Type of input and output terminal AJ35PJ-8R
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module. 5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
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 AJ35PJ-8R PDF.
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 AJ35PJ-8R PDF.
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.
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%.
The following describes the centralized control system I/O points of the estimate. Analog channel: 16 channels.
Input / output (resolution): 0 ~ 4000.
Conversion speed: 100ms/16 channel.
Analog module installation.
Power supply: AC170V ~ 264V.
According to the control requirements of the system, using the appropriate design method to design MITSUBISHI PLC program.
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 detection, fault diagnosis and display and other procedures.
These procedures are relatively independent, generally in the basic completion of the program design and then add.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and tthe timeliness is strong AJ35PJ-8R datasheet.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy too guarantee the timeliness AJ35PJ-8R datasheet.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
