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 A975GOT-TBD 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 A975GOT-TBD
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% A975GOT-TBD 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 A975GOT-TBD PDF.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relayy 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 User's Manual A975GOT-TBD Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action. Storage capacity: 16MB.
Applicable models: A985 (-V) /A975/A970/A960GOT (-B). 3C-2V/5C-2V coaxial cable between double loop PC (control station / common station) / remote I/O network (remote master station) MITSUBISHI User's Manual.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on MITSUBISHI User's Manual.
This phenomenon is called the I/O delay time effect.
Switch volume control is designed to,
According to the current input combinatioon of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order A975GOT-TBD User's Manual.
So, sometimes also known as the order control.
And seqquential control is divided into manual, semi-automatic or automatic A975GOT-TBD Manual.
And the control principle is decentralized, centralized and hybrid control three.
