MITSUBISHI A1S62RD4 User's Manual PDF

5 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 A1S62RD4 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 A1S62RD4
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action A1S62RD4 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 the lowest.
The input and output poinnts 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 A1S62RD4 PDF A1S62RD4 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% MITSUBISHI User's Manual.
The following describes the centralized control system I/O points of the estimate. Input and output points: 512 points.
Input / output data points: 512 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1 MITSUBISHI User's Manual. 0.
Optical data communication line.
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. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words MITSUBISHI User's Manual.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions forr 2~4 A1S62RD4 User's Manual.
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 A1S62RD4 Manual .
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
