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 GT15-DIO.
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 GT15-DIO
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action GT15-DIO.
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 GT15-DIO.
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. Series Name: A951GOT.

China is the world''s biggest market for human machine interface,
But it is not the highest sales market in the world,
This shows that the low-end user interface in China has a large share of.
In recent years, the rapid development of national brands, to take a low price and other strategies, is a massive aattack on the low end of thee market,
Has occupied the dominant position in the low-end market, has won the recognition of the majority of users GT15-DIO.
International brands are also gradually developing its economic products, in order to seize the share of the low-end market.
Thereefoore, in the low-end market steady,
The overall performance of the domestic human machine interface manufacturers showing a rapid growth of the state GT15-DIO.
