32 point connector for welding (37 pin D-Sub connector).8 channels.
Input: DC-10 ~ 10V, DC4 ~ 20mA.
Output (resolution): -2000 ~ 2000.
Transform speed: 2.5ms/1 channel.
47 point terminal station.
Each channel D can be set A/ transform the.
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 A1SJ71E71N-T datasheet PDF catalog A1SJ71E71N-T PDF datasheet A1SJ71E71N-T
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.
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 A1SJ71E71N-T datasheet PDF catalog A1SJ71E71N-T PDF datasheet.
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.
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 A1SJ71E71N-T datasheet PDF catalog A1SJ71E71N-T PDF datasheet.
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.
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. 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.
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 quanttity of the controlled object,
Generally an input / output element to take up an input / output point A1SJ71E71N-T datasheet PDF catalog A1SJ71E71N-T PDF datasheet.
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% A1SJ71E71N-T datasheet PDF catalog A1SJ71E71N-T PDF datasheet.
The following describes the centralized control system I/O points of the estimate.
