5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
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 HC-SFS702BG1 1/43
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 according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point.
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: A950GOT.

Some mechanical industries, such as machine tools, textile machinery, electronic equipment and other industries,
In the country has been developed for decades of history, relatively speaking, is relatively mature industry, in the long run,
These industries also exist the needs of equipment upgrades.
In this upgrading process, there will be some small, has been using relatively low-end products manufacturers are eliminated,
But there are also a lot of enterprises in the process of equipment renewal,
Re positioning the needs to find those that can meet their development plans,
Equipment suppliers to help them improve their productivity.
