MITSUBISHI A68B datasheet PDF datasheet

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 A68B datasheet.
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 A68B
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
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 A68B datasheet.
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 A68B datasheet.
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. Points: 32 points
.
Rated voltage: DC24V.
Connection type: connector
.
Three remote components can be connected to the CC-LINK system.
Remote I/O: refers to those who require only the ON/OFF control function of the field components, such as digital I/O or pneumatic valve, etc..
In this type of communication can only be carried out in the bit data.
Remote components: refers to those that require processing of the register data of the fieeld components, such as analog I/O and counters, etc A68B PDF datasheet. .
In this type of component, in addition to the bit data can be carried out in the register data communication.
Intelligent remote: this type of component is to allow the main sstation or other stations to access the action, to collect data and control the local PLC station,
GOTS and programmer interface unit are of this type A68B PDF datasheet.
