8 channels.
Input: DC-10 ~ 10V, DC4 ~ 20mA.
Output (resolution): -2000 ~ 2000.
Transform speed: 2.5ms/1 channel.
38 point terminal station.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register A985GOT-TBD-V PDF.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive A985GOT-TBD-V
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive A985GOT-TBD-V PDF.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC A985GOT-TBD-V PDF.
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light MITSUBISHI User's Manual.
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian MITSUBISHI User's Manual.
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 MITSUBISHI User's Manual. For A6TBXY36/A6TBXY54/A6TBX70E (common cathode; drain type) long 5m.Applicable model: A975/970/960GOT (-B).5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
When the programmer iinput 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 A985GOT-TBD-V Manual.
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 accordinng to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A985GOT-TBD-V User's Manual.
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% A985GOT-TBD-V Manual.
The following describes the centralized control system I/O points of the estimate.
