38 point terminal station.
Analog I/P multiplexing unit.
Detailed analysis of the process and work characteristics of the controlled object,
To understand the coordination between the controlled object machine, electricity and liquid,
The control requirements of the controlled object for MITSUBISHI PLC control system are put forward,
Determine the control program, to develop a design task book A1SX41-S1 PDF A1SX41-S1
How to determine the input / output device of MITSUBISHI plc.
According to the control requirements of the system,
All input devices and output devices required for the determination of the system,
To determine the input / output device related to the MITSUBISHI PLC,
To determine the I/O PLC points A1SX41-S1 PDF. Output type: transistor output, drain type.
Output points: 8 points.
OFF leakage current: 0.1mA.
Output protection function: No.
Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 1 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup A1SX41-S1 PDF.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool. Input voltage range: AC100 ~ 120V.
Output voltage: DC24V.
Output current: 0.6A.
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.
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 A1SX41-S1 datasheet.
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% A1SX41-S1 datasheet.
The following describes the centralized control system I/O points of the estimate.
