Input voltage range: DC24V.
Output voltage: DC5V.
Output current: 2.5A.
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 and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A1SJ71E71-B5 Manual A1SJ71E71-B5 User's Manual A1SJ71E71-B5
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 A1SJ71E71-B5 Manual A1SJ71E71-B5 User's Manual.
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.
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 A1SJ71E71-B5 Manual A1SJ71E71-B5 User's Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action. Screw terminal table type.
Voltage / current output module.
Number of channels: 2 channels.
Number of stations: 1 stops.
Station type: remote equipment station.
MITSUBISHI PLC hardware implementation
Hardware implementation is mainly for the control cabinet and other hardware design and field construction.
Design control cabinet and the operating table and other parts of the electrical wiring diagram and wiring diagram.
Electrical interconnection diagram of each part of the design system.
According to the construction drawings of the site wiring, and carry out a detailed inspection.
Because the program design and hardware implementation can be carried out at the same time,
So the design cycle of the MITSUBISHI PLC control system can be greatly reduced.
MITSUBISHI PLC online debugging.
On-line debugging is the process that will through the simulation debugging to further carry on the on-line unification to adjust.
On-line debuggging process should be step by step,
From MITSUBISHI PLC only connected to the input device, and then connect the output device, and then connect to the actual load and so on and so on stepp by step A1SJ71E71-B5 Manual A1SJ71E71-B5 User's Manual A1SJ71E71-B5 Manual A1SJ71E71-B5 User's Manual.
If you do not meet the requirements, the hardware and procedures for adjustment.
Usually only need to modify the part of the program can be.
