A273UHCPU MITSUBISHI A273UHCPU

Input voltage range: DC110/125V.
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 A273UHCPU.
Reasonabble 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 A273UHCPU.
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% A273UHCPU.
The following describes the centralized control system I/O points of the estimate. Twisted pair cable.
Single bus.
MELSECNET/B (remote I/O station).
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program MITSUBISHI A273UHCPU.
Procedures to meet the requirements of system control as the main line,
Write one by one to achieve the control function or the sub task of the program,
Gradually improve the functions specified by the system.
MITSUBISHI PLC initialization procedure MITSUBISHI A273UHCPU. After MITSUBISHI PLC on power, the general need to do some of the initial operation,
In order to start making necessary preparations, to avoid the wrong operation of the system.
The main contents of the initialization program are: to some data area, counter and so on,
Data needed to restore some of the data area,
Set or reset some relays,
For some initial state display, etc MITSUBISHI A273UHCPU..
MELSECNET/10, MELSECNET/H coaxial.
Input voltage: DC24V.
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.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc A273UHCPU..
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.
