Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input DC5V output 2A DC24V/ AJ72BR15 PDF.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units AJ72BR15 16 bit binary number is a word,
Every 1024 words are 1K words. 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 AJ72BR15 PDF. Data operation instructions for 2~4.
Relay output interface circuit of PLC
Working process: when the internal circuit outpuut 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 AJ72BR15 PDF AJ72BR15 Manual .
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 MITSUBISHI Reference Manual . A pack of 20.
Applicable models:
AJ65SBTC - - - type remote I/O module.
AJ65VBTCU - - - type remote I/O module.
AJ65VBTCU- - type remote I/O module. Input voltage range: DC110V.
Output voltage: DC5V MITSUBISHI Reference Manual .
Output current: 8A.
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 aand switch quantity of the controlled object,
Generally an input / output element to take up an input / output point MITSUBISHI Reference Manual AJ72BR15 Reference 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% AJ72BR15 Manual .
The following describes the centralized control system I/O points of the estimate.
