MITSUBISHI MR-J3-22KA

5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
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 MR-J3-22KA.
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 MR-J3-22KA
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 MR-J3-22KA.
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 MR-J3-22KA.
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. Drive: MR-H_ACN series SSC-NET compatible AC servo.
Rated output: 15KW.
The servo controller can easily transfer the operation module and the field bus module through the automation interface,
At the same time using different fieldbus modules to achieve different control modes (RS485, RS232, optical fiiber, InterBus, ProfiBus),,
And the control mode of general inverter is single MR-J3-22KA.
The servo controller is directly connected with a rotary transformer or an encoder, which forms a closed loop of speed and displacement control.
The general inverter can only form an open loop cconntrol system MR-J3-22KA.
Servo controller of the control parameters (such as steady-state accuracy and dynamic performance) is better than the general inverter.
