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 A970GOT-SBA-EU PDF.
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 A970GOT-SBA-EU
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% A970GOT-SBA-EU PDF.
The following describes the centralized control system I/O points of the estimate.
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 A970GOT-SBA-EU 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 MITSUBISHI Operating Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load acction or not action A970GOT-SBA-EU Manual. Output type: relay.
Output points: 12 points.
Load voltage: AC240/DC24.
Load current: 2A.
Connection mode: terminal row.
Common public end points: 4 MITSUBISHI Operating Manual.
Sequential function flow chart language is designed to satisfy the sequential logic control.
The process of sequential process action is divided into steps and transformation conditions,
According to the transfer condition, the control system is distributed in the function flow sequence,
Step by step according to the sequence of actions MITSUBISHI Operating Manual.
Each step represents a control function, represented by the box.
In the box, the ladder logic is used to complete the task of the corresponding control function.
This programming language makes the program structure clear and easy to read and maintain,
Greatly reduce the programming workload, shorten the programming and debugging time.
Used in the system of the size of the school, procedures for more complex occasions.
Sequence function flow chart programming language features: to function as the main line, in accordance with the functional flow of tthe order of distribution, clear, easy to understand the user program,
Avoid the defect of ladder diagram or other languages,
At the same time, the use of ladder language to avoid the use of ladder programming,
Due to the compllicated mechanical interlock, the structure of the user program is complex and difficult to understand,
User program scan time is also greatly reduced A970GOT-SBA-EU Manual A970GOT-SBA-EU Operating Manual.
