Input and output points: 256 points.
Input / output data points: 256 points.
Program capacity: 6k.
Basic command processing speed (LD command) s:1.0.
Internal storage RAM memory capacity: 16k.
User program storage capacity: it is a measure of how much the user application can store the number of indicators MITSUBISHI A0J2-C10.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words A0J2-C10
PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure MITSUBISHI A0J2-C10.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. Input voltage: AC100 ~ 120V/AC200 ~ 240V.
Output voltage: DC5V.
Output current: 8A.
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 MITSUBISHI A0J2-C10.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference A0J2-C10 MITSUBISHI. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC A0J2-C10 MITSUBISHI. 2 slots.
Can be installed in the power supply unit for A series units installed QnA/.
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 A0J2-C10 MITSUBISHI.
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 accordiing to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A0J2-C10.
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% MITSUBISHI A0J2-C10.
The following describes the centralized control system I/O points of the estimate.
