR21-S1
Multi axis positioning controller.
Coaxial data communication line function.
Program capacity: Max 60K step.
Input / output points: 1920 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.

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.
With the surge absorber.
CE certification.

MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian A73CPUR21-S1.
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. 8 slot, PID special substrate.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
I/O points is an important indicator of PLC.
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.
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 A73CPUR21-S1.
Taking into account the future adjustment and expansion,
In general should be estimaated on the total number of points plus the amount of spare 20%~30% A73CPUR21-S1.
The following describes the centralized control system I/O points of the estimate.
