NSD servo system.
A73CPU (P21/R21) -S3 dedicated.
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 A2CCPUP21 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 A2CCPUP21
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action A2CCPUP21 PDF.
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 A2CCPUP21 PDF.
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 thhe lowest A2CCPUP21 Manual.
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 MITSUBISHI Programming Manual .
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 MITSUBISHI Programming Manual . Available network: 10BASE2.
Max / total distance: 185/925m.
A1SJ71E71 is a compact Ethernet interface module,
Used to hang PLC series ANS to ethernet.
There are two kinds of hanging network modules: A1SJ71E71-B2-S3 and A1SJ71E71-B5-S3 respectively corresponding to 10BASE2 and 10BASE5,
So that the vast majority of installed cable can continue to use MITSUBISHI Programming Manual . Number of channels: 2 channels.
Sensing methods and temperature range: R, K, J, T, S, B, E, N, U, L, PL, II,, Wre5-26,,, and.
A1S64TC series component is a kind of temperature controller combined with ANS seriies CPU A2CCPUP21 Programming Manual .
Components with temperature measurement input and built-in PID algorithm control output, can be used in a variety of temperature control occasions.
Each component controls up to 4 loops at most.
Thermocouple input or PT100 3 wire temperature sensor input A2CCPUP21 Manual.
Control output switching signal for the output of the transistor.
BW is a signal with broken line detection function.
